MICROANATOMY

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 nephron is the minute or microscopic structural and functional unit of the kidney. It is composed of a renal corpuscle and a renal tubule. The renal corpuscle consists of a tuft of capillaries called a glomerulus and a cup-shaped structure called Bowman’s capsule. The renal tubule extends from the capsule.

Detailed explanation-3: -A glomerulus is the network of capillaries that resides in the Bowman’s capsule that functions as a filtration unit of kidney.

Detailed explanation-4: -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.
