ANATOMY

Detailed explanation-1: -[18] Once blood passes through the glomerular capillaries, it exits the glomerulus through the efferent arteriole. From the efferent arteriole, blood enters a second capillary network, the peritubular capillaries, before exiting the kidney through the renal vein and ultimately entering the inferior vena cava.

Detailed explanation-2: -The clean blood leaves the nephron through the efferent arterioles and joins larger vessels to return to the body. The waste and water travel through the hollow tubules of the nephron to form urine.

Detailed explanation-3: -The blood enters the glomerulus through the afferent arteriole and the blood within the waste diffuse through the glomerular capillaries and the filtered blood leaves through the efferent arteriole.

Detailed explanation-4: -Answer and Explanation: The glomerulus is a bundle of specialized capillaries within the nephron that functions as the filtration unit of the kidney. The afferent arteriole moves blood in the direction toward the glomerulus and the efferent arteriole moves blood in the direction away from the glomerulus.

Detailed explanation-5: -Therefore, afferent arterioles contain blood with nitrogenous wastes whereas efferent arterioles contain filtered blood.
