Describe the process of respiration

The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

Respiration is a biochemical process in which cells of an organism obtain energy by combing oxygen and glucose,resulting in the release of carbon dioxdide,water and ATP(the currency of energy in cell).
