What is gaseous exchange?
Gaseous exchange is the process whereby gaseous substances especially oxygen and carbon dioxide move from one point to another in living systems.
Oxygen from the atmosphere goes into the body via the nose and is passed on to the lungs. The gases are exchanged in a compartment called alveoli or air sac.
The air sac then passes the oxygen to the red blood cells, which circulate it round the body to organs.
