![]() This is the biochemical process in which oxygen diffuses out of the air and into the blood while carbon dioxide and other waste gases diffuse out of the blood and into the air. This is the physical process of conducting air to and from the lungs. Respiration by the respiratory system actually involves two subsidiary processes. Respiration by the respiratory system supplies the oxygen needed by cells for aerobic cellular respiration and removes the carbon dioxide produced by cells during cellular respiration. ![]() When cellular respiration is aerobic, it uses oxygen and releases carbon dioxide as a waste product. Cellular respiration is the metabolic process in which cells obtain energy, usually by “burning” glucose in the presence of oxygen. ![]() It is important to note that respiration by the respiratory system is not the same process as cellular respiration that occurs inside cells, although the two processes are closely connected. Respiration is carried out mainly by the respiratory system. Specifically, oxygen moves from the outside air into the body and water vapor, carbon dioxide, and other waste gases move from inside the body into the outside air. Respiration is the life-sustaining process in which gases are exchanged between the body and the outside atmosphere. ![]()
