The alveolis.
The tiny air sacs are called alveoli. Oxygen from the air enters the bloodstream through the walls of the alveoli, while carbon dioxide from the bloodstream is released into the air sacs to be exhaled.
The tiny air sacs in the lungs, known as alveoli, are surrounded by a network of capillaries. These capillaries are tiny blood vessels that facilitate the exchange of oxygen and carbon dioxide between the air in the alveoli and the blood. The close proximity of the alveoli to the capillaries allows for efficient gas exchange, essential for respiration. Additionally, the alveolar walls are composed of a thin layer of epithelial cells, which further aids in this exchange process.
