The movement of gases between the lungs and the body tissues mainly depends on gaseous diffusion. This is the process by which gases move from an area of higher concentration to an area of lower concentration until equilibrium is reached. This process occurs across the respiratory membrane in the lungs and the capillary walls in the body tissues. Active transport is not involved in the movement of gases, and membrane dialysis and membrane transport are not relevant to this process.
