How does an earthworm exchange gases in respiration?

environment. This gas exchange is vital to an earthworm's ability to live. Earthworms do not have specialized respiratory organs like we do; instead, they take in oxygen and expel carbon dioxide directly through their skin. read more

Earthworms exchange gases through their skin. The oxygen in air mixes with the slime on the earthworm’s skin and the oxygen and slime mixture passes through the skin and into the capillaries under the skin. Each segment, except for the 3 most anterior and one most posterior segments, have 2 tube structures called nephridia. read more
