Hello! Welcome to the O2 Factory where diffusion occurs and allows you to breathe.
Deoxygenated blood cells travelling through the respiratory system to the alveoli
Alveolus where deoxygenated haemoglobin cells are turned on to oxyhemoglobin via a process called diffusion.
This is the process of diffusion where deoxygenated blood passes through a capillary (a type of blood vessel) and basically swaps the CO2 in the deoxygenated blood with the oxygen in the alveolus to make oxyheamaglobin
