Compliance is the measure of lung and chest wall distensibility (stretchiness) and is defined as volume change per unit of pressure change. Airway resistance is determined by the length, radius and cross-sectional area of the airways and density, viscosity and velocity of the gas (Poiseuille's law). Ventilation is the mechanical movement of gas or air into and out of the lungs. Tidal volume :The amount of gas inspired or exhaled each breath Partial pressure is directly proportional to the percentage of that gas in the mixture of gases The structure and function of the pulmonary system.
