Alveoli are covered with capillaries. The deoxygenated blood that has come into the lung through the arteries flows through these capillaries, getting rid of carbon dioxide and accepting oxygen from the air that has been brought into the alveoli by the bronchioles. The carbon dioxide travels back out of the alveoli, through the bronchioles, into the bronchial tube system, and out the trachea each time you exhale.

The three kind of blood cells are:Red Blood Cells - ErythrocytesWhite Blood Cells - LeukocytesPlatelets - Thrombocytes
Mostly white blood cells.
Red Blood cells (RBCs).
There are two types of "blood cells." The red blood cells are generally very red unless the person has an abnormality. White blood cells and platelets are kind of an off-white. Blood plasma, the liquid the cells are housed in, is kind of a pale yellow
The air sacs in your body, known as alveoli, hold oxygen-rich air that is essential for respiration. When you inhale, oxygen from the air enters the alveoli and diffuses into the bloodstream, while carbon dioxide from the blood is expelled into the alveoli to be exhaled. This exchange of gases is crucial for providing oxygen to your body's cells and removing waste gases.
The two primary cells in blood are the red blood cells (erythrocytes) and the white blood cells (Leukocytes). Platelets (Thrombocytes) are a third kind of blood cell.

white blood cells
They are:- RBC (Red blood cells) WBC (White blood cells) Platelets There are only types, not 4 types of blood cells.
