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.
Explanation:
a. Nasal cavity: the epithelium in this zone is meant to provide a physical barrier to the invasion of microorganism or particles, it also secretes and remove mucus and foreign particles, these epithelial cells are also involved in the igE producing process (perpetuating allergic responses. <em>The nose is the first barrier to the air that enters our body, that's why the epithelial cells in this zone focus in filtering foreign particles. </em>
b. Bronchiole: epithelium is ciliated and no ciliated, it becomes cuboidal in smaller passages as it continues to branch. The no ciliated cells, also known as club cells are the ones that produce surfactant. <em>Since bronchioles are passages to direct the air to the alveoles epithelial cells in this zone have adapted to go from larger branches to smaller ones to reach the alveoli. </em>
c. Alveolus: it's composed of two types of cells, type one, that constitute the air-blood barrier and type two, cells that produce surfactant to reduce surface tension to keep the alveolus shape when breathing.<em> Since alveoli's function is to allows oxygen/carbon dioxide to move between bloodstream the epithelial cells in this organ evolved to cover this job.</em>

Fatty acids are insoluble in water and must be combined with bile to generate water-soluble compounds. Lipase is an enzyme found in the pancreas. Amylase is a starch digesting enzyme found in saliva and pancreatic juice. Despite the fact that cholesterol is synthesized in the liver and stored in the gallbladder, it is not a component of bile that emulsifies fats.
Bile is a fluid that the liver produces and stores in the gallbladder. Bile aids in digestion. It converts fats into fatty acids, which are then absorbed by the digestive tract. Bile is mostly composed of cholesterol.
Bile is required for fat digestion as well as the elimination of worn-out red blood cells and certain toxins from the body. Bile is made in the liver and stored in the gallbladder.

Answer:
The small intestine is the body's most important digestive organ. It performs both chemical and mechanical digestion and is the main site of absorption.
Explanation:
The small intestine measures about 20 feet, and is divided into duodenum, jejunum and ileum. 90% of absorption of nutrients and minerals take place in the small intestine, and the remaining 10% in the stomach and large intestine.
