Question

Explain the role of glomerulus of nephron in the formation of urine.

Answer 1

Glomerulus:

1. The functional unit of the kidney is the nephron.
2. It consists of a glomerulus and Bowman's capsule which are located in the cortex and filter the blood.
3. The glomerulus is a network of capillaries where the blood filtration takes place.
4. As blood flows through the glomerulus, water and solutes from the capillaries are pushed into the capsule as a result of blood pressure through a filtration membrane for urine formation.
5. The glomerular filtration barrier functions as a highly organized semipermeable membrane.
6. Glomerular filtrate has water, glucose, amino acids and creatinine.
7. Of which, glucose and amino acids are rapidly reabsorbed in the blood.
