Document Summary
Introduction: the main function of the digestive system is to break down organic nutrients so that they can be absorbed into the body, these organic nutrients can be carbohydrates, proteins, fats, water, vitamins, and minerals. Anatomy and basic function: the basic functions of, mouth. Function: the stomach liquefies, mixes, and stores each bolus of food from the meal, this mixture, called chyme, is slowly released into the small intestine, where most of the digestion and absorption takes place. Intrinsic factor helps with the absorption of vitamin b12. Functions: the pancreas produces and secretes the carbohydrate-digesting enzyme amylase, the protein-digesting enzymes trypsin, chymotrypsin, the proteases, and the fat-digesting enzyme lipase, the pancreas also secretes sodium bicarbonate into the duodenum to neutralize the acid from the stomach. It is divided into 3 segments: (1) the duodenum. Human phys module 15 notes the digestive system: like reabsorption in the kidneys, there are very specific mechanisms to transport each molecule into the body.
