Question

what is the structure and function of the nefron

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. 

Answer 2

Heyaaaa...

Nephron - Structural and Functional Unit Of the Kidney.

Here is your answer 》》》》》》》》

_____________________________

STRUCTURE AND SPECIFICATIONS :

# Each kidney is made up of a large number of excretory units called Nephrons.

# The Nephron had a cup shaped bag at its upper end called the Bowman's Capsule. The lower end of the Bowman's Capsule is tube - shaped and it is called as Tubule.

# The Bowman's Capsule and the Tubule together make a Nephron.

# One end of the Tubule is connected to the Bowman's Capsule and its other end is connected to the urine collecting duct of the kidney. The Bowman's Capsule contains a bundle of blood capillaries which is called Glomerulus.

# One end of the Glomerulus is attached to the renal artery which brings the dirty blood containing urea waste into it. The other end of the Glomerulus comes out of Bowman's Capsule as a blood capillary, surrounds Tubule of Nephron and finally joins a renal vein.

__________________________

FUNCTION OF NEPHRON :

# The function of Glomerulus of Nephron is to filter the blood passing through it. Only the small molecules of substances per we in blood like glucose, amino acids, salts, urea and water etc.., pass through the Glomerulus and collect as filtrate in the Bowman's Capsule. The larger molecules like protein and blood cells cannot be passed out through the Glomerulus capillaries and hence remain same in the blood.

# The function of Tubule of Nephron is to allow the selective reabsorption of the useful substances like glucose, amino acids, salts and water into the blood capillaries. But the wage material like Urea remains behind in the Tubule. It does not get reabsorbed into the blood capillaries.

I have attached the magnified picture of Nephron along with the working of it..

And I have attached another picture of kidney to show the location.. But there are lots of Nephrons in the Kidney in those areas..
