The primary function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli. The layers of cells lining the alveoli and the surrounding capillaries are each only one cell thick and are in very close contact with each other. This barrier between air and blood. barrier. Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.
Gas Exchange Between Alveoli and Capillaries
Three processes are essential for the transfer of oxygen from the outside air to the blood flowing through the lungs: ventilation, diffusion, and perfusion.
Ventilation is the process by which air moves in and out of the lungs.
Diffusion is the spontaneous movement of gases, without the use of any energy or effort by the body, between the gas in the alveoli and the blood in the capillaries in the lungs.
Perfusion is the process by which the cardiovascular system pumps blood throughout the lungs.
The body's circulation is an essential link between the atmosphere, which contains oxygen, and the cells of the body, which consume oxygen. For example, the delivery of oxygen to the muscle cells throughout the body depends not only on the lungs but also on the ability of the blood to carry oxygen and on the ability of the circulation to transport blood to muscle.

the oxygen present in nature is taken by animals for respiration and animals release carbon dioxide as a product of respiration the carbon dioxide in the atmosphere is taken as the organic compounds of the plants which is later converted into fossil fuels like coal and petroleum the CU to present in the atmosphere is also formed into carbonates in water and later forms limestone. the plants also release oxygen in nature as a product of photosynthesis.
