Question

Gas transfer systems in complex animals rely on the two processes of diffusion and bulk flow to move O2 from the environment into the mitochondria of cells. Define and contrast these two transport mechanisms and describe at which points in the process of gas transfer (from the environment to the mitochondria) they are utilized in a vertebrate. Be sure to include a description of the forces behind each of these two mechanisms.

Answer 1

the According to the given question Gas Transfer Systems in complexe ansinals Rely nolially takes and Spreading takes Spot at the Intersection of alvéola & the blood Uube that has an internal diameter of hainlike themnes which is also called as blood capillaries. When the overtow take place through blood. So, the blood now which destinates the cells, Spread the O₂ into the Cell for the mitochondria, while the co, is spreading out from the cell into the blood Stream. The Erlensing in the Spreading is the aim the gradient & the Components to move trond the neet lovel Congrentration to the below concentration.
