lung capacity

Lung capacity refers to the maximum amount of air the lungs can hold during different breathing phases. It includes several measurements, such as tidal volume (air during regular breaths), inspiratory reserve volume (extra air you can inhale after normal inhalation), and vital capacity (total air exhaled after deep inhalation). These numbers help assess respiratory health and how efficiently your lungs function. Factors like age, fitness, and lung health influence lung capacity. Understanding it is useful for diagnosing and managing breathing conditions or tracking physical fitness progress.
