प्रश्न
What is the role of glomerulus in the kidney?
Advertisements
उत्तर
The glomerulus is a high-pressure network of blood capillaries located within the Bowman’s capsule at the beginning of each nephron. Its primary role is ultrafiltration, acting as a microscopic sieve that filters water, metabolic wastes, and small solute molecules from the blood to form the initial glomerular filtrate, while preventing blood cells and large proteins from passing through.
