WebAfferent arteriole constriction leads to reduced inflow into the glomerulus and thus decreased sodium reabsorption from the filtrate. This mechanism helps to conserve sodium and water during times of increased need for these substances (e.g., when facing environmental dehydration or after a large meal).
