The moist skin of earthworms is used for gas exchange. Furthermore, their closed circulatory systems contain blood vessels close to the skin which allow for the exchange of O2/CO2.

The epidermal layer has blood capillaries, which have looped out from the vascular system circulating the blood. These blood capillaries are so close to the skin that the gases can diffuse from the surroundings into and out of the blood through the skin and the capillary walls. The blood contains haemoglobin in solution which circulates the gases through the body.
