Question

Which of the following is the function of kidney in frog?

• A. Excretion
• B. Osmoregulation
• C. Haemopoiesis in larva
• D. All of the above

Answer 1

The correct option is D All of the above

Malphigian tubules are present as excretory organs in the kidney of frogs. These tubules help to filter the blood and in the excretion of the wastes. The wastes from the blood are discharged in the coelom and excreted out of the body. The nephrons in the kidneys are also responsible for the maintenance and regulation of water, ions, amino acids and other nutrients. The essential nutrients are reabsorbed and wastes are excreted. The spleen, liver and lymph nodes are the sites of haemopoiesis. In the tadpole larva, the haemopoiesis also occurs in the kidneys.

Thus, the correct answer is option D.
