Digestive system
Definition
Breaks down what we have ingested; converts food into chemicals that the body can use; excretes the excess waste
Begins at the mouth, which mechanically breaks down food through chewing; saliva is released while we chew, which contains enzymes which further help break down food
Esophagus uses peristalsis to move food into the stomach; stomach prepares by releasing gastric juices (hydrochloric acid and pepsin)
The stomach churns the food for 3-4 hours and releases mucus to protect the stomach from the acid
The stomach uses peristalsis to push food into the small intestine (duodenum), where the acidic mixture is made more alkaline; enzymes break down carbs, fat, and proteins further; absorption increases- membrane with capillaries allows nutrients (amino acids) to pass into the blood
Leftover material passes into the large intestine, where remaining water is absorbed, and the leftover material is released from the rectum as waste
Term
