(cellular) respiration
The gas we take in when we inhale is oxygen.
air, which is a mix of several gasses
The percentage of oxygen in inhaled air by humans is approximately 21%. This oxygen is then absorbed by the lungs and transported by the blood to the cells where it is used for energy production in the body.
Inhaled oxygen diffuses through the walls of the alveoli in the lungs, then into the bloodstream where it binds to hemoglobin in red blood cells for transportation to tissues and cells in the body.
Oxygen from the air is inhaled into the lungs, where it diffuses into the bloodstream. The heart then pumps this oxygen-rich blood to all the important organs through a network of blood vessels. The organs extract the oxygen they need for cellular function from the blood.

Oxygen is required so that we can make ATP. ATP is the energy that the cell needs to function.
The gas that the body must be supplied with to function is oxygen. Oxygen is required for cellular respiration in the body, where it is used to generate energy from nutrients.
