alternate name for the gastrointestinal system alimentary canal
alternative name for the gastrointestinal is also know as the digestive tract. digestive system
the body system that incudes the salivary gland, the oral cavity , the teeth the gums, the palate, and the tongue. (pharynx, esophagus, stomach, small and large intestine, and the accesory organ of the liver. The gall bladder and pancreas. gastrointestinal system. It's function is to digest food assort the nutrients into the blood and remove indigested material.
process of swallowing food deglutition
area of the brain that recieves and interprets taste from the tongue gustatory cortex
process of chewing. This is a part of mechanical digestion. mastication
mucous membrane that lines the gastrointestinal system and produce mucus. mucosa
mouth. Hollow area that contains the hard palate soft palate, uvula, tongue, gums and teeth. oral cavity
the hard bone and posterior soft tissue that form the roof of the mouth palate
throat. the passageway for both food and inhaled and exhaled air. pharynx
three pairs of glands(parotid, submandibular, and sublingual) secretes saliva into mouth. Saliva is a watery substance that contains digestive enzymes amylase. salivary glands
large muscles that fill the oral cavity to assist with eating and talking and contains receptors for the sense of taste tongue
fleshy hanging part of the soft palate. Plays role in speech and swallowing, initiates the gag reflex to prevent food from entering the pharynx before the epiglottis closes over the larynx. uvula
small area where the esophagus enters the stomach cardia
partially digests food, saliva, and digestive enzymes in the stomach and small intestine chyme
flexible, muscular tube that moves food from the pharynx to the stomach esophagus
rounded, most superior part of the stomach fundus
muscular ring at the distal end of the esophagus it keeps food in the stomach from going back into the esophagus lower esophageal sphincter
muscular ring that keepschyme in the stomach or opens to let chyme into the duodenum pyloric sphincter
narrowing area of the stomach just before it joins the duodenum. It contains the pyloric sphincter pylorus
deep folds in the gastric mucosa that expands and accomodates the food rugae
organ of digestion between the esophagus and the small intestine. Secretes hydrochloric acid, pepsinoge, and gastrin stomach
cardia, fundus, body and pyloris. secretes intinsic factor needed to absorb vitamin B12 stomach
external opening of the rectum. the external anal sphincter is under voluntary control anus
long, thin pouch on the exteriior wall of the cecum. It does not play a role in digestion. It contains lymphatic tissue and is active in the body's immune response appendix
short pouch-like part of the large intestine. The appendix is attached to the cecums internal wall cecum
longest part of the large intestine it consist of the ascending colon, transverse colon, descending colon and S-shaped sigmoid colon. colon
first part of the small intestine. It secretes hormaone cholecystoknin. Digestion takes place there as well as some absorptin of nutrients and water duodenum
pouches in the wall of the large intestine that expands and accomaodates the bulk of undigested material haustra
third part of the small intestine. It connects to the cecum of the large intestine. Some digestion takes place there. There is apsorption of nutrients and water through the walls of the ileum and into the blood ileum
second part of the small intestine. Digestion takes place there as well as some apsorption of the nutrients and water through the intestinal walls and into the blood. jejunum
Organ of apsorptin between the small intestine and the anus the large intestine includes the cecum, the colon and the rectum and anus. It is also known as the large bowel large intestine
open channel inside a tubular structure such as the esophagus, small intestine, and large intestine lumen
final part of the large intestine. It is a short, straighht segment that lies between the sigmoid colon and the anus. rectum
organ of digestion between the stomach and the large intestine. The deudenum, jejnum, and ileum are the large intestine are the three parts of the small intestine. aka small bowel small intestine
microscopic projections of the mucosa in the small intestine. They produce digestive enzymes such as lactase to break down sugars. They have a large combined surface area to maximize the apsorption of nutrients nutrients into the blood villi
continous cavity within the abdomenn and pelvis that contains the largest organs(viscera) of the gastrointestinal system abdominopelvic cavity
bitter fluid produced by the liver and stored in the gallbladder. It is releasd into the deudenum to digest the fat in foods, It contains the green pigment billiverdin and the yellow pigment billirubin. bile
bile produced by the liver flows through the hepactic ducts to the commomn hepactic duct. It goes into the common bile duct to the deudenum. When that duct is full it goes into the cystic duct and gallbladder. All of thhese form billary tree bile ducts
part of the abdominal aorta where arteries branch of to take blood to the stomach, small intestine, liver, gallbladder, and pancreas celiac trunk
small dark green sac posterior to the liver that stores and concentrates bile. When stimulate by cholecystokinin from the deudenum, it contracts and releases bile into the common bile duct to the deodenum. gallbladder
largest solid organ in the body. It contains hepatocytes that produce bile. liver
thick sheet of peritoneum that supportss the jejenum and ileum mesentery
broad fatty apron of peritoneum. It supports the stomach and protects the small intestine omentum
triangular organ located posterior to the stomach. It secretes digestive enzymes(amylase, lipase, and other enzymes) into the deodenum pancreas
double layer serous membrane that lines the abdominopelvic cavity and surrouinds each gastrointestinal organ. It secretes peritoneal fluid to fill the spaces between the organs peritoneum
process by which digested nutrients move through villi of the small intestine and into the blood apsorption
digestive enzyme in saliva that begins digestion of carbohydrates in the mouth. It is also secreted by the pancreas to finish digestion of carbohydrates in the small intestine amylase
hormones secreted by the deudenum when it receives fatty chyme from the stomach. Cholecystokinin stimulates the gallbladder to release bile and the pancreas to release its digestive enzymes cholecystokinin
process by which undigested materials and water are removed from the body as a bowel movement defecation
process of mechanically and chemically breaking down food into nutrients that can be used by the body digestion
process by which undigested materials and water are eliminated by the body elimination
process in which bile breaks down large fat droplets into smaller droplets emulsification
process that speeds up chemical reactions in the body. Duringchemical digestion, enzymes break the chemical bonds in large food molecules. Enzymes are produced by the salivary glands, stomach, small intestine, and pancreas enzymes
formed, solid waste composed of undigested material, bacteria, and water that is eliminated from the body. aka as stool feces
gas produced by bacteria that inhabit the large intestine flatus
hormone produced by the stomach. It stimulates the release of hydrochloric acid and pepsinogen in the stomach gasttin
strong acids produced by the stomach. It breaks down food, kills microorganisms in food, and converts pepsinogen to pepsin hydrochloric acid
digestive enzyme from villi in the small intestine. It breaks down lactose, the sugar in the milk lactase
digestive enzyme secreted by the pancreas. It breaks down fat globules in the deodenum into fatty acids lipase
digestive enzyme in the stomach that breaks down protein foods into large protein molecules pepsin
inactive substance produced by the stomach that is converted by hydrochloric acid to the digestive enzyme pepsin pepsinogen
