Structure of nephron

                 Structure of nephron

1) Glorerucless

2) Bow Man's capsule

3) Proximal Convoculated tubeless (PCT)

4) Loop of Henle

a) Ascending

b) Descending

5) Distil C.T

6) Collective tube

The function of nephron/urine concentration

1) Ultrafiltration

2) Selective Reabsorption

3) Secretion

1) Ultrafiltration

The glomerulus filters the deoxygenated blood into oxygenated blood and transports it back out of the kidney.

2) Selective Reabsorption

The different parts of the nephron absorb different materials.

P.C.T.- 80% water, glucose, salt Ascending loop of Henle- Urine

Vasorecta- Glucose, amino acids

D.C.T- Facilitated absorption of 20%water with the help of hormones.

3) Secretion

Excess waste is secreted out of getting the kidney.

4)Micturition 

The process of throwing urine out of the body through the Urethra is called micturition.

This action is Controlled by Lorain.

Urine

• The human urine is yellow due to Bilruvin secreted by the liver.

• The urine is slightly acidic.

Diabetes Incipidus

When a person frequently passes urine is called diabetes Incipidus.

It is a disease caused due to malfunctioning D.C.T.

Hemodialysis

The artificial method of blood filtration outside the body with the help of a dialysis machine is called haemodialysis. Hemodialysis act as an artificial kidney.
