Answer:
The test to determine the blood group is called ABO typing. A blood sample is mixed with the antibodies against blood type A and type B. Then, the sample is checked to see if the blood cells stick or not. If the blood cells remain together that means that the blood reacted with one of the antibodies.
Where can you find the following?
a. costal cartilage
b. bones
c. articular cartilage
d. fibrocartilage of IVD
e. epiphyseal plate
Answer:
a. costal cartilage - at the anterior ends of the ribs.
b. bones - complete skeletal system.
c. articular cartilage - covers the ends of bones at joints.
d. fibrocartilage of IVD - the annulus fibrosus of intervertebral discs
e. epiphyseal plate- in a long immature bones
Explanation:
The costal cartilages are spokes of hyaline cartilage that help to extend the ribs forward and assist in the elasticity of the walls of the thoracic cage. It is found at the anterior or front ends of the ribs.
Thus, costal cartilage - at the anterior ends of the ribs.
The human skeletal system made up of 206 bones all over the body, as well as a network of ligaments, tendons, and cartilage that connects them.
Thus, bones - complete skeletal system.
Articular cartilage covers the ends of bones where they assemble to form joints.
Thus, articular cartilage - covers the ends of bones at joints.
Fibrocartilage is A very strong tissue present in predominantly in the IVD or intervertebral disks. It attaches soft tissue-to-bone attachments.
Thus, fibrocartilage of IVD - the annulus fibrosus of intervertebral discs
The epiphyseal plate is the region of growth in a long bone that is present in immature bones.
Thus, epiphyseal plate- in a long immature bones
Which of the choices below is not a factor that promotes oxygen binding to and dissociation from hemoglobin?
a. partial pressure of oxygen
b. temperature
c. partial pressure of carbon dioxide
d. number of red blood cells
The number of red blood cells does not promote oxygen binding to and dissociation from hemoglobin. Factors like the partial pressure of oxygen, temperature, and the partial pressure of carbon dioxide influence this process, but the number of red blood cells simply affects the volume of blood and its oxygen-carrying capacity.
Explanation:The factor among those listed that does not promote oxygen binding to and dissociation from hemoglobin is the number of red blood cells. Hemoglobin is a protein in red blood cells that carries oxygen. Factors like the partial pressure of oxygen, temperature, and the partial pressure of carbon dioxide influence the ability of oxygen to bind and unbind from hemoglobin because they affect the affinity, or attraction, of hemoglobin to oxygen. Meanwhile, the number of red blood cells affects the volume of blood itself and the oxygen-carrying capacity of the blood, but not the binding and dissociation process of oxygen with hemoglobin.

Causes of metabolic alkalosis include all of the following except?
A. Mineralocorticoid in excess
B. Hypokalemia
C. Recurrent diarrhea
D. all of the choices apply
Answer:
B. Hypokalemia
Explanation:
symptoms and signs of mild alkalemia are usually related to the underlying disorder. More severe alkalemia increases protein binding of ionized calcium, leading to hypocalcemia and subsequent headache, lethargy, and neuromuscular excitability, sometimes with delirium, tetany, and seizures. Alkalemia also lowers threshold for anginal symptoms and arrhythmias. Concomitant hypokalemia may cause weakness.
In conditions of metabolic alkalosis, mineralocorticoid excess and hypokalemia can be contributing factors. On the other hand, recurrent diarrhea typically leads to metabolic acidosis, not alkalosis, due to the loss of bicarbonate from the body. Hence, the exception among the provided options is recurrent diarrhea.
Explanation:The condition described in this question is metabolic alkalosis, an alkalinization of the blood due to metabolic processes. Among the options, A. Mineralocorticoid in excess and B. Hypokalemia can indeed contribute to metabolic alkalosis. Mineralocorticoid excess leads to increased renal absorption of sodium and loss of hydrogen and potassium ions, which contributes to the alkalinization of the blood. Hypokalemia, or low potassium levels, can also contribute to metabolic alkalosis as hydrogen ions move into cells in exchange for potassium, decreasing the acidity of the blood. However, C. Recurrent diarrhea is not a typical cause of metabolic alkalosis; instead, it commonly causes metabolic acidosis because of bicarbonate loss from the body and the compensatory increase in acid products. Thus, the answer is C. Recurrent diarrhea.

One function of the immune system is to attack the foreign cells to protect the body. In organ transplants, how does the immune system usually reacts with the transplanted organ?
Answer:
The immune system of a transplant recipient recognizes this as a foreign agent and activates its defense mechanism against it. The antigens present in the transplanted organ are detected by the recipient organism, as different or not compatible, which will cause a reaction or rejection, activating an immune response. These rejections can be acute or chronic depending on how strange or compatible the transplant is for the recipient.
Answer:
Explanation:The immune system of a transplant recipient recognizes this as a foreign agent and activates its defense mechanism against it. This starts to slowly destroy the organ. to help prevent this, doctors usually give you immunosuppressant (anti-rejection) drugs. These drugs help prevent your immune system from attacking ("rejecting") the donor organ. Typically, they must be taken for the lifetime of your transplanted organ.

