Which of these responses is NOT a response consistent with a drop in mean arterial pressure?
increased filtration by the kidneys
increased thirst
secretion of aldosterone
release of renin from the kidneys
increased filtration by the kidneys
Which of the following is NOT one of the ways that angiotensin II increases arterial blood pressure?

release of renin from the kidneys
conversion of angiotensin I into angiotensin II
sympathetic nervous system activity

Why is it important that blood pressure drop to lower levels as it reaches the capillary beds?
because capillaries are fragile and extremely permeable
because capillaries actually need a higher blood pressure for filtration activities
because capillaries depend on the lower pressure to prevent fluid exchange between the capillaries and the tissue fluid
