Which most accurately describes why air moves in and out of the lungs during respiration?
A. Dalton's Law: The partial pressures of oxygen and carbon dioxide determine the inspiration of oxygen and the expiration of carbon dioxide.
B. Boyle's Law: Pressure changes caused by changes in lung volume allow air to enter the lungs during inspiration and air to move out of the lungs during expiration.
C. Henry's Law: Increased lung volume during inspiration allows more air to enter the lungs while decreased lung volume during expiration allows more air to leave the lungs.
D. Murphy's Law: Increased lung volume increases pressure so air enters the lungs; decreased lung volume decreases pressure to air leaves the lungs.
