What helps in the earthworm in exchange of gases?

In earthworm, the exchange of gases occurs through the moist skin. In fishes it takes place through gills and in insects through the tracheae. In a plant the roots take in air present in the soil. Leaves have tiny pores called stomata through which they exchange gases.

How do earthworms take in and give out air?

Earthworms do not have lungs; instead, they breathe through their skin. Their skin needs to stay moist to allow the passage of dissolved oxygen into their bloodstream. Earthworm skin is coated with mucus, and they need to live in a humid, moist environment.

Where does gaseous exchange occur in earthworms?

Earthworms have a series of thin-walled blood vessels known as capillaries. Gas exchange occurs at capillaries located throughout the body as well as those in the respiratory surface.

How do worms exchange oxygen with their environment?

Instead of exchanging gases directly with their environment, earthworms have a network of capillaries just under the skin through which gas exchange takes place. A blood-like fluid circulates throughout the body, transporting oxygen to cells and carrying away carbon dioxide.

How does gaseous exchange takes place in earthworm and fish?

Gaseous exchange occurs through its skin. The thin, moist skin is supplied with a network of capillaries which absorb oxygen from the atmosphere and deliver it to the rest of the body. The absorbing surface or the network of capillaries also gets rid of carbon dioxide from the body.

Which body structure do earthworms use for gas exchange?

Earthworms and amphibians use their skin (integument) as a respiratory organ. A dense network of capillaries lies just below the skin and facilitates gas exchange between the external environment and the circulatory system.

What is respiratory organ of earthworm?

Earthworms do not have lungs. They breathe through their skin. Oxygen and carbon dioxide pass through the earthworm’s skin by diffusion.

How do earthworms and frogs breathe?

Answer : We humans respire through lungs, fishes through gills, the same way earthworm and frog respire through their skin. The skin of such animals is thin, moist and slimy which help in easy gaseous exchange show the skin, thus, facilitating respiration.
