The human respiratory system is responsible for taking in oxygen and getting rid of carbon dioxide. It does this through key organs like the lungs, trachea, and diaphragm, which work together to allow us to breathe. When we inhale, oxygen travels from the air into our lungs, where it is then transferred to the blood, and when we exhale, we release carbon dioxide back into the air.
