A

albumin

41

what two body systems work together to maintain acid-base balance in the body

A

respiratory and renal

46
Q

name 4 chemical analyses or tests that are used to evaluate liver function

A

ALT, AST, iditol dehydrogenase, ALP, GGT, Bilirubin, bile acids, glutamate glutamyltransferase

47

skeletal muscle

50
Q

what color change/condition is associated with elevated bilirubin
