WebThe fish opens its mouth to let water in, then closes its mouth and forces the water through the gills and out through the operculum (gill cover). This allows for more efficient gas exchange than if the water had to go in and out the same way. This is important for fish becaus of the low oxygen concentration in water. Summary.

No, fish do not have lungs like land-dwelling mammals. Instead, they use their gills to get oxygen from the water or air. Fish are able to extract oxygen from the water through diffusion, which is a process in which oxygen molecules move from an area of higher concentration to an area of lower concentration. flannel with jean shorts

"WebA fish had gills, made up of gill filaments containing lamellae, which provide a very large surface area for oxygen to diffuse out of the water as it moves over them. The blood vessels are in very close proximity to the lamellae, allowing a short diffusion pathway.A fish also utilises a countercurrent system, where the blood flows in the opposite direction to the … " - How are gills adapted for diffusion

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. Web3 de dez. de 2024 · Diffusion In Fish Gills. It’s all about partial pressure. In a fish, oxygen moves from the surrounding water through the gills to the blood and finally the tissues. At each step, the oxygen level becomes lower — otherwise the oxygen wouldn’t diffuse.
