Question

1. Explain tubular reabsorption
and tubular secretion.

2. Explain the functions
performed by Kidney. ​

Answer 1

1. Ans= Tubular secretion is the transfer of materials from peritubular capillaries to the renal tubular lumen; it is the opposite process of reabsorption. This secretion is caused mainly by active transport and passive diffusion. Urine is the substance leftover in the collecting duct following reabsorption and secretion
2. Ans= Most people know that a major function of the kidneys is to remove waste products and excess fluid from the body. These waste products and excess fluid are removed through the urine. The production of urine involves highly complex steps of excretion and re-absorption.

Answer 2
