Question

Which part of the nephron is primarily responsible for filtration of blood?

• A. Loop of Henle
• B. Proximal convoluted tubule
• C. Bowman's capsule
• D. Collecting duct

Hint:

Bowman's capsule = Blood filtration. It is the first step in urine formation!

Answer 1

The Correct Option is C

The Bowman's capsule is a cup-shaped structure that surrounds a network of capillaries called the glomerulus. Filtration begins when blood enters the glomerulus under high pressure. This high pressure forces water, small solutes (like salts, glucose, urea, etc.), and other substances through the walls of the capillaries into the Bowman's capsule. This process forms the initial filtrate, which is then processed further as it travels through the renal tubules of the nephron. Larger molecules such as proteins and blood cells are too large to pass through the filtration membrane and remain in the bloodstream.
