blood take oxygen from blood.
The blood passes through tiny capillaries that lie in close proximity to the alveoli in the lungs. This is where the gas exchange takes place.

Carbon dioxide leaves the blood and goes into the alveoli where it can then be breathed out of the body. It is also at this point that oxygen passes into the blood to be carried to where it is required for respiration - carbon dioxide being a by-product of respiration.
The correct order is:nosetracheamain bronchusbronchi (two) which is part of the lungsbronchioles - tinier than the bronchialveolismall capillaries surround each alveoli and cover each alveoli's surface-- CO2 passes from the alveoli to the venous blood supply; the blood passes O2 to alveoli and into the arterial blood supply
The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
alveoli in the lungs, where it passes through the thin walls of the capillaries surrounding the alveoli to enter the bloodstream. This process is driven by a concentration gradient, with oxygen moving from an area of high concentration in the alveoli to an area of lower concentration in the blood.

Alveoli are the small sacs within the lungs where gas exchange takes place. Oxygen from the air we breathe passes through the alveoli walls into the bloodstream, while carbon dioxide from the blood is removed and exhaled out of the body during respiration.
