Question

can you please explain a structure of nephron​

Answer 1

Answer:

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

Nephron is the filtration unit of kidney.ù

STRUCTURE OF NEPHRON

each nephron consists of three parts

1) malpighian body

2)loop of henle

3) collecting duct.

MALPIGHIAN BODY:

it consists of two parts

:bowman's capsule

: glomerulus

BOWMAN'S CAPSULE

the upper part of nephron is cup- shaped called bowman's capsule. it has glomerulus in its cavity.

GLOMERULUS :

it is a cluster of branches which is present in the cavity of nephron. it is formed by a branch of renal artery called afferent arteriole.

the blood carried away from the glomerulus by a small vessels called efferent arteriole. the efferent vessel from two types of capillaries one type of capillaries are called peritubular and other capillaries called vasa recta.

LOOP OF HENLE

the proximal convoluted tube opens into U shaped structure. it passes down into medulla where it bends back and runs up again into the cortex. the loop this formed is known as the loop of henle.

it consists of two limbs descending and ascending limbs.it check the concentration of urine.

COLLECTING DUCT

when tubule reaches the cortex it again becomes convoluted and then passesinto straight part called collecting tubule. many collecting tubules join to form the discharging tubules which finally open at the apex of pyramids. they lead into pelvis which is the expended anterior part of the ureter lying within kidney .
