Select the correct statement about the physical factors influencing pulmonary ventilation.
a. Surfactant helps increase alveolar surface tension.
b. As alveolar surface tension increases, additional muscle action will be required
c. A lung that is less elastic will require less muscle action to perform adequate ventilation.
d. A decrease in compliance causes an increase in ventilation.

Answers

Answer 1

Answer:

Option (b).

Explanation:

Pulmonary ventilation is the mechanism of respiration in which the oxygen is inhaled in the body and carbon dioxide is exhaled out due to the pressure difference in the lungs and the environment.

The surface tension in the alveoli is decreased by the presence of surfactant. The increase in the surface tension of the alveoli increase the force that will require the additional muscles to work properly.

Thus, the correct answer is option (b).

Answer 2
Final answer:

The correct option is (b) as increasing alveolar surface tension requires greater muscle effort for ventilation. This is because increased alveolar surface tension makes it harder for the lungs to expand.

Explanation:

The correct statement about the physical factors influencing pulmonary ventilation is (b) As alveolar surface tension increases, additional muscle action will be required. The reasoning behind this is that surface tension in the alveoli challenges the expansion of the lungs. Alveoli are tiny air sacs in the lungs where the exchange of gases occur. Therefore, if the surface tension in these alveoli increases, the lungs will find it more difficult to expand necessitating extra muscle effort for adequate ventilation. (a) is incorrect because surfactant actually reduces alveolar surface tension, not increase it. (c) and (d) are incorrect because a decrease in lung elasticity and lung compliance both lead to an increased effort for ventilation, not a decrease.

D) granulosum
E) lucidum

Answers

Answer:

The correct option is B) Papillary

Explanation:

The thick layer of skin present between the subcutaneous tissues and the epidermis (outermost layer of skin), is known as the dermis. The dermis consists of elastic and fibrous tissues, which cushions the body from any external stress.

The dermis consists of two sub layers- the papillary region and the reticular dermis.

The papillary dermis is the uppermost layer present in the pepillary region of the dermis.

Which statement about CO2 is incorrect?
a. CO2 concentrations are greater in venous blood than arterial blood
b. More CO2 dissolves in the blood plasma than is carried in the RBCs.
c. Its accumulation in the blood is associated with a decrease in pH.
d. Its concentration in the blood is decreased by hyperventilation.

Answers

Answer:

The option which is incorrect is B) more CO 2 dissolves in blood plasma than is carried in the red blood cells.

Explanation:

All the options here except B) are correct, as CO 2 which is also know as carbon dioxide, it is know to be more soluble than oxygen in the blood as it is said that almost 5% - 7% of CO 2 gets dissolved in the plasma . Carbon dioxide is found in greater concentrations in venous blood than the arterial blood. Through the bicarbonate buffer system, which allows a less change to the pH of the body system ,and through this it allows a person to live at high altitude places by regulating the amount of carbon dioxide. So we can say that its accumulation in the blood is linked with a decrease in pH. But more of the CO 2 doesn't dissolve in the plasma than is carried in the plasma as only 5-7 % of CO 2 is dissolved in plasma.

The correct answer is option b. The incorrect statement about CO₂ is that more CO₂ dissolves in the blood plasma than is carried in the RBCs.

- CO₂ is transported in the blood in three forms: dissolved in plasma (about 5-7%), bound to hemoglobin in red blood cells (RBCs) (about 20-30%), and as bicarbonate ions [tex](HCO_3^-)[/tex] (about 60-70%).

- When CO₂ diffuses into the RBCs, it reacts with water to form carbonic acid (H₂CO3), which quickly dissociates into bicarbonate ions [tex](HCO_3^-)[/tex] and protons [tex](H^+)[/tex]. This reaction is catalyzed by the enzyme carbonic anhydrase, which is present in high concentrations in RBCs.

