Sup Everybody
In class we took notes here are tha main ideas. The food goes through the one way tube called the ailementary canal. It starts with the mouth where mechanical digestion (teeth) and chemical digestion (Saliva, contains enzyme Salivary Amylase) break food down. It then goes to the esophagus, which connect the pharynx (throat) to the stomach. It enters stomach past a Sphincter, w
hich closes to keep food and stomach acid from going back into esophagus. The stomach is a muscular sace lined with mucus that expands and contracts to perform mechanical digestion. It also uses chemical digestion by activating pepsin that breaks down proteins. Nex is the small intestine beginning with the duodenum, Here carbs, lipids and everything else is digested here and nutrients are absorbed. The SI is lined with Villi which increase surface area. In the large intestine water and indigestible junk is absorbed, bacteria absorbs the vitamin K in the food and you are keft with FECES. The other structures involved that arent places the food travels are the liver which makes bile qhich emulsifies fat, gall bladder which stores bile, and pancreas that makes enzymes.
