What is the respiration of a nematoda?

Answer 1

How breathe nematodes

Answer 2

Nematodes have a simple respiratory system that involves gas exchange occurring through their body surface by diffusion. They lack specialized respiratory organs like lungs or gills, relying instead on passive diffusion of oxygen and carbon dioxide through their thin, permeable cuticle. This allows nematodes to exchange gases with their environment effectively despite their small size and simple body structure.
