Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body's cells. Every three to five seconds, nerve impulses stimulate the breathing process, or ventilation, which moves air through a series of passages into and out of the lungs.
Gas exchange is important as it is the transfer of oxygen from the surroundings to individual cells in the body, required by the cells for respiration.This process produces energy, essential for the organisms survival.hen oxygen goes into the alveoli, which then touches the â¦ capillaries carrying blood, the oxygen is diffused into the blood cells and the carbon dioxide is diffused into te alveoli as an apposite reaction. The carbon dioxide is then breathed out of the body back into the air.
