The capillaries are the primary sites of exchange between blood and tissues. Capillaries are small blood vessels with thin walls that allow for the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues. These exchanges are essential for maintaining the proper function of tissues in the body.

To allow Oxygen to travel to every Cell in a living organism there is a gas exchange between nearby Capillaries and the cells of that organism.The same exchange works the other direction to take away waste products of cell living
Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.

To exchange oxygen and nutrients between arterioles and venules

capillaries
The site of gas exchange in the tissues is the capillaries. Here, oxygen from the red blood cells is released into the tissues, while carbon dioxide from the tissues enters the blood to be carried away. This exchange occurs due to differences in partial pressures of gases between the blood and the tissues.
gas exchange occurs between the thin walls of the alveoli and the thin walls of the capillaries