The two hormones secreted by the pancreas that regulate blood sugar levels are ___________ and ___________.
Answer:
Insuline and glucagon
Explanation:
Insuline is produced in the beta cells when the carbohydrates levels rise in plasma so they can be transported to other cells that need the glucose.
The glucagon is produced in the alpha cells in the islets of langerhans, the glucagon raises the glucose levels in the bloodstream when it is needed so the glucagon promotes the gluconeogenesis and glycogenolysis, this hormone is catabolic meanwhile the insule is an anabolic hormone
What initiates the defecation reflex?
Answer:

Where within the GI tract does protein digestion begin? Where is protein digestion completed?
Answer:
Pepsins are digestive enzymes of the stomach. These enzymes are the ones that begin the digestion of the proteins giving rise there initially to the formation of polypeptides, oligopeptides and some amino acids.
The digestion of proteins is completed in the small intestine.
Final answer:
Protein digestion starts in the stomach with HCl and pepsin breaking down proteins into polypeptides. The process is completed in the small intestine with several enzymes converting polypeptides into amino acids.
Explanation:
The digestion of proteins begins in the stomach, where hydrochloric acid (HCl) and the enzyme pepsin start the breakdown of proteins into smaller chains called polypeptides. This initial stage involves the hydrolysis of protein linkages, which is the process of breaking the bonds within protein molecules through the addition of water facilitated by gastric juices. Following this, the digestion of proteins is completed in the small intestine, where a host of enzymes from the pancreas, such as chymotrypsin and trypsin, as well as enzymes from the intestinal lining, including aminopeptidase and dipeptidase, further break down polypeptides into amino acids. These amino acids are then small enough to be absorbed into the bloodstream, providing the body with the necessary components for various physiological functions.

Which of the conditions would be most likely to cause a decrease in core temperature?
A. Increased thyroxine secretion
B. decreased T4 secretion
C. increase epinephrine secretion
D. Peripheral vasoconstriction
Answer:
B. decreased T4 secretion
Explanation:
T4 (thyroxine) is amino acid derived hormone, synthesized and secreted by thyroid gland. The main function of T4 hormone is to regulate body metabolism.
Thyroid hormones are also responsible for temperature regulation as increased T4 secretion increases temperature of body by increasing metabolism. Under hypothyroidism (decreased secretion of T4) leads to decrease in body temperature.

It is part of a group of medications called by its mechanism of action as ANGIOTENSIN-CONVERTING-ENZYME INHIBITORS (ACE inhibitors), along with Captopril, Cilazapril, Enalapril, Fosinopril, among others. One of the most common side effects is dry cough, that could appear since, one week after beginning the treatment or even six weeks later. The cough does not respond to any treatment, except if the medication is stopped.
The Furosemide, Diltiazem, and Metoprolol do not have dry cough described as a side effect. Furosemide: electrolyte disturbances (of calcium, magnesium, sodium). Diltiazem: Dizziness, headache, diarrhea. Metoprolol: Bradichardia, gastrointestinal symptoms.
Describe babinski's sign. Is this normal in an adult?
Answer:
When performing a neurological assessment, especially of whether or not there is a spinal cord lesion, there is one reflex that is easy to test, and which will tell medical professionals if there is a damage to the central nervous system, or not. This test is called the Plantar Reflex. Essentially, when the later side of the sole of the foot is stimulated with a blunt object, from heel to metatarsal pads, in adults, there are two expected results, the first, the foot curving inwards with the full toes towards the point of pressure, or, there is no response from the foot to the stimulus. However, there is a third possible response, which is pathological, and it is known as the Babinsky sign, in honor of neurologist Joseph Babinsky.
The Babinsky sign, then, which is an abnormal response, and if present, it is called a positive Babinsky sign, is defined as the motor response of the foot to stimulus of the sole by extending outwards, with the big toe fully extended upwards, while the other toes fan out.
When this sign appears in adults, it indicates a damage to the nerves of the spinal cord, or the brain.
Rubeola is a type of measles that typically lasts:
A. 1 day.
B. 1 to 3 days.
C. 5 days.
D. 7 days.
Answer:
The correct option is D. 7 days.
Explanation:
Rubeola is a highly infectious disease caused by the measles virus. It is a highly contagious disease and can be easily transmitted to other human beings through air.
In this infection, symptoms are seen usually experienced 2 weeks after the exposure to the virus. The symptoms include cold, cough, fever, inflammation of eyes etc. 3-5 days after the start of symptoms, a red rash generally appears on the face and then spreads on the body.
Therefore, the Rubeola disease typically lasts for about 7- 10 days.
Define and differentiate Central nervous system vs peripheral nervous system
Answer:
Central nervous system is comprised of brain and spinal cord. Various sorts of sensory information are integrated and correlated within the central nervous system. In central nervous system, thoughts and emotions are generated and memories our farm and stored.
Peripheral nervous system is comprised of cranial nerves that are arising from the brain and the spinal nerves that are arising from the spinal cord
Explanation:
The central nervous system consists of the brain and spinal cord, controlling most functions of the body and mind, while the peripheral nervous system is the network that sends signals between the central nervous system and the limbs and organs, essentially enabling communication with the rest of the body.
Explanation:Central Nervous System (CNS) vs. Peripheral Nervous System (PNS)
The central nervous system (CNS) comprises the brain and spinal cord, serving as the control center for processing information and directing responses. Enclosed within the cranial and vertebral cavities, the CNS functions as the power plant, orchestrating complex neural functions and overall bodily coordination.
The peripheral nervous system (PNS), in contrast, acts as the wiring that connects the CNS to the muscles, organs, and senses spread throughout the body. It includes thick bundles of axons called nerves, carrying messages to and from the CNS. The PNS is further divided into the somatic nervous system, which manages voluntary movements, and the autonomic nervous system, controlling involuntary actions.

