When the heart pumps oxygen-poor blood to the alveoli, carbon dioxide leaves the blood. This gas exchange occurs in the alveoli of the lungs, where carbon dioxide diffuses from the blood into the alveoli and is then exhaled. Simultaneously, oxygen from the inhaled air enters the blood, allowing for the replenishment of oxygen levels. This process is essential for maintaining proper respiratory function and overall cellular metabolism.

Oxygen enters the blood in the alveoli of the lungs
Alveoli.
Oxygen is removed from the alveoli by the cappillaries.
Oxygen enters the blood through the alveoli in the lungs during inhalation, where it diffuses into the bloodstream. Carbon dioxide leaves the blood in the same location, diffusing from the blood into the alveoli to be exhaled during exhalation.
Oxygen enters the blood in the alveoli of the lungs
Alveoli (plural) and alveolus (singular)
This is the alveoli, which are tiny air sacs in the lungs where gas exchange occurs. Oxygen diffuses from the air into the blood, while carbon dioxide diffuses from the blood into the air in the alveoli.
They are called alveoli
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.
Oxygen enters the blood through the thin walls of the alveoli in the lungs during the process of respiration. This occurs through a process called diffusion, where oxygen moves from an area of high concentration in the alveoli to an area of lower concentration in the blood vessels surrounding the alveoli.
