Oxygen diffuses from the alveoli into the blood due to higher PO2 (partial pressure of oxygen) levels in the alveoli than in the blood.
Oxygen is transferred from the lungs to the red blood cells which then transport them to the whole of your body including the capillaries.
because co2 is unuseful
In the alveoli
In the alveoli
By diffusion across q capillary wall
Oxygen enters the blood in the alveoli of the lungs
Oxygen enters the pulmonary blood in the capillaries of the alveoli -- the air sacs of the lungs.
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.

alveoli
The capillary net rould the alveoli.
In the lungs are small air sacs called alveoli. These alveoli are covered with blood capillaries. Oxygen and Carbon Dioxide diffuse through the alveolar capillary membrane. Oxygen diffuses from the alveoli to the blood capillary and carbon dioxide diffuses from the capillary to the alveoli and you breath it out of your body.
The air flow of the lungs is as follows... From the Nasal cavities to the Pharynx to the Larynx to the Trachea to the Bonchi to the Bronchioles Alveoli ...The respiratory gases, oxygen, and carbon dioxide, diffuse across the Aveolar pulmonary Capillary membrane. Hope this diaphragm answers your question
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.
