tongue
consists of skeletal muscle
provides movement for food mastication
directs food to pharynx for swallowing
mouth
opening through which food passes into the body
breaks food into small particles by mastication
palate
separates nasal cavity from oral cavity
soft palate
posterior portion, not supported by bone
hard palate
anterior portion, supported by bone
uvula
soft v-shaped structure that extends from soft palate, directs food to throat
pharynx, throat
performs swallowing action that passes food from the mouth to the esophagus
esophagus
10in tube that is passageway for food extending from pharynx to stomach
peristalsis begins here
stomach
j-shaped sac that mixes and stores food
secretes chems for digestion
cardia
area around the opening of the esophagus
fundus
uppermost domed portion of the stomach
body
central portion of the stomach
antrum
lower portion of the stomach
pylorus
portion of stomach that connects to small intestine
pyloric sphincter
ring of muscle that guards the opening between the stomach and duodenum
small intestine
20ft canal extending from pyloric sphincter
digestion completed
absorption, through villi
duodenum
first 10-12in of SI
jejunum
second portion of the small intestine, 8ft long
ileum
3rd portion of SI, 11ft long, connects with the large intestine
large intestine
canal, 5ft, extends from ileum to anus
absorption, elimination
cecum
blind u-shaped pouch that is the first portion of LI
colon
next portion of LI
divided in 4 parts: ascending, transverse, descending, sigmoid
rectum
remaining portion of LI, 8-10in, sigmoid colon to anus
anus
sphincter muscle at end of digestive tract
salivary glands
produce saliva
liver
produces bile
bile ducts
passageways that carry bile
hepatic-from liver
cystic-from gallbladder
common-to duodenum
gallbladder
small, saclike structure that stores bile
pancreas
produces pancreatic juice
secretes insulin
