The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. In air-breathing vertebrates like human beings, respiration takes place in the respiratory organs called lungs.
These are cells that contain a nucleus (brain of the cell) and organelles (little organs that each have their own job inside the cell). The process of aerobic cellular respiration takes place mostly inside of the mitochondria, an organelle that is known as the powerhouse of the cell.
