Chewing, churning of food in the stomach
Enzymes- from the mouth to the small intestine
(M) Initiates swallowing
(M) Transports food from mouth to stomach through "peristalsis"
(M,C) process food then transport
(M) churning to create a "Bolus"
(C) HCL, pepsin kill bacteria and break down food
creamy paste that forms as the food in the stomach is repeatedly mixed with gastric juices.
first 10 inches of small intestine. Bile and pancreatic juices secreted here.
helps digest fat and is made by the liver and stored in the gallbladder
enzymes to break down food
(M,C) Next 8 feet of small intestine. Food absorption by villi (fingerlike projections of the mucosa) and enzyme action.
(M,C) 12 feet that is the "terminal" portion of the small intestine absorption of food and enzyme action.
(M) Part 1 of the Large Intestine (5ft long)

What is responsible for breaking food molecules into smaller molecules?
"broadcasters", releases chemical messages called hormones into bloodstream
"the messengers", effect the activity or behavior of other parts (target cells) of the body.
"Reception Towers", chemical binding sites on target cells
