NEET PG DENTAL EXAM

Detailed explanation-1: -As blood flows into each nephron, it enters a cluster of tiny blood vessels-the glomerulus. The thin walls of the glomerulus allow smaller molecules, wastes, and fluid-mostly water-to pass into the tubule.

Detailed explanation-2: -The blood flows under a certain pressure in the renal artery. This pressure helps in filtering the blood through the thin walls of the capillaries forming a network in a nephron. Blood cells and proteins remain in the capillaries while urea, wastes and a large amount of water get filtered out into the nephron.

Detailed explanation-3: -Each nephron in the mammalian kidney is a long tubule, or extremely fine tube, about 30–55 mm (1.2–2.2 inches) long. At one end this tube is closed, expanded, and folded into a double-walled cuplike structure.

Detailed explanation-4: -A glomerulus is the network of capillaries that resides in the Bowman’s capsule that functions as a filtration unit of kidney.
