How are fish gills adapted for diffusion

Web17 de jan. de 2024 · But instead of lungs, they use gills. 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.

WebAdaptations of the Alveoli. The lungs are the gas exchange surface in humans and so are adapted to maximise the exchange of gas by diffusion. Inside the lungs there are many rounded alveolar sacs which give a very large surface area to volume ratio. These alveoli are highly specialised structures. They (and the capillaries around them) have ... WebBony fish use countercurrent flow to maximize the intake of oxygen that can diffuse through the gill. Countercurrent flow occurs when deoxygenated blood moves through the gill in one direction while oxygenated water moves through the gill in the opposite direction.
