Gas exchange in the body of the person happens 2 of lung tissue and
.Lung - > what the gas exchange between the lung and in alveolar capillaries. The oxygen from lungs to spread into the alveolar capillaries around the lung alveoli and combines with hemoglobin (haemoglobin;Hb) surface of red blood cells become oxy hemoglobin gold bill (oxyhemoglobin; HbO2), which are red blood oxy ฮีโมโก ลบิน will be sent into the heart and pumped to various tissues throughout the body
.Tissue - > oxyhaemoglobin will decay to oxygen and hemoglobin. Oxygen diffusion into the cell to cell of tissue oxygen
.While the tissue receiving oxygen. Carbon dioxide produced in the cell, it will spread into the blood. Carbon dioxide mainly reacted with water in the red blood cells is the carbonic acid (H2CO3).(HCO3 -) and hydrogen ion (H) when blood with hydrogen carbonate ion flow into the heart will be much smoke injection on lung alveolar capillaries aroundAs a result, the density of carbon dioxide in the capillaries than carbon dioxide in the air sacs, the lungs. The diffusion of carbon dioxide from the air capillaries into the lungs.
