Through which structure does blood exit the glomerulus?

Blood exits the glomerulus through the efferent arteriole. The glomerulus is a network of capillaries located in the kidney that plays a crucial role in the filtration of blood to form urine. When blood enters the glomerulus, it is delivered via the afferent arteriole, which supplies blood to the capillary network. After filtration, the remaining blood, which has been processed for waste and excess fluid, exits the glomerulus through the efferent arteriole. This vessel carries the filtered blood away from the glomerulus and leads to other parts of the nephron, where further processing occurs.

The renal vein is responsible for carrying blood away from the kidneys, but it is not directly involved in the exit from the glomerulus. Bowman's capsule, on the other hand, is the structure that collects the filtrate produced in the glomerulus but does not carry blood itself. The proper function of the efferent arteriole is essential for maintaining the pressure needed for continued filtration in the nephron, thereby playing a critical role in kidney function.
