narrowest blood vessel in vertebrates measuring 0.008-0.02 mm in diameter, barely wider than a red blood cell. Capillaries are distributed as beds, complex networks connecting arteries and veins. The function of capillaries is to exchange materials with their surroundings. For this reason, capillary walls are extremely thin, consisting of a single layer of cells through which nutrients, dissolved gases, and waste products can easily pass. This makes the capillaries the main area of exchange between the fluid (lymph) bathing body tissues and the blood. They provide a large surface area in order to maximize diffusion.
All body cells lie close to capillaries so they can receive the food and oxygen they require from the capillaries. Networks of capillaries are especially extensive in certain parts of the body. For example, in the lungs they surround the air sacs (alveoli), taking up oxygen and releasing carbon dioxide. They are also found in the lining of the gut - in little finger-like projections called villi - where they absorb the products of the digestion of food.
to supply tissues with components of, and carried by, the blood, and also to remove waste from the surrounding cells

The function of the capillaries in the circulatory system is to allow diffusion of wastes, oxygen, and nutrients to the tissues. The rest of the circulatory system is designed to move the blood to the capillaries so they can perform this function.

The blood vessels, which include the capillaries, function to distribute nutrients such as glucose and oxygen to the body tissues and to carry wastes such as carbon dioxide and urea away from the tissues to be excreted.
The function of blood capillaries is to provide cellular, or tissue, respiration, provide nutrients and remove waste products. They are the tiny blood vessels that are between the venules and arterioles and the interstitial space between cells.
Capillaries are part of the cardiovascular system. The capillaries are the smallest type of vessels of the system. They reside in almost all of the tissues in the body. The capillaries are so small, that they can only allow for one red blood cell to pass through it. The capillaries is where the gas exchange from blood to tissue and tissue to blood take place.
