SpletAlveolar ventilation in the upright position gradually falls from the base to the apex of the lung because of posture and gravity. The lung is a visceral elastic organ and because of the lung’s weight, it tends to assume a bell shape in the chest cavity. Splet24. mar. 2024 · Your lungs are the pair of spongy, pinkish-gray organs in your chest. When you inhale (breathe in), air enters your lungs, and oxygen from that air moves to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathed out). This process, called gas exchange, is essential to life.

SpletIf the problem is internal and there would be an obstruction that is considered as a mechanical ventilation problem due to impaired oxygen exchange. Pulmonary emboli or a clot in the lungs is a typical example of blocking oxygen exchange. Pulmonary edema, which is increased lung fluid or edematous lungs, also poses a threat in oxygen exchange. SpletThe lungs (balloons) inflate as air enters until the pressures inside and outside are equal.
