If a worm is dried up by the sun, it will die because the exchange of gases can’t take place. During this process, carbon dioxide is produced. This lets it absorb the oxygen it needs and expel carbon dioxide. The worm’s skin is protected by a thin cuticle and kept moist by a slimy mucus. When a frog breathes through his skin, it's called cutaneous gas exchange. In earthworm skin is the only organ of respiration. In the cells, oxygen is used up for oxidation of food. The oxygen gas absorbed by the skin diffuses into the blood and transported to all the cells of the body. So, in earthworms respiration process takes place through its moist, thin and highly vascular skin.

Cutaneous respiration in earthworm., Biology The respiration performed by the skin is called cutaneous respiration. This means he's exchanging oxygen for carbon dioxide, similar to the way your lungs exchange the gases. Then the heart pumps out the oxygenated blood to the head are of the earthworm. Every time that the earthworm moves, the … The gases … The mucous in the earthworms skin helps the earthworm take the oxygen into the body and goes to the circulatory system were the oxygen goes to the heart. Respiration in Cockroach takes place through their spiracles and in Earthworm, oxygen is absorbed passively through their moist skin.
