ANATOMY

Detailed explanation-1: -Blood flows into your kidney through the renal artery. This large blood vessel branches into smaller and smaller blood vessels until the blood reaches the nephrons. In the nephron, your blood is filtered by the tiny blood vessels of the glomeruli and then flows out of your kidney through the renal vein.

Detailed explanation-2: -The correct sequence is as follows: Afferent arteriole, Glomerulus, Efferent arteriole. Renal artery. Secondary capillaries, Renal vein.

Detailed explanation-3: -So, the correct answer is ‘Collecting duct–>Ureter–>Bladder–>Urethra’.

Detailed explanation-4: -The renal artery first divides into segmental arteries, followed by further branching to form interlobar arteries that pass through the renal columns to reach the cortex. The interlobar arteries, in turn, branch into arcuate arteries, cortical radiate arteries, and then into afferent arterioles.
