👉 Sideration is a process in which oxygen and carbon dioxide are exchanged between living organisms through their cells. This exchange occurs through chemical reactions that occur within the cell, and it can be thought of as a biological "exchange" or "transport." In other words, when oxygen from the atmosphere enters a cell, it binds to hemoglobin molecules on the surface of red blood cells, which then transport carbon dioxide out of the cell. This process is crucial for the survival of living organisms, as it
