Question

What happens to glucose which enters the nephron along with filterate during excretion in human beings? State two vital functions of kidney.

Answer 1

The molecules of glucose are very small. Hence, when it enters the nephron along with the filtrate during excretion, it is passed into the nephron tubule along with urea. However, by tubular reabsorption, the glucose along with some water and other important ions are reabsorbed and are used by the body.

Vital functions of kidneys include:

1. They remove the waste products like urea and other salts from the body.

2. They help in maintaining homeostasis of the body by regulating the concentration and volume of body fluids like water.
