Final answer:
Respiration is the process in which gases are exchanged between the body and the outside air. It involves two subsidiary processes: ventilation (breathing) and gas exchange. The respiratory system, which includes the lungs, is responsible for facilitating respiration and supplying oxygen to the cells for cellular respiration.
Step-by-step explanation:
Respiration is the process in which gases are exchanged between the body and the outside air. It involves two subsidiary processes: ventilation (breathing) and gas exchange (the biochemical process in which oxygen diffuses into the blood and carbon dioxide diffuses out of the blood). The respiratory system, which includes the lungs, is responsible for facilitating respiration and supplying oxygen to the cells for cellular respiration.
The correct answer is metabolism. Metabolism is the set of chemical reactions that occur in living organisms to maintain life. It involves the breakdown of nutrients to obtain energy and the synthesis of molecules needed for various cellular processes. It involves two subsidiary processes: ventilation (breathing) and gas exchange (the biochemical process in which oxygen diffuses into the blood and carbon dioxide diffuses out of the blood). Respiration, ventilation, and oxygenation are specific components or processes related to the overall metabolic activities of cells.
