Residual Volume - Respiration

No matter how hard one may try, the lungs are never empty of air; there is still 1650 cm³ of air left in it. This is known as residual volume. During inhalation, 350 (500-150) cm³ of fresh air enters and this mixes with the 1650 cm³ of air already in the lungs. The renewal of air is only one part in five. Therefore, the lungs have a constant composition of 15% oxygen and 5% carbon dioxide. This remains same even during exercise as increased ventilation during exercise supplies the extra oxygen requirements of the body.
