11

enzymes that break down sugars

Disaccharidases

12

A saclike organ located on the lower surface of the liver that acts as a reservoir for bile

Gallbladder

13

System composed of structures and organs involved in the consumption, digestion, and elimination of food; also called the digestive system or gastrointestinal tract

Gastrointestinal (GI) System

14

Cells that produce a protective mucous lining

Goblet Cells

15

An acid produced by parietal cells in the stomach that aids in digestion

Hydrochloric Acid

16

The chemical substance produced by parietal cells that is important in the adsorption of vitamin B12

Intrinsic Factor

Chewing Food

Mechanical Digestion

24

Parts of the peritoneum that hold the abdominal organs in place and provide a passageway for blood vessels and nerves to the organ

Mesenteries

25

The motion of substances through the digestive tract

Motility

26

An elongated organ located in the upper left quadrant within the C-shaped loop of the small intestine, it secretes digestive enzyme and the hormones insulin, it secretes digestive enzymes and the hormones insulin and glucagon

Pancreas

27

The duct through which digestive enzymes pass on their way through the common hepatic duct on the duodenum at the ampulla of vater

Pancreatic Duct
