Web17 de jan. de 2024 · Gills are branching organs located on the side of fish heads that have many, many small blood vessels called capillaries. As the fish opens its mouth, water runs over the gills, and blood in the capillaries picks up oxygen that’s dissolved in the water. Then the blood moves through the fish’s body to deliver the oxygen, just like in humans. WebGills of Fish. Oxygen dissolves less readily in water.

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). WebFor example, mammals have a lung system, fish have gills with the countercurrent flow system, and single-celled organisms rely on the diffusion of gasses in and out of the cell.
