Residual volume is the amount of air remaining in the lungs after a forceful exhalation, ensuring that the lungs do not collapse and continue to facilitate gas exchange. This volume is crucial for maintaining alveolar inflation and is typically measured to assess lung health and function.

Gas exchange is the biological process through which organisms exchange oxygen and carbon dioxide with their environment, crucial for cellular respiration and energy production. This process occurs primarily in the lungs of mammals, gills of fish, and across the cell membranes of single-celled organisms, enabling life-sustaining biochemical reactions.

Lung health is crucial for overall well-being, as it directly impacts the body's ability to oxygenate blood and remove carbon dioxide. Maintaining lung health involves avoiding pollutants, exercising regularly, and managing respiratory conditions effectively.

Lung function refers to the ability of the respiratory system to effectively exchange gases, primarily oxygen and carbon dioxide, between the air and the bloodstream. It is commonly assessed using spirometry, which measures parameters like forced vital capacity and forced expiratory volume, providing crucial information for diagnosing and managing respiratory conditions.
