A capillary is an extremely fine blood vessel that is soft and elastic. Large in number, capillaries tie the bloodstream together by forming complex capillary networks. In capillaries, blood pressure is very low. Capillaries are constantly evolving and play a part in nourishing the body's tissues. Capillaries are connected to veins and arteries, and transport nutrients, including glucose and oxygen. They are highly present in muscles, the liver, lungs, kidneys and the nervous system.
