The tiny blood vessels that surround the alveoli are
called alveolar capillaries
Capillaries cover the alveoli.

The exchange of carbon dioxide and oxygen occurs in the alveoli. Each alveolus is surrounded by a network of small blood vessels. Like the alveoli, these small blood vessels have extremely thin walls. Blood that enters the vessels has a high level of carbon dioxide, which it picked up from the body tissues. It contains little oxygen. The carbon dioxide leaves the blood and moves through the walls of the blood vessels and alveoli into the lungs. Oxygen from the air in the lungs then passes through the walls of the alveoli and blood vessels and into the blood. The blood, now rich in oxygen, leaves the lungs and travels to the heart. The heart then pumps it to cells throughout the body. The carbon dioxide is finally expelled from the lungs when we exhale.By ichigo kurosaki
There are many capillaries in the lungs. These small blood vessels are the site of gas exchange in the alveoli.
In the lungs. The blood is pumped from the right side of the heart to the lungs. Air moves into the trachea, the bronchi and finally to the alveoli. From the alveoli oxygen diffuses into the microcapilaries (small blood vessels) of the lungs.
They are called alveoli
Arteries usually carry O2 rich blood. Veins usually don't.
These are called the alveoli capillaries.
These tiny air sacs are called alveoli. These alveoli are surrounded by capilaries tiny blood vessells. These capilaries have holes that are to small for blood cells to escape but are big enogh for oxygen molecules to pass in to the blood stream and attach to the haemoglobin in your blood.
Histamine causes the dilation of the small blood vessels while constrict the large blood vessels.
Red blood cells are too small to contain blood vessels. They are cells and they travel in blood vessels.
Capillaries are the microscopic blood vessels that connect small arteries to small veins. Blood exchange takes place in capillaries.
Blood vessels are the tubes that carry blood. The smallest of the blood vessels are the capillaries.
small blood vessels called Vaso Vasorum these are for large arteries others by diffusion
