Question

structure and function of nephron with di

Answer 1

A nephron is the basic unit of structure in the kidney. A nephron is used separate to water, ions and small molecules from the blood, filter out wastes and toxins, and return needed molecules to the blood. The nephron functions through ultrafiltration. Ultrafiltration occurs when blood pressure forces water and other small molecules through tiny gaps in capillary walls. This substance, lacking the blood cells and large molecules in the bloodstream, is known as an ultrafiltrate. The ultrafiltrate travels through the various loops of the nephron, where water and important molecules are removed, and into a collecting duct which drains into the bladder.

Answer 2

☆ STRUCTURE OF NEPHRON:-

♤ Each nephron is a long - coiled tubule whose one end is cup - shaped called Bowman's capsule while other ends are connected to urine collecting duct of the kidney.

♤ The Bowman's capsule contains a bundle of blood capillaries which is called glomerulus.

☆ FUNCTION OF NEPHRON:-

♤ It is the functional unit of kidney.It filters the uncleaned blood so that waste substances can be removed from the blood.
