the kidney Flashcards
1
Q
two functions of the kidneys
A
excretion of urea
osmoregulation
2
Q
how is urea produced
A
deamination of excess amino acids
- amine group converted to ammonia
- urea in humans
- uric acid in birds
this is nitrogenous waste
keto acid - goes into krebs cycle
3
Q
what is osmoregulation
A
keeping blood water pressure within restricted limits by producing different volumes and concentrations of urine
4
Q
structure of the kidney
A
bowmans capsule
afferent arteriole - glomerulus - efferent arteriole
proximal convoluted tubule
descending limb - loop of henle - ascending limb
distal convoluted tubule
collecting duct
