Final answer:
The blood vessel that directly feeds the glomerulus with blood from the cortical radiate artery is the afferent arteriole.
Step-by-step explanation:
The blood vessel that directly feeds the glomerulus with blood from the cortical radiate artery is the afferent arteriole. This is the branch of the renal arterial system that enters the nephron, forming a capillary network within the glomerulus, enabling filtration of the blood. Following filtration, blood exits the glomerulus through the efferent arteriole, which then forms the peritubular capillary network, interacting with parts of the renal tubule. The veins mirror the pathway of the arteries, with names corresponding to the arterial sections they accompany.
