Question

How does the skin of earthworm help in respiration?

Priyanka Sahu · Accepted Answer

Dear Student,
Earthworms have no respiratory organ and hence the exchange of
gases (respiration) takes place through the moist skin The oxygen
from the environment diffuses passively across the moist skin and
it is carried by the circulatory system to the cells Similarly
carbon dioxide from the cells is also carried by circulatory system
and diffused out through the moist skin
So they respire through their moist skin and will
die if their skin dries out