Explanation:
Syphilis can only be spread during stages one and two.
a) True b) False
Answer:
The correct answer to the question: Syphilis can only be spread during stages 1 and 2, would be: false.
Explanation:
Syphilis is a sexually transmittable disease caused by a bacteria. I can only be gotten through sexual activity, or contact with the body fluids or lessions of someone infected, but in order for this contagion to be possible, the person must either be in the initial, or stage 1 of the infection, stage 2 of the infection, or if they are in a stage called the latent stage. This latter, the latent stage, is usually the more dangerous because people don´t tend to show signs, or symptoms of it, which does not mean that the infection is not there. So, in general, there would be really three, out of the four, stages, during which syphilis can be spread to others, and not just the two initial ones. This is why the statement is false.
Describe the function of erectile tissue in the male reproductive system, and how is it supplied with blood.
Erectile tissue such as the corpora cavernosa and corpus spongiosum in the male genitalia becomes filled with blood during sexual arousal, causing an erection necessary for sexual intercourse. Testosterone production is regulated by a negative feedback loop involving the testes and endocrine system, and is crucial for male sexual functions.
Explanation:The function of erectile tissue in the male reproductive system is to enable penile erection, which is crucial for sexual intercourse. The erectile tissue, which includes the corpora cavernosa and corpus spongiosum, becomes engorged with blood upon sexual arousal. This engorgement occurs due to the dilation of arteries supplying blood to the male genitalia, and the subsequent compression of veins that would normally carry blood away, leading to an accumulation of blood within the erectile tissue.
Testosterone plays a vital role in maintaining the sex organs and sex drive, and is produced in a controlled manner by the testes and endocrine system via a negative feedback loop. Leydig cells in the testes secrete testosterone under the influence of luteinizing hormone (LH) from the pituitary gland, which is essential for sexual development and maintaining normal spermatogenesis after puberty.
What is the basic defect of a disease that causes intrapulmonary shunting?
Answer:
Intrapulmonary shunting can be defined as the pathological condition which results when there is an imbalance between the perfusion of air reaching the alveoli to blood.
In other words, Intrapulmonary shunting takes place when the alveoli of lungs perfused normally with blood, but ventilation or the supply of air become unable to supply the perfused region.
Intrapulmonary shunting can result into hypoxemia in pulmonary edema and can cause pneumonia in which lungs become consolidated.
The relatively high pressure in the glomerulus is related to the fact that the
a. afferent arteriole is part of the systemic arterial circulation.
b. efferent arteriole is larger in diameter that the afferent arteriole.
c. glomerulus has constricted capillaries.
d. afferent arteriole has a larger diameter than the efferent arteriole.
Answer:
The correct answer will be option D.
Explanation:
The glomerulus is a small tuft like structure formed by the clusters of the small capillaries in around the end of kidney tubule.
The glomerulus plays an important role in the formation of urine as it filters the blood in the kidney. The filtration rate of glomerulus depends on the glomerulus pressure which is measured generally high due to the size difference of the arterioles that brings the blood to the kidney and that takes the blood from the kidney that is afferent arteriole and efferent arteriole.
The smaller diameter of the efferent arteriole causes the resistance to blood flow which produces the blood to be retained in the glomerulus which creates high pressure in the glomerular cavity.
Thus, option D is the correct answer.
