2. Explain the functions of the respiratory system
Delivers air to the gaseous exchange in the lungs surfaces, allows oxygen to diffuse into the blood so it can be transported to cells, to allow carbon dioxide to diffuse from blood to air to be exhaled
To allow carbon dioxide to diffuse from air to blood to be exhaled, to allow oxygen to diffuse into the blood to transport to tissues, delivers gaseous exchange
Delivers gaseous exchange to the lungs surfaces and allows oxygen to be diffused into the skin to allow it to be transported to cells
