Please help me with these questions, more than one answer may be correct for each:1) Which of the following statements are true about the renin-angiotensin-aldosterone axis?
A)
Angiotensin II stimulates production of aldosterone, which increases sodium reabsorption
B)
Renin converts angiotensinogen to angotensin I
C)
Angiotensin II stimulates production of vasopressin, which increases aquaporins in the collecting duct

Vasopressin decreases thirst
E)
Renin lowers GFR
2) The purpose of excretion is to
A)
maintain internal pH
B)
remove harmful substances
C)
maintain plasma volume
D)
maintain osmotic balance
E)
maintain internal solute concentration

- Drugs that increase urine flow (diuretic drugs) are often employed in the treatment of hypertension (high blood pressure) or other disease states.
