During its endless journeys to and from your heart, the four to five litres of blood in your body travels through three types of vessels – arteries, veins and capillaries. Arteries can be as thick as your thumb, and most carry oxygen-rich blood away from your heart. Veins carry oxygen-depleted blood back toward your heart. And tiny capillaries connect arteries and veins, forming a huge network, so they can reach every cell in your body. These fragile vessels are far narrower than a single strand of hair, so blood cells have to pass through them single file!
