Capillaries are the smallest blood vessels in the body and they connect arterioles (small arteries) to venules (small veins). Capillaries are the site of gas and nutrient/waste exchange between the blood and the surrounding tissues.
The smallest vessels in the human body are capillaries. They are the blood vessels that absorb oxygen into the blood and returning blood cells that lack oxygen back into the heart and lungs to be oxidised.
Capillaries are very thin blood vessels. Oxygen and nutrients and hormones can pass through the walls of the capillaries and reach the body's cells, while red blood cells remain in the capillaries.
The circulatory system is an example of an organ system in the human body. The circulatory system is made up of the heart, arteries, veins, and capillaries.

cappillaries==============The smallest veins in the body are the venules. Capillaries join venules and arterioles (the smallest arteries) together. Arteries carry the blood from the heart around the whole body; while veins carry the blood back to the heart. They are joined by the capillaries, where the most important actions happen.More information in related links.

Blood is stored in the human body primarily in the circulatory system, which includes the heart, arteries, veins, and capillaries.
