During the process of external respiration, the exchange of respiratory gases, i.e., oxygen and carbon dioxide, takes place between the alveoli of the lungs and the blood in the pulmonary capillaries. Blood that is low in oxygen concentration and high in carbon dioxide concentration undergoes gas exchange with air in the lungs. We need to get oxygen from the air into the blood, and we need to remove waste carbon dioxide from the blood into the air. Respirationis the involuntary catabolic process which involves exchange of environmental oxygen and body's carbon dioxide. The ribs move outward because the central tendon of the diaphragm pushes down onto the liver and stomach , which act as fulcrum . I hope that helps. Hence, they have some special organs such as gills to absorb it. This was just the introduction of … Consequently, leaves, stems and roots of plants separately exchange gases. In physiology, respiration is the movement of oxygen from the outside environment to the cells within tissues, and the transport of carbon dioxide in the opposite direction. Gaseous Exchange is the process of swapping one gas for another. Pulmonary gas exchange takes place in the lungs between the alveoli and the blood.
