- Explain the kidneys’ role in blood pressure regulation.arrow_forwardWhich scenarios or external factors would cause the parasympathetic nervous system to activate decreased blood pressure?arrow_forwardYou are designing the arterial blood vessels that go to the kidney. The first part of kidney function involves a filtration mechanism that filters blood. To maximize this filtration mechanism, you want to maximize blood flow to the kidney. Using Poiseuille’s Law (on page 1), explain how you would construct the arterial circuit so that blood flow is maximized. Assume that blood viscosity (h) will not be changed.arrow_forward