- The bicarbonate ions then move out of the RBCs into the plasma in exchange for chloride ions [tex](Cl^-)[/tex], a process known as the chloride shift. This means that the majority of CO₂ is transported as bicarbonate ions in the plasma, not dissolved in the plasma.

- The hemoglobin in RBCs also binds to CO₂, forming carbaminohemoglobin, which is another form of CO₂ transport within RBCs.

Now, let's address the other options:

a. CO₂ concentrations are greater in venous blood than arterial blood - This is correct. Venous blood has a higher concentration of CO₂ because it has picked up CO₂ from the tissues, which is then transported to the lungs for exhalation.

c. Its accumulation in the blood is associated with a decrease in pH - This is correct. As CO₂ levels increase in the blood, it leads to the formation of more carbonic acid, which dissociates into bicarbonate and protons ([tex]H^+[/tex]), thus decreasing the blood pH, leading to acidosis.

d. Its concentration in the blood is decreased by hyperventilation - This is correct. Hyperventilation increases the rate of respiration, leading to more CO₂ being exhaled than normal. This results in a decrease in the concentration of CO₂ in the blood.

Which of the following is an irigation catheter used after transurethral prostatic surgery?
A. ureteral stent
B. three-way Foley
C. Robinson
D. Malecot

Answers

Answer: B. Three-way Foley

Explanation:

In the case of this postoperative, the catheter that is used is a Three-way Foley.

After the surgery, the physician needs to know who much blood and how much urine is going out by the urethra; and how much of those are produced after the surgery. It helps to know if the tissue is healing, I mean, if there is less blood every day, then the outcome of the surgery could be better.  

The Three-way Foley also has a bag at the end that allows to measure the quantity of the urine that is expected to produce every day.  

The three-way Foley is also a catheter with a balloon that inflates inside the bladder in order to keep the catheter in position, until the physician tell the patient, it is time to pull out.  

Surfactant ______ surface tension in the alveoli, making the lung ______ compliant and thereby ________ the work required to inflate it.
A. Decrease, less, increasing
B. Increase, more, decreasing
C. increase, less, increasing
D. decrease, more, decreasing

Answers

Answer:  Option D " decrease, more, decreasing"

Explanation:

Pulmonary surfactant can be defined as the surface-active proteins which is made of type II alveolar cells. These surfactant is made of protein and lipids which are both hydrophobic and hydrophillic in nature.

It greatly reduces the surface tension in the alveoli, which make the lungs more compliant (ability of the lungs to stretch and expand) and hence, decreases the work required to inflate it.

Thus the correct answer is option D

What is electrical firing mechanism of the heart?

Answers

Answer:

The process of contraction and relaxation to pump blood to heart by atria and ventricles together is called electrical firing mechanism of the heart.

The electrical system regulates the timing of heartbeat through sending electrical signal.

The electrical signal originates in a group of cells at the top of heart known as  sinoatrial (SA) node and send the signal to right and left atria that triggers the atria muscles to get contract. after atria contraction the blood transfer to left and right ventricles and electrical signal arrives at atrioventricular node (AV node) that slows down the electrical signal and provide time to receive blood from atria to ventricles. electrical signal then move to ventricle muscles and allow them to contract. The left ventricle pumps blood to all body parts and right ventricle pumps blood to lungs.

After contraction of both atria and ventricles the electrical mechanism resets itself and follows the same process again.

Final answer:

The electrical firing mechanism of the heart coordinates the rhythmic contractions of the heart muscles and is responsible for pumping blood. It starts with the sinoatrial (SA) node and involves the atrioventricular (AV) node, bundle of His, bundle branches, and Purkinje fibers. The resulting electrical currents can be measured as an electrocardiogram (ECG).

Explanation:

The electrical firing mechanism of the heart is responsible for coordinating the rhythmic contractions of the heart muscles, allowing it to pump blood through the circulatory system. The process starts with the heart's natural pacemaker, called the sinoatrial (SA) node, which sends out electrical impulses that cause the atria to contract. From there, the impulses travel to the atrioventricular (AV) node, the bundle of His, the bundle branches, and finally the Purkinje fibers, which stimulate the ventricles to contract. This coordinated electrical activity produces the characteristic electrical currents that flow through the body and can be measured as an electrocardiogram (ECG).

