Diffusion is a process in which material travels from regions of high concentration to low concentration until equilibrium is reached. In this case, blood with a low concentration of oxygen molecules circulates through the gills. cindy braddock 25 and jake day

"WebGas exchange is important for fish as they need oxygen for respiration. Considering Fick’s law, in order to maximise the rate of gas exchange, fish have many gill filaments covered in lamellae, maximising the surface area available.In order to maximise the concentration gradient, the gills have a good blood supply to ensure that oxygenated ...

WebAbstract: Over the past 20 years, a variety of models have been developed to simulate the bioconcentration of hydrophobic organic chemicals by fish. These models differ not only in the processes they address but also in the way a given process is described. Processes described by these models include chemical diffusion through the gill's interlamellar … WebThis massively increases the fish’s ability to absorb oxygen from the water as a diffusion gradient is always maintained.
