Which vessel brings blood to the glomerulus for filtration?

The vessel that brings blood to the glomerulus for filtration is the afferent arteriole. This small blood vessel serves as the entry point for blood to the glomerulus, which is a network of capillaries located within the nephron of the kidney. The primary function of the glomerulus is to filter blood, allowing water, ions, and small molecules to pass through while retaining larger molecules, such as proteins, and blood cells within circulation.

The afferent arteriole regulates the amount of blood entering the glomerulus, which is crucial for maintaining filtration pressure and ensuring optimal kidney function. Once blood is filtered, it exits the glomerulus through the efferent arteriole, which is not involved in bringing blood to the glomerulus, but rather carries away the filtered blood. The ureter and urethra are involved in transporting urine from the kidneys to the bladder and from the bladder out of the body, respectively, and do not play a role in bringing blood to the glomerulus.