A neurotransmitter of the sympathetic division of the nervous system that increases the heart rate and constricts smooth muscle in blood vessels to raise blood pressure in the "fight or flight" response is called:

The incorrect levels of epinephrine will characterize a person suffering an anxiety disorder. If a situation requieres a stress response, epinephrine will help a living organism like mammals to answer quickly and surive.

Final answer:

The neurotransmitter that increases the heart rate and constricts blood vessels to raise blood pressure in the 'fight or flight' response is epinephrine (adrenaline).

Explanation:

The neurotransmitter associated with the 'fight or flight' response within the sympathetic division of the nervous system is a. epinephrine. Also known as adrenaline, epinephrine is responsible for increasing heart rate and constricting smooth muscle in blood vessels, which elevates blood pressure. This neurological reaction prepares the body to react in stressful or potentially dangerous situations.

d. a and b are correct
e. a, b and c are correct

Answers

Answer:

The correct answer to the question: Chronic Obstructive Pulmonary diseases (COPD), include:____, would be, D: a and b are correct.

Explanation:

COPD, or best known as Chronic Obstructive Pulmonay Disorder, is the general name given to a disease in which the lungs are incapable of performing their task of oxygen and carbon dioxide exchange, because of an obstruction either of the airways, or the alveoli, which are the sacks in which the actual exchange takes place. This obstruction can happen either because of an overproduction of mucus, or because the airways become fibrous, and therefore, oxygen cannot be exchanged. The other reason is when the alveoli are damaged and destroyed and air sacks form in the lungs. In COPD, we have two types: Chronic Bronchitis, in which due to continuous coughing, and mucus production, the bronchi become inflamed and fibrous and therefore exchange is much more difficult. In the second form, we have emphysema, in which the constant coughing starts affecting the lining of the alveoli, until it can literally be destroyed and pockets of air can form inside the actual lung tissue.

The pancreas releases alkaline, enzyme-rich pancreatic juice into the ____________ of the small intestine. What is the function of this juice?

Answers

Answer:

The correct answer is the duodenum.

Explanation:

Pancreatic juice is an alkaline fluid which contains important enzymes for the digestion of proteins, carbohydrates and fats.  

Pancreatic juice is secreted by the pancreas when food enters the stomach which is released into the "duodenum" of the small intestine. The pancreatic juice enters duodenum through a pancreatic duct which joins with the bile duct coming from the liver and form "ampulla of Vater" in the duodenum.

Pancreatic juice helps in digestion of carbohydrates, proteins and fats as it contains pro-enzymes and enzymes like trypsinogen, chymotrypsinogen, lipase and many more. It also makes the acidic stomach solution alkaline due to the presence of HCO₃.

Thus, the duodenum is the correct answer.

e. Why did you make that prediction?

Answers

Answer:

i need the answer

Explanation:

Final answer:

ADH regulates the body's water conservation process. Amber should stay hydrated to prevent dehydration, while other hormonal mechanisms may step in to compensate the decreased ADH. First signs of dehydration include thirst, dark urine, dry mouth, fatigue, lightheadedness.

Explanation:

ADH, or antidiuretic hormone, plays a crucial role in maintaining the body's water balance. Released by the pituitary gland, it increases the water permeability of kidney's collecting ducts, promoting water reabsorption back into the bloodstream and thus limiting its loss in urine.

Amber, with decreased ADH effectiveness, would likely produce larger amounts of urine, possibly leading to dehydration. To prevent serious side effects, Amber must stay adequately hydrated, monitor her urine output and consistency, and seek medical help if signs of dehydration occur. First signs of dehydration often include thirst, darker than normal urine, dry mouth, fatigue, and lightheadedness.

