Document Summary

Gut is the largest endocrine organ in the body. It contains within its wall a nervous system that functions independently of the central nervous system. Gut receives over 1/3 of total cardiac output so it influences cardiovascular system. And effect on electrolytes thus influences respiratory and renal system. Look at first function = secretion look at most of all secretory organs: salivary glands 3 pairs of salivary glands (parotid, submandibular, sublingual- major). Salivary output is large 1l to 1. 5l most during daytime. They are primarily digestive glands and since we eat during daylight hours. What we learn is in most mammals (humans). Salivary output in human and the composition is different than a rodent or a cat or dog, etc. They adapt to the diet: each juice coming from eat kind of salivary gland is different, converging duct system. What it means is that you start with in the gland, thousands and millions of them that drain into many ducts.
