Question

12 multiple choice 2 points reduction of filtration rate and buildup of waste is an indication of kidney failure. which of the following is the most likely contribu aquaporins not opening in the collecting duct reduction of flow through the afferent arteriole release of angiotensin reabsorption of glucose

Explanation:

The afferent arteriole supplies blood to the glomerulus where filtration occurs. A reduction in flow through the afferent arteriole would decrease the amount of blood reaching the glomerulus, leading to a reduction in the filtration rate and subsequent waste - buildup, which are signs of kidney failure. Aquaporins in the collecting duct are mainly related to water reabsorption, angiotensin release is part of the renin - angiotensin - aldosterone system for blood pressure regulation and not directly related to the initial reduction of filtration rate, and glucose reabsorption is a normal process in the proximal convoluted tubule and not a cause of reduced filtration rate and waste - buildup.

Answer:

B. Reduction of flow through the afferent arteriole
