Lung volumes and lung capacities refer to the volume of air in the lungs at different phases of the respiratory cycle. The average total lung capacity of an adult human male is about 3 litres of air. Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath. WebThe total lung capacity (TLC), about 6,000 mL, is the maximum amount of air that can fill the lungs (TLC = TV + IRV + ERV + RV). The vital capacity (VC), about 4,800 mL, is the total amount of air that can be expired after fully inhaling (VC = TV + IRV + ERV = …

WebLung volumes that are not affected by the rate of air movement in and out of the lungs are termed static lung volumes. The following five static lung volumes can be measured: VT (tidal volume), IRV (inspiratory reserve volume), ERV (expiratory reserve volume), IC (inspiratory capacity) and VC (vital capacity). Webair in, swirls around, picks up heat and evaporated water from nasal mucus, protects delicate respiratory surfaces from being effected.
