Gas exchange is a biological process through which different gases are transferred in opposite directions across a specialized respiratory surface. Gases are constantly required by, and produced as a by-product of, cellular and metabolic reactions, so an efficient system for their exchange is extremely important. It is linked with respiration in animals, and both respiration and photosynthesis in plants.
The respiratory system â¦ does this through  breathing. When we breathe, we inhale oxygen and exhale carbon  dioxide. This exchange of gases is the respiratory system's means  of getting oxygen to the blood.To ensure that the body receives  enough oxygen and to expel waste, carbon dioxide.he respiratory system â¦ does this through  breathing.
