Saliva
Secretionog the salivary glands; contains, water, electrolytes, mucus, and ptyalin
Chyme
Partially digested food that is mashed into a pastelike consistency in the stomach.
Intrinsic Factor
A deficiency of this substance leads to pernicious anemia.
Hydrochloric Acic HCl
A substance that is secreted by the lower parietal cells of the stomach: lowers the gastric pH.
Bile
This is a substance produced by the liver and stored in the bile. It is also an emulsifying agent.
Amylase (s)
Enzyme found inthe saliva; also called ptyalin. Enzymes that digest carbohydrates to disaccharides.
Proteases
Enzymes that digest proteins in to small peptides and amino acids. Classification o fpepsin, trypsin, chymotrypsin, and enterokinase.
Disaccharidases
sucrase, maltase, lactase
Chyle
Milky white lymph caused by fat digestion
Lipases
Enzymes that digest proteins into small peptides and amino acids
Secretin
A hormone secreted by the walls of the duodenum stimulates the pancreas to secrete a bicarbonate-rich substance
cholecystokinin CCK
A hormone secreted by the walls of the duodenum; stimulates the pancreas to secrete an enzyme-rich substance, and causes the gallbladder to contract and eject bile into the common bile duct.
Gastric juice
Secretion of the glands of the stomach; contains HCl, intrinsic factor, water, electrolytes, and digestive enzymes.
Liver
This organ produces bile and secretes it into the hepatic bile ducts, stores many of the fat soluble vitamins, recieves blood from the portal vein, is the home of the phaocytic Kupffer cells, and synthesizes most of the plasma proteins, including the clotting factors.
Epiglottis
The structure that directs food and water away from the larynx into the espohagus
Liver
This organ converts excess glucose into glycogen for storage and use in the regulation of blood sugar, is the chief organ of drug detoxification, and contains enzymes for urea acid sythesis.
Esophagus
The food tube; carries food from the pharynx to the stomach
Small intestine
The common bile duct empties bile into this structure
Small Intestin
Most digestion and absorption occur within this structure
Small Intestine
The inner lining of this structure is characterized by villi and microvilli; brush border cells
small intestine
divisions include the duodenum, jejunum, and ileum
small intestine
relaxation of the sphincter of Oddi allows bile and pancreatic enzymes to enter this structure.
Small Intestine
The walls of this structure secrete CCK, disaccharidases
Small Intestine
The pylorus connects the stomach with this structure. peristalsis is pendulum like in this organ.
Gallbladder
Pear shaped sac that attaches to the underside of the liver; concentrates and stores bile.
Gallbladder
Organ that is connected to the common bile duct by the cystic duct
Stomach
The parietal cells of this organ secrete hydrochloric acis and intrinsic factor
Stomach
Organ that is divided into the fundus,body, and pylorus
Stomach
The primary function of this organ is to deliver chyme to the duodenum at the proper rate.
Stomach
The walls of this organ are thrown into folds call rugae. This organ contains mucus cells, parietal cells, anc chief cells.
Stomach
Landmarks of this organ include the greater and lesser curvature.
Salivary Glands
Parotid, sublingual, and submandibular.
Salivary Glands
An inflammation of one of these structures is called mumps.
Large Intestine
Divisions include the cecum, colon, retum, and anal canal.
Large Intestine
This structure has bends or curves called the hepatic flexure and the splenic flexure
Large Intestine
A colostomy is a surgical procedeure performed on this structure.
Large Intestine
The appendix is attatched to this structure
Large Intestine
Flatus, feces, and defecation are most related to this structure.
Pancreas
Organ that responds to CCK by secreting amylases, proteases, (including trypsin), and lipases
Pancreas
Organ that decretes the most potent digestive enzymes
Pancreas
Organ that responds to secretin by the secretion of bicarbonate, an alkaline secretion,
Pancreas
Organ that secretes insulin, glucagon, trypsin, and bicarbonate-rich secretion.
Buccal cavity
Part of the mouth or oral cavity.
