What is the difference between breathing and combustion
The process of breathing involves taking in oxygen-rich air and giving out carbon dioxide rich air.
The breathing involves two processes: Inhalation and exhalation.
During inhalation , the diaphragm moves down and the ribs move upwards and outwards, thereby increasing the space in the chest cavity. This leads to the movement of air inside the lungs.
During exhalation , the diaphragm moves to its former position and the ribs move downwards and inwards, thereby reducing the size of the chest cavity. This leads to the movement of air out of the lungs.
Combustion is a process of burning of a substance in the presence of the air or oxygen with liberation of heat and light.
