Digestive Vocab Absorption diffusion of nutrients through intestinal microvilli for blood Cephalic phase the brain prepares to absorb food and the saliva production increases Chemical Digestion Chemical breakdown of food from enzymes or other chemicals Crypts of Lieberkuhn tubular glands of the intestinal mucous membrane Deglutition swallowing Faiciform ligament ligament that attaches the liver to the anterior body wall Gastric Lipase acidic lipid enzyme in mucous in the stomach Gastric Phase matter in stomach sends signals to medulla oblongata and back to stomach to stimulate gastric glands Greater omentum fold of visceral peritoneum that hangs down from the stomach Intestinal phase gastric secretion in stomach as a result of food stimulation in intestine Lactase enzyme that hydrolyses lactose Lamina propria moist mucous connective tissue linings in tubes of the body beneath epithelium Lesser Omentum double layer of peritoneum that extends from the liver to the lesser curvature of the stomach and the start of the duodenum Lingual Lipase enzyme that catalyzes first digestion of dietary lipid MALT mucosa associated lymphoid tissue small concentrations of lymph tissue in GI tract Maltase enzyme that breaks down maltose to glucose Mechanical Digestion physical breakdown of food chewing Mesentery double layer of peritoneum that suspends jejunum and ileum from the posterior wall Mesocolon the peritoneal process attaching the colon to the abdominal wall Muscularis the smooth muscular layer of the wall of various contractile organs Nucleases enzyme that digests out nucleic acids Pancreatic amylase enzyme that catalyzes the hydrolysis of starch into simpler compounds from thyroid breast of the abdomen the pancreas Pancreatic Lipase enzyme that catalyzes the breakdown of fats secreted by the pancreas Papillae small nipple like projections Pepsin enzyme released by chief cells in stomach that degrades proteins to peptides Digestive Vocab Peristalsis radially symmetrical contraction and relaxation of muscles to push something down a muscular tube Serosa a serous membrane Salivary amylase enzyme that breaks down starch in the saliva Submucosa dense connective tissue that binds mucosa to underlying smooth muscle in the GI tract Sucrase enzymes that catalyze sucrose Trypsin serine protease in the digestive system that hydrolyzes proteins
