In the nephron, if the afferent arteriole dilates and the efferent arteriole con- stricts, which of the following would be true? A. The glomerular fi ltration rate would decrease. B. The pressure in the glomerulus will decrease. C. The absorption of sodium and chloride ions form the fi ltrate would increase. D. Before these events, the granular cells would have released renin.
Option D. The granular cells of the afferent arteriole respond to low blood pressure via way of means of releasing renin. As a result, angiotensin II might formed which reasons systemic vasoconstriction, which will increase blood pressure, which dilates the afferent arteriole and will increase glomerular filtration rate.
