A patient with glomerulonephritis may be prescribed ACE inhibitors. What would an ACE inhibitor ultimately do?

• Inhibits the conversion of Angiotensin I to Angiotensin II

• Increases blood pressure

• Both ‘A’ and ‘B’

Renin ultimately stimulates the activation of Angiotensin II.  Which of the following is NOT a function of Angiotensin II?

• Increases peripheral vasoconstriction

• Stimulates secretion of aldosterone

• Stimulates thirst

• All of the above are functions of Angiotensin II

During period of strenuous exercise, sympathetic activation causes the blood flow to:

• Decrease to skin and skeletal muscles; increase to kidneys

• Cause increase in GFR

• Increase to skin and skeletal muscles; decrease to kidneys

• Be shunted toward the kidneys

Most water moves out of the nephron loop in the:

• Descending portion

Which of the two nephrons is more responsible for concentrating the urine?
