Question

3. What is the approximate length of small intestine ?
4. What is the function of mucous secreted by the stomach?​

Answer 1

3.Although the small intestine is narrower than the large intestine, it is actually the longest section of your digestive tube, measuring about 22 feet (or seven meters) on average, or three-and-a-half times the length of your body.
4. Gastric mucus is a gel-mucous barrier secreted by epithelial cells and glandular cells in the stomach wall. It acts as part of a barrier that protects the stomach wall from the acid and digestive enzymes within the stomach lumen.

Answer 2

Answer:

1) about 22 feet (or seven meters) on average, or three-and-a-half times the length of your body.

2) Gastric mucus is a glycoprotein that serves two purposes: the lubrication of food masses in order to facilitate movement within the stomach and the formation of a protective layer over the lining epithelium of the stomach cavity.
