WebVentilation and Perfusion. Two important aspects of gas exchange in the lung are ventilation and perfusion. Ventilation is the movement of air into and out of the lungs, and perfusion is the flow of blood in the pulmonary capillaries.For gas exchange to be efficient, the volumes involved in ventilation and perfusion should be compatible. WebYour muscles need oxygenated blood to function. You would not have the muscle power to continue standing. Everything above your heart would completely fail, because it needs the pumping action of the heart to receive oxygenated blood. Your brain would quit, causing you to pass out, and die.
