The capillary is the only blood vessel where things can be exchanged because it is so thin (one cell thick). Capillaries have a single cell layer of squamous epithilium.
Nutrients and oxygen are exchanged for carbon dioxide and wastes at tiny blood vessels called the capillaries. These are found with many other capillaries in a capillary bed.
Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
Oxygen, carbon dioxide, and water are the substances exchanged between the alveoli (air sacs) and the capillaries in the lungs.
There are many substances they exchange, but the main ones are oxygen from the blood to the cells and CO2 from the cells to the blood.

I believe the tiny blood vessels are called capillaries, located in the lungs.
Tiny blood vessels that allow substances to pass between the blood and body tissues are called
The three types of blood vessels are:1. Arteries2. Veins3. Capillaries (small blood vessels in the tissues)They are:(1) Arteries - These are the blood vessels that carry blood away from the heart. They generally carry oxygenated blood except the pulmonary artery.(2) Veins - These are the blood vessels that carry blood towards the heart. They generally carry de oxygenated blood except the pulmonary vein.(3) Capillaries - They generally form a capillary network through which substances are exchanged between the blood and tissues. Capillaries carry blood from arterioles (branches of artery) to venoules (branches of vein).