With decreased ADH function, other hormonal mechanisms in the kidney, like the renin-angiotensin-aldosterone system, may be stimulated to maintain fluid balance. This system can conserve sodium, which in turn retains water, decreasing the likelihood of dehydration.

This prediction was made because the body has numerous systems in place to maintain homeostasis, if one fails, others often step in to compensate.

Factors which thicken the respiratory membrane may result in __________
a. oxygen deprivation
b. reduced pulmonary circulation
c. bronchiole constriction
d. none of the above

Answers

Answer: d. none of the above

Explanation:

The respiratory membrane is the membrane which separates the air inside the alveoli from the pulmonary capillaries. The types of respiratory membranes includes the alveoli membrane, the capillary membrane and the basement membrane. The respiratory membrane is usually very thin. But it becomes thick due to the increase in the fluid content, which actually forces the gases to diffuse through the membrane and the fluid. Also the pulmonary diseases can also cause the membrane to become thick.

Answer: Oxygen Deprivation

Explanation:

The thickening of the respiratory membranes may result in the oxygen deprivation. The function of membrane is to help in gaseous exchange.

The carbon dioxide is removed out of the body and oxygen is inhaled inside. Thickening of the membrane will reduce the ability to exchange gas which will make the body deprive of oxygen.

There are may diseases in which the thickening of the respiratory membranes takes place.Example: pulmonary fibrosis.

What happens to alveolar volume and intra-alveolar pressure during exhalation?
1. Decrease alveolar volume causes an increase alveolar pressure
2. Increase alveolar volume causes an increase alveolar pressure
3. Decrease alveolar volume causes a decrease alveolar pressure
4. Increase alveolar volume causes an increase alveolar pressure

Answers

Answer:

The correct answer will be option A.

Explanation:

Exhalation is a  mechanism of breathing which exhales out the gases from the lungs to the atmosphere.

During the exhalation process the thoracic volume decreases which decrease the lung volume. This decreases alveolar volume.  Due to this decrease in alveolar volume the intra- alveolar pressure increases above atmospheric pressure up to +2 cm of H₂O which results in the release of the gas or air out of the lungs.

Thus, option A is the correct answer.

Final answer:

During exhalation, the alveolar volume decreases, resulting in increased intra-alveolar pressure, leading to air being expelled from the lungs.

Explanation:

The relationship between the pressure and volume of a gas in the context of alveolar function during respiration can be explained by Boyle's Law, which states that pressure and volume have an inverse relationship. When a person exhales, the muscles of the lungs and chest wall contract, causing alveolar volume to decrease. This decrease in volume leads to an increase in intra-alveolar pressure because the same amount of gas is confined to a smaller space. Consequently, intra-alveolar pressure becomes higher than atmospheric pressure, causing air to flow out of the lungs.

An abnormal sound (murmur) due to narrowing or stenosis of the mitral valve might be heard during:
a. diastole
b. systole

Answers

Answer:

The correct answer to the question: An abnormal sound (murmur) due to narrowing or stenosis of the mitral valve might be heard during:____, would be, A: Diastole.

Explanation:

It is first important to know that a murmur comes from the sound the blood makes as it passes either through a hardened tissue, like is the case of stenosis of a valve, or because it leaks back from where it came, due to regurgitation, because the valve is defective and cannot close properly. During the cardiac cycle, there is a process of systole, and of diastole, that ensure the filling and expulsion of the blood inside the heart towards the body, and from the body into the heart, so that a constant flow is ensured. In the process of filling and emptying, two sets of valves, the mitral and tricuspid, and the aortic and pulmonary, open and close to allow blood flow towards the different chambers of the heart, and out into the blood vessels of the body, and prevent the blood from returning towards where it came. In the case of mitral stenosis, which is the toughening of the mitral valve of the heart, the blood flowing through it makes a murmuring sound that can be caught up through a stethoscope. This sound is prominent during diastole, and that is why medically this murmur is known as a diastolic murmur.
