Abdominal + Oral Cavity

function of the diaphragm?

inhalation and exhalation

function of the liver?

filters blood, breaks down poisonous substances and produces bile for digestion

function of gall bladder?

stores and concentrates bile

function of the greater omentum?

protective barrier for intestines, stores fat, and activates immune responses

function of stomach?

breaks down/digests food by producing enzymes and acids

function of small intestine?

absorption and digestion of nutrients from food

function of large intestine?

absorbs water/fluids from food to form solid waste for excretion through anus

function of pancreas?

produces digestive enzymes and hormones like insulin to regulate blood sugar levels

function of spleen?

filters blood, controls level of red blood cells, and helps fight infections

function of peritoneum?

lines abdominal cavity and protects it from infections and pathogens; also provides a pathway for nerves and blood vessels

name the lobes of the liver

right medial, right lateral, left medial, left lateral, caudate

A?

lesser curvature

B?

cardiac sphincter

C?

fundus

F?

greater curvature

E?

ruggae

H?

pyloric sphincter

Green arrow?

hard palate

Blue arrow?

soft palate

what vessels run through the diaphragm?

aorta, posterior vena cava, esophagus

what two ducts come together to form the common bile duct? from which organ?

hepatic and cystic, from gall bladder

name each region of the large intestine

cecum, ascending, transverse, descending, rectum, anus

name each region of the small intestine

duodenum, jejunum, ileum

what vessels run through the mesentery?

blood vessels, lymphatic vessels, lymph nodes, adipose tissue

function of villi?

increases surface area in the small intestine for greater rate of absorption of nutrients

function of cardiac sphincter?

prevents stomach acid from traveling up the esophagus

where does the pancreatic duct enter?

duodenum

function of mesentery?

suspends intestines within the abdomen, and controls immune responses

function of ruggae?

allows for expansion of stomach b/c cats are opportunistic feeders

function of vestibule?

contains food during chewing

function of tongue?

swallowing, pushing food back to esophagus, speech (humans)

how many ridges in hard palate?

8

function of hard/soft palates?

aids in swallowing, separates nasal and oral cavities

what oral structure do humans have that cats don’t?

uvula

function of filiform papillae?

creates a rough texture on tongue to help with food movement

function of spiny papillae?

grooming fur

function of epiglottis?

prevents food from traveling down trachea

function of trachea?

allows airflow to lungs

function of esophagus?

transport food from mouth to stomach

explain the function of the epiglottis when the cat eats and swallows food

as the tongue pushes food down, the larynx moves up and causes the epiglottis to flap over the trachea and prevent food from entering. the trachea then compresses as food travels behind it into the esophagus.

what allows the esophagus to push food forward?

peristalsis

function of lingua finellum?

holds tongue down to bottom of the mouth

function of incisors?

snipping and cutting

function of canines?

ripping and tearing flesh

function of premolars?

crushing (small in cats)

function of molars?

grinding/chewing (pointy in cats, flatter in omni/herbivores)

how many sets of teeth does a cat have in its lifetime?

how many teeth are in the first set?

26

how many are in the permanent set? lower jaw? upper jaw?

30. 14 lower, 16 upper

how many incisors do cats have?

12

how many canines do cats have?

4

how many premolars do cats have?

10

how many molars do cats have?

4

how many pairs of salivary glands are there?

5

function of cystic duct?

transports bile from gallbladder to small intestine

function of hepatic duct?

transports bile from liver, joins with cystic duct

function of pancreatic duct?

transports pancreatic/digestive fluid to duodenum

function of common bile duct?

carries bile from liver & gallbladder, through the pancreas, into small intestine

function of mandible?

holds jaw together
