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.
This process is thru the use of passive transport. The oxygen in you lungs are of a higher concentration than it is in your blood and since hemoglobin likes oxygen it moves na â¦ turally into the the blood supply in the lungs. Your blood is then returned to the heart and pumped throughout the body.Because your blood has more oxygen in it than your cells do the blood thru the use of passive transport again give the oxygen to the cells and pick up waste product and carbon dioxide to be returned eventually to the heart.apillaries around these air sacs allow blood to exchange oxygen for unwanted carbon dioxide. The oxyge â¦ n-rich blood then returns to the heart to be pumped to the rest of the body. The carbon dioxide in the lungs is passed out of the body through the mouth and nose when we exhale.
