Web20 de fev. de 2024 · How is gas exchange carried out in flatworms? Platyhelminthes exchange gases exclusively by diffusion through their body surface. This is only possible because all cells are located relatively near their exterior, since gases diffuse cell by cell (the flat shape of these worms is a feature that allows this type of respiration). WebMost fishes exchange dissolved oxygen and carbon dioxide in water using gills which lie behind and to the side of the mouth cavity. The circulatory system consists of the heart, arteries, capillaries, and veins. The heart pumps the blood to the gills to be re-oxygenated.
