The respiratory system's main function is to supply the body with oxygen and remove carbon dioxide. It includes organs like the lungs, which facilitate the exchange of these gases. When we inhale, oxygen from the air is taken into the lungs and transferred to the bloodstream. When we exhale, carbon dioxide, a waste product, is expelled from the body.
