Question

Why do most multicellular organisms require more than just diffusion to facilitate gas exchange? What is the other process called? Name all the places in our body where these two different processes occur (i.e. where do we get diffusion and where do we get the other process).

Answer 1

The description including its problem is described throughout the segment below on explanation.

Step-by-step explanation:

Surface layer influences combustion efficiency, the larger the surface region, the more and more fuel traded. Hence, gills as well as lungs become established in the organism's purpose of providing an enormous surface area for both the necessary currency value of gas towards the outer atmosphere.

• The ranges among gas exchanger as well as shallow tissues become ideal through dissemination to fulfill the necessity so a range of respiratory substances is required. Respiratory interfaces are coated with epithelial cells to allow exchanging of gases.
• The oxygen through both the respiratory system would be transferred into the bloodstream, as well as the RBC collect the CO2 from the cells it to the lungs for oxygenation. Exterior ventilation, oxygen absorption from capillaries to CO2 absorption from capillary to alveoli. Inner ventilation happens at the surface including its body cells.
