8.3 Stomach to Small Intestine stomach-thick walled, j-shaped organ that stores food rugae-fold that disappears as the stomach fills up gastric glands-glands that produce gastric juice pepsin-digests protein small intestine-long intestine that contains enzymes to digest all kinds of food duodenum-first 25 -cm of the small intestine bile-it emulsifies fat lipaseit hydrolyzes to glycerol villus-fingerlike projections in the small intestine lacteal-small lymphatic capillary lactose intolerance-cannot digest lactose

(1) What are the functions of the stomach? It stores food and initiates the digestion of protein and controls the movement of chyme into the small intestine

(2) What are the structures of the stomach that perform these functions and describe their role. The rugae, the gastric glands and the mucosa.

(3) What are the functions of the small intestine? The enzymes to digest all types of foods and it absorbs molecules into the walls

(4) What are the structures of the small intestine that perform these functions and describe their role? The enzymes that digest everything

8.4 Three Accessory Organs and Regulation of Secretions pancreas-fish shaped, spongy, grayish pink organ that stretches across the back of the abdomen behind the stomach pancreatic amylase-digests starch trypsin-digests protein lipase-digests fat hormone-substance produced by one set of cells that affects another set of cells. Liver-Makes plasma proteins and regulates the quantity of cholesterol Bile-it emulsifies fat Bladder-where bile is stored

(5) What are the three main accessory organs that assist with the digestive process? Describe how each contributes to the digestion of food. Pancreas-produces pancreatic juice, it digests starch, protein, and fat Bile-Has yellowish green color Gallbladder-pear shaped organ below the liver Gallstones-Formed when liquid in the gallbladder hardens

(6) How are digestive secretions regulated in the body? Hormones regulate the digestive secretions

8.5 The Large Intestine and Defecation large intestine-absorbs water and does not produce digestive enzymes cecum-lies below the junction with the small intestine vermiform appendix-Small projection in the large intestine colon-just below the liver and the stomach

(7) What are the different parts of the large intestine? Cecum Vermiform appendix Colon Rectum Anus

(8) What is the function of the large intestine? It serves to absorb water and prevents dehydration. It does not produce any digestive enzymes.
