What process will cause the oxygen to leave the blood?

Oxygen leaves the blood through the process of diffusion across the alveoli in the lungs into the bloodstream. This occurs due to differences in oxygen concentration between the air in the alveoli and the blood in the capillaries surrounding them.


What is the roll of the lungs in the circulation of blood in your body?

The lungs take in Oxygen which is carried by the blood to the cells of our body in order for respiration to occur and we get energy. The transfer of Oxygen to the blood happens in the Alveoli.

What happens to the oxygen when it reaches the alveoli?

When oxygen reaches the alveoli in the lungs, it diffuses from the air in the alveoli into the surrounding capillaries. The oxygen then binds to hemoglobin in red blood cells, which transports it to the body's tissues for use in cellular respiration.


What happens in the alveoli in the process of gas exchange.?

Alveoli- these are the small sac-like structures where gas exchange occurs with the blood. Its creates an ideal site for gas exchange between the air in the lungs and the blood in the capillaries.
