Describe the process of urine formation of kidneys
Answers
Answer:
The functional unit of kidney is called nephron.
A nephron is composed of a tuft of blood capillaries and highly coiled ducts. The tuft of blood capillaries is surrounded by a cup-shaped structure; called Bowman’s capsule.
Waste material from blood are filtered out of the capillaries and they go through the wall of Bowman’s capsule.
After that, the waste material and water pass through the ducts. When the mixture of water and other materials move through the duct, some materials and water are reabsorbed. This depends on excess amount of water present in the body.
After reabsorption of water and other material, urine becomes concentrated. This then goes to the collecting duct.
Urine from collecting ducts moves through ureter into the urinary bladder. From the urinary bladder, urine is expelled from the body as and when required.
