Answer:
A. Inhibit FSH secretion.
Explanation:
Inhibin is a hormone secreted by the granulosa cells in the ovaries of women and the Sertolli cells in men. The main function of inhibin, as they name says, is to inhibit the secretion of FSH by the anterior pituitary gland. Inhibin is also produced by the Sertolli cells in the testes of men, and it is released in the blood when the sperm count is too high. FSH causes the Sertoli cells of the testes to begin the process of spermatogenesis in the testes. Therefore, releasing inhibin would cause a negative feedback and stop the production of sperm.

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.

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.
Describe the mechanisms of calcium homeostasis: hormones that regulate hypo and hypercalcemia.
Answer:
The hormones involved in the calcium homeostasis are parathyroid hormone, cholecalciferol and calcitonin.
Explanation:
The maintenance of calcium level in the body is important for the proper functioning of body. The increased level of calcium is known as hypercalcemia and low level of calcium in body is known as hypocalcemia.
Hormones that regulate the level of calcium in blood are as follows:
Parathyroid hormone: The parathyroid hormone stimulate the calcium reabsorption in case of hypocalcemia. The osteoclast bone activity increases and calcium reabsorption from renal tubule, increases the calcium level of the body. This maintains calcium homeostasis in the body.
Calcitonin: An increase in the calcium ion concentration stimulates the secretion of calcitonin. The calcitonin hormone inhibits the osteoclast bone reabsorption, decreases the blood level in the body.
Cholecalciferol: This is also known as vitamin D metabolites. This hormone is stimulated in case of low calcium levels. The calcium level can be increased in the body by increasing the phosphate and calcium absorption from the gastro intestinal tract.

An osteon, or Haversian system, is the basic structural unit of compact bone. It contains concentric lamellae around a central Haversian canal, which houses blood vessels and nerves. Within the osteon, living osteocytes reside in cavities called lacunae and are connected by canaliculi.
Explanation:The Osteon, also known as the Haversian system, forms the basic structural unit of a compact bone. It's a cylindrical structure that includes concentric layers called lamellae, which surround a central canal known as the Haversian canal. This Haversian canal contains blood vessels, nerves, and lymph vessels that are essential for bone health and function.
Osteons also house living cells called osteocytes which reside in small cavities known as lacunae. These osteocytes are connected by tiny channel-like structures referred to as canaliculi, which facilitate the transport of nutrients and waste products. Essential to bone structure, Osteons align parallel to the long axis of the bone, aiding in the bone's ability to resist bending or fracturing, especially when stresses are applied in only a few directions.

What are some examples of dishonest behaviors on the job?
Answer:
Copying the work of others, gossip, telling lies about co-workers, info sharing
Explanation:
Dishonest behaviors on the job can be seen in many different forms. The most common one is copying or even stealing the work of others and passing it on as one's own. It is not only dishonest, it breaks the trust between co-workers and may be considered theft and a reason to be fired. Spreading gossip, telling others facts about a person's personal life or simply inventing things to make somebody be seen in a bad light, all these are also dishonorable, dishonest behaviors. Complaining about a person's behavior to the boss without confronting the person in question first can be another example of it.

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.

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.

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.

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.
Thus, the correct answer is option (B).
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.
