Question 4
What effect does adrenaline (epinephrine) have on renal arterioles?
Question 5
Which hormone constricts arterioles to maintain GFR despite low blood pressure?
Question 6
What is the primary function of the glomerulus?
Question 7
Which portion of the nephron is involved in the exchange of ions and water with peritubular capillaries?
Question 8
Which part of the nephron is primarily responsible for filtration of plasma?
Question 9
Which type of natriuretic peptide is secreted by the atria of the heart?
Question 10
How does Angiotensin II affect renal blood flow and GFR?
Question 11

Question 13
At low concentrations, which molecule dilates renal arterioles to increase blood flow?
Question 14
Which part of the renal tubule is involved in the first stage of reabsorbing nutrients and water?
Question 15
