Digestive

a continuous coiled hollow muscular tube that winds through the ventral body cavity from mouth to anus

is a fleshy finger like projection of the soft palate which dongles from the posterior edge of the soft palate

a fold of mucous membrane secures the tongue to the floor of the mouth and limits its posterior movements

occupies the floor of the mouth

the space between the lips and the chicks externally and the teeth and gums internally is the

runs from the pharynx to the diaphragm to the stomach about 25 cm long and essentially a passageway that conducts food by peristalsis to the stomach

it is soft connective tissue containing blood vessels nerve endings mucosa associated lymphoid tissue and the lymphatic vessels

is a muscle layer typically made up of an inner circular layer and an outer longitudinal layer of smooth muscle cells

runs from the pharynx to the diaphragm to the stomach

is the innermost layer a moist mucous membrane that lines the hollow cavity or lumen of the organ

is formed when two layers of peritoneum are fused together routes for nerves blood vessels and lymphatic vessels are found between the layers

what are the two important intrinsic nerve plexuses in the alimentary canal wall

is the expanded part of the stomach lateral to the cordial region

is the expanded part of the stomach lateral to the cardial region

a double layer of peritoneum extends from the liver to the lesser curvature of the stomach.

another extension of the peritoneum that drips downward and covers the abdominal organs like a lazy apron before attaching to the posterior body wall

acts as a temporary storage tank for food as well as a site for food breakdown

produce inactive protein digesting enzymes mostly pepsinogen

a substance needed for absorption of vitamin b12 in the small intestine

produce corrosive hydrochloric acid which makes the stomach contents acidic and activates the enzymes as in the conversion of pepsinogen to pepsin

produce local hormones such as gastrin that are important in regulating the digestive activities of the stomach

hormone that stimulates release of gastric juice and stimulates stomach emptying

stimulates gastric secretion and emptying

activate parietal cells to secrete hydrochloric acid

hormone that inhibits secretion of gastric juice and pancreatic juice and inhibits emptying of stomach and gallbladder

hormone that inhibits gastric motility and gastric gland secretion

hormone that increases bile output by liver

hormone that inhibits gastric motility and gastric gland secretion

hormones that increases output of enzyme which pancreatic juice

hormone that stimulates gallbladder to expel stored by

hormone that relaxes sphincter of duodenal papilla to allow bile and pancreatic juice to enter the duodenum

hormone that inhibits secretion of gastric juice and stimulates insulin release

after food has been processed in the stomach and the thick like heavy cream and is called

it protects the stomach wall from being digested

what are the three subdivision of small intestine

what are the three structures in the small intestine that increase the absorptive surface area tremendously

are finger like projections of the mucosa that gives it a velvety appearance and feel much like the soft nap of a towel

are tiny projections of the plasma membranes of the mucosa cells that give the cell surface of fuzzy appearance sometimes referred to as the brush border

they form an internal corkscrew slide to increase surface area and force chyme to travel slowly through the small intestines of nutrients can be absorbed efficiently

controls the movement of chyme into the small intestine from the stomach and prevents the small intestine from being overwhelmed

it is the exposed part of the tooth above the gingiva or gum

a ceramic like substance a thick as a dime that directly bears the force of chewing it is the hardest substance in the body and is fairly brittle because it is heavily mineralized with calcium salt
