Answer:
The respiratory system is responsible for bringing the oxygen an organism will need to conduct cellular respiration. The respiratory system includes the lungs and other organs involved in breathing, such as:
- the trachea,
- bronchi,
- and alveoli.
When we inhale, oxygen from the air enters the lungs and diffuses into the bloodstream, where it is transported to the body's cells. Inside the cells, oxygen is used in the process of cellular respiration to produce energy in the form of ATP.
Hope that helps! Good luck! :)
