​Given below is the diagram of a nephron. Select the option with the correct labelling for a, b, c and d parts.

Correct option is B

​The correct answer is (b) a - Branch of renal artery, b - Glomerulus, c - Bowman's capsule, d - Branch of renal vein

Explanation: Let us have a look at the parts:-

a- Branch of renal artery- The renal artery is responsible for supplying oxygenated blood to the kidneys. The renal artery branches into smaller vessels within the kidney to ensure the proper delivery of blood.

b - Glomerulus- The glomerulus is a network of tiny blood vessels (capillaries) located within the kidney, specifically in the nephron, which is the functional unit of the kidney. The primary function of the glomerulus is to filter blood as the first step in the process of urine formation.

c - Bowman's capsule-The Bowman’s capsule (also called the glomerular capsule) is a crucial structure in the nephron of the kidney, located around the glomerulus. It plays a key role in the process of urine formation by facilitating the filtration of blood.

d - Branch of renal vein- The renal vein is responsible for carrying deoxygenated blood away from the kidneys and back to the circulatory system, specifically to the inferior vena cava, which then returns the blood to the heart. While the renal vein itself doesn't have branches in the same way as arteries do, it does collect blood from various smaller vessels within the kidney.
