The resistance of the afferent arteriole equals 0.5 mm Hg•min/L and the resistance of the efferent arteriole equals 0.5 mm Hg•min/L. What is the pressure in the glomerulus?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

What would happen if the action of the Na+–K+ pumps was reduced? A)The rate of flow of glucose into the interstitial cells would be increased. B)The direction of flow of glucose would be reversed. C)The rate of flow of glucose into the interstitial cells would be reduced. D)Nothing would differ: the movement of glucose would be the same as before the reversal.arrow_forwardName the gland whose secretion is vasopressin.arrow_forwardWhat is the diagram labeled "B" a representation of?
