Oxygen diffuses from the alveoli into the blood due to higher PO2 (partial pressure of oxygen) levels in the alveoli than in the blood.

What is the exchange of gases between the alveolar air and pulmonary capilaary blood?

The exchange of gases between the alveolar air and pulmonary capillary blood is called pulmonary gas exchange. Oxygen diffuses from the alveoli into the capillaries, while carbon dioxide diffuses from the capillaries into the alveoli. This process is essential for the body to obtain oxygen and release carbon dioxide.

How can the oxygen you bring into your body get to your circulatory system?

your lungs have structures called alveoli. The alveoli are surrounded by capillary beds which carry blood. The oxygen enters the alveoli when you inhale. The oxygen then diffuses from high concentration in your alveoli to low concentration the blood in the capillaries surrounding the alveoli.

What happens in pulmonary edema?

Normally very little to no fluid enters the alveoli of the lungs. In pulmonary edema there is increased pressure in the pulmonary veins. So fluid escapes in the alveoli of the lungs, making transfer of the oxygen impossible from such alveoli. Patient feels suffocated and starve for oxygen, in pulmonary edema.
