Respiratory System Quiz

The respiratory system is composed of various structures and organs that ensure that the body is able to maintain its internal environment through the exchange of air between the lungs and the atmosphere. In order to survive the body needs a constant supply of oxygen, which it obtains from the air.

The body also needs to dispose of carbon dioxide, made as a waste product from the process of cell metabolism. The ingestion of oxygen and the discarding of carbon dioxide occurs through the process of respiration or breathing.
