Functions of Kidney Flashcards
(25 cards)
Two hormones produced by the kidneys are:
Calcitriol and erythropoietin
The 8 main functions of the Kidney are:
1) excretes waste
2) produces hormones
3) regulates blood glucose levels
4) regulates blood ionic composition
5) regulates blood pH
6) regulates blood volume
7) regulates blood pressure
8) maintains blood osmolarity
conserving or eliminating water in the urine ; This belongs to which of the functions?
Regulation of blood volume
Renin is (a)n
a) amino acid
b) hormone
c) enzyme
d) vitamin
c) an enzyme
The kidneys secrete a variable amount of hydrogen and conserve bicarbonate ions; belongs to which of the functions?
regulation of blood pH
The kidneys produce 2 hormones calcitriol and erythropoietin; which of the functions does this belong to
production of hormones
glutamine is (a)n
a) vitamin
b) amino acids
c) hormone
d) enzyme
b) amino acids
The kidneys use glutamine in gluconeogenesis then release the glucose into the blood to help maintain a normal glucose level; this belongs to which function?
regulation of blood glucose level
The kidney helps regulate the blood level of several ions. The kidney accomplish this task by adjusting the amounts of these ions that are excreted into the urine; this belongs to which function?
regulation of blood ionic composition
The kidney also helps regulate blood pressure by secreting…
the enzyme renin
T/F: An increase in blood volume increases blood pressure and a decrease in blood volume decreases blood pressure
True
T/F: bicarbonate ions are not important buffers of Hydrogen
False
what are some of the nitrogenous wastes excreted in the urine?
Urea, Ammonia, uric acid, creatine, urobilin
The kidney helps to regulate the blood levels of several ions. These ions are
sodium, potassium, calcium, chloride, phosphate
T/F: Calcitriol is an active form Vitamin D
True
Calcitriol helps to regulate…
Calcium Homeostasis
erythropoietin stimulates the production of:
red blood cells
by separately regulating the loss of water and the loss of solutes in the urine; belongs to which of the functions
maintaining blood osmolarity
T/F: The kidney removes waste from the blood and excretes it into the urine
True
The urinary system consists of:
2 kidneys
2 ureter
1 urinary bladder
1 urethra
What function does the Ureter serve?
To transport the urine from the kidney to the urinary bladder
What function does the urinary bladder serve?
storing of the urine until it is ready to leave the body.
What function does the Urethra serve?
expels the urine from the body
T/F: The kidneys does not maintain a relatively constant blood osmolarity
False
