Anatomy QIV:PII

The Digestive System

QuestionAnswer
the food tube which moves from mouth to anus alimentary canal
includes the mouth, pharynx, esophagus, stomach, small intestine, and large intestine alimentary canal
includes the teeth, tongue, gallbladder, salivary glands, liver, and pancreas accessory digestive organs
name for the food ball formed initially by the tongue and teeth bolus
absorption of the nutrients into the blood primarily occurs in the small intestine
absorption of excess water primarily occurs in the large intestine
serous membrane lining the body wall parietal peritoneum
serous membrane surrounding the digestive organs visceral peritoneum
a slit-like potential space between the serous membrane layers peritoneal cavity
means behind the peritoneum-an example of this retroperitoneal, kidneys
innermost layer of tissue in the alimentary canal mucosa
layer external to the mucosa submucosa
layer external to the submucosa muscularis externa
outermost layer of the alimentary canal wall, also the visceral peritoneum serosa
lips formed by what muscle orbicularis oris
cheeks formed by what muscle buccinator
how many deciduous (baby) teeth 20
how many permanent teeth 32
largest of the salivary glands, located near the masseter muscle parotid glands
three pairs of salivary glands parotid, submandibular, sublingual
the site of the beginning of protein digestion stomach
the bolus is turned into chyme in the stomach
this organ secretes pepsin stomach
passages for air and food pharynx
muscular food tube that is a continuation of the pharynx esophagus
part of stomach which prevents backflow of acid and food particles, where food enters the stomach cardiac sphincter
the superior dome-shaped portion of the stomach fundus
the main, large, centralized region of the stomach body
the last region of the stomach before food enters the small intestine pylorus
the lateral or convex curvature of the stomach greater curvature
the medial or concave curvature of the stomach lesser curvature
multiple internal folds of mucosa in the stomach rugae
longest portion of the alimentary canal small intestine
site of most enzymatic digestion and absorption of nutrients into the blood small intestine
the three portions of the small intestine from proximal to distal duodenum, jejunum, ileum
part of the small intestine which receives digestive enzymes from the pancreas and bile from the liver duodenum
Peyer's patches are found in this structure small intestine
Brunner's glands are found in this structure small intestine
main function of this organ is to absorb water and electrolytes into the bloodstream large intestine
most proximal region of the large intestine cecum
most proximal region of the colon portion of the large intestine ascending colon
most distal region of the colon portion of the large intestine sigmoid colon
part of large intestine which descends along the inferior half of the sacrum rectum
the last subdivision of the large intestine/most distal portion of the large intestine anal canal
the bend between the ascending colon and the transverse colon right colic/hepatic flexure
the bend between the transverse and descending colon left colic/hepatic flexure
a gathered segment of the large intestine haustrum
the largest gland in the body liver
the digestive function of the liver bile production
is the liver part of the alimentary canal or is it an accessory digestive organ? accessory digestive organ
stores and concentrates bile gallbladder
the function of bile is to emulsify and breakdown fats
the area of the liver without peritoneum bare area
the ligament which divides the right and left lobes of the liver falciform ligament
structure on the liver which contains the hepatic portal vein porta hepatis
the round ligament, a remnant of a fetal circulatory structure, found on the liver ligamentum teres
remnant of a fetal circulatory structure found in the fissure of the liver ligamentum venosum
this part of the gallbladder converges with the common hepatic duct cystic duct
an heterocrine gland of the digestive system pancreas
exocrine function of the pancreas, delivers ______ to the small intestine pancreatic enzymes
endocrine function of the pancreas, produces ____ and _____ insulin, glucagon
blood sugar regulator produced by pancreas-reduces blood sugar insulin
blood sugar regulator produced by pancreas-increases blood sugar glucagon
where the right and left hepatic duct converge common hepatic duct
the convergence of the common hepatic and cystic duct to the small intestine bile duct (common bile duct)
