  1. Dead space

    In physiology, dead space is the volume of air which is inhaled that does not take part in the gas exchange, either because it remains in the conducting airways, or reaches alveoli that are not perfused or poorly perfused. In other words, not all the air in each breath is available for the exchange of oxygen and carbon dioxide. Benefits do accrue to a seemingly wasteful design for ventilation that includes dead space. Fish waste none of their ventilation because they exchange gases from a continuous unidirectional stream of water that crosses their gills. Mammals breathe in and out of their lungs, wasting that part of the inspiration which remains in the conducting airways where no gas exchange can occur. ⁕Carbon dioxide is retained, making a bicarbonate-buffered blood and interstitium possible. ⁕Inspired air is brought to body temperature, increasing the affinity of hemoglobin for oxygen, improving O2 uptake. ⁕Particulate matter is trapped on the mucus that lines the conducting airways, allowing its removal by mucociliary transport. ⁕Inspired air is humidified, improving the quality of airway mucus. About a third of every resting breath has no change in O2 and CO2 levels. In adults, it is usually in the range of 150 mL.
