Oxygen and carbon dioxide are exchanged across the capillary walls in the process known as gas exchange or respiration. This occurs in the lungs during pulmonary respiration and in the tissues during systemic respiration. Capillaries are tiny blood vessels with thin walls, allowing for the easy diffusion of gases between the bloodstream and surrounding tissues. Oxygen is transported from the lungs to the cells through arteries, and carbon dioxide is carried from cells to the lungs through veins. The exchange of gases occurs due to differences in partial pressures between the blood and tissues, with oxygen diffusing into the cells and carbon dioxide diffusing out of the cells into the bloodstream. This crucial exchange ensures that oxygen is delivered to the tissues and carbon dioxide, a waste product of cellular respiration, is removed from the body.
