The respiratory system serves two main functions in the body. First, it allows oxygen to be transported from the air into the lungs with each inhale. Conversely, it removes carbon dioxide from the blood stream with each exhale. Secondly, with each breath, oxygen is absorbed by the lungs and then transported to the rest of the body by the blood. Oxygen is needed in each cell to keep the cell alive. Without oxygen, all our cells die and in turn, we die. The respiratory system is designed to ensure that all our cells have access to life sustaining oxygen

the respiraory system is an organ system which is used for gas exchange. Among four-legged animals, the respiratory system generally includes tubes, such as the bronchi, used to carry air to the lungs, where gas exchange takes place. A diaphragm pulls air in and pushes it out. Respiratory systems of various types are found in a wide variety of organisms. Even trees have respiratory systems.
