WebGas exchange is the ‘swapping’ of gasses - absorbing oxygen into the blood and removing carbon dioxide from the blood. Diffusion moves oxygen out of the alveoli and into the blood. to-top WebTheir flat shape works to their advantage. With this shape all of their cells are close to the surrounding water for gas exchange and to eliminate nitrogenous waste (Cambell, 2008). These flatworms are bilaterally symmetrical, which means if you were curious enough to cut them down the middle either side will resemble the other.

Each segment generally has its own nerve and muscle tissues. Thus, localized muscle contractions can move just those segments needed for a particular motion. 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 means the water flows through the gills in one direction, allowing for more efficient gas exchange than if the water had to go in and out the same way.
