the digestive tract includes the mouth esophagus stomach small intestine large intestine rectum and anus the pancreas liver and gallbladder are accessory organs of the digestive tract that have many functions one of which is to produce digestive juices and enzymes that aid in digestion the digestive tract Alters food into readily absorb nutrients and eliminates waste products digestion begins in the mouth saliva moistens the food and Amala an enzyme in saliva begins the process of breaking it down food moves through the esophagus and enters the stomach where digestive enzymes and stomach acid continue breaking it down the
resultant breakdown product called Kim contains carbohydrates small proteins minerals fats vitamins and water Kim exits the stomach and enters the small small intestine the small intestine digests and absorbs each component of Kim pancreatic enzymes eventually break down carbohydrates into several simple sugars called monosaccharides sodium glucose Transporters are responsible for transporting monosaccharide across the intestinal cell membrane into the cell using active transport after transport into the cell glucose Transporters move the monosaccharides out of the cell and eventually into the bloodstream for use by the body enzymes called proteases break down proteins into to amino acids like
carbohydrates amino acids such as glycine are co-transported with sodium ions via the sodium glucose transporter various amino acid Transporters then transfer amino acids into the interstitial fluid where they are available to build proteins needed by the body minerals such as sodium are co-transported with carbohydrates and amino acids liver bile salts emulsify fats then pancreatic and intestinal enzymes digest them into fatty acids and a glyceride bile acid droplets called my cells absorb the the fatty acids and a glyceride as well as any fat soluble vitamins in the Kim and deliver them to the intestinal cell wall
for absorption within the cell the lipids and fat soluble vitamins are packaged into kyom microns which are delivered to the Lacs or lymphatic capillaries in the intestinal villi for transport to the lymphatic system and eventual return to the blood
