found in SMALL INTESTINE; the ridged texture facing the lumen which maximizes absorption of nutrients
Term
cecum
Definition
found in LARGE INTESTINE; the end which connects to the ileum and the ascending colon
Term
appendix
Definition
found in LARGE INTESTINE; while not found on the cat, this is a feature of human anatomy, it connects to the cecum

found in LIVER: the middle portion in feline anatomy
Term
caudate lobe
Definition
found in LIVER: most inferior portion on right side in feline anatomy
Term
gallbladder
Definition
not in liver itself, but adjoins to it, a green organ which releases excretions through ducts to aid digestion
Term
hepatic ducts
Definition
greenish ducts that transport material from the liver
Term
cystic duct
Definition
duct that transports material from the gallbladder
Term
common bile duct
Definition
transports material, fusion of hepatic ducts and the cystic duct
Term

Term
visceral pericardium
Definition
found in HEART; synonymous with epicardium
Term
apex
Definition
found in HEART; portion that points down and left
Term
myocardium
Definition
found in HEART; the tissue that comprises the majority of the heart mass
Term
