Which structure is part of a nephron?

• A. Kidney
• B. Ureter
• C. Bowman's Capsule
• D. Bladder

Answer: (C)

The nephron is the kidney’s functional unit responsible for filtering blood and forming urine. Each nephron begins with the renal corpuscle, which includes the glomerulus and Bowman's capsule. The glomerulus filters plasma, and the resulting filtrate is collected by Bowman's capsule before moving into the tubular parts of the nephron for processing into urine. Among the options, Bowman's capsule is the structure that is part of a nephron because it forms the initial collecting sac around the glomerulus and starts the filtrate collection. The kidney is the organ that contains many nephrons, the ureter transports urine to the bladder, and the bladder stores urine.
