Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. Cellular respiration is considered an exothermic redox reaction which releases heat. The overall reaction occurs in a series of biochemical steps, most of which are redox reactions themselves.
Do you know what happens when you breathe? Each respiration, or breath, allows the body to take in oxygen and expel carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen to the blood. Respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. Oxygen enters the respiratory system through the mouth and the nose every time you breathe in. The oxygen then passes through the larynx (also known as your âvoice boxâ) and then through the trachea to the chest cavity.
