| Answer» Capillaries\xa0are very tiny blood vessels — so small that a single red blood cell can barely fit through them. They help to connect your arteries and veins in addition to facilitating the exchange of certain elements between your blood and tissues.\xa0Capillaries are the smallest of the body\'s blood vessels. They are only one cell thick, and they are the sites of the transfer of oxygen and other\xa0nutrients\xa0from the bloodstream to other tissues in the body.\xa0During early embryonic development new\xa0capillaries\xa0are\xa0formed\xa0through vasculogenesis, the process of blood vessel\xa0formation\xa0that occurs through a de novo production of endothelial cells which then\xa0form\xa0vascular tubes. | |
