The affinity of the oxygen and hemoglobin or improving of the oxygen uptake in the inspired air through the body temperature. Interstitium possible and bicarbonate buffered of the blood are made by the carbon dioxide retained in the lungs.
There is no exchange of the oxygen or carbon dioxide gases in the lungs known as the dead space. The conducting of the airwaves or reaches of alveoli that are poorly perfused in the human body is known as the dead space of the volume of the air in the inhaled gases that does not part in the gas exchanges in the lungs.
The dead space is high in the old man body because of the low supply of the blood to the lungs. Apparatus dead space, alveolar dead space, physiological dead space, and anatomical dead space are the different types of the dead space present in the old human body. Hint: The gas does not exchange in the lungs because of the dead space volume occupied by the gas.
