Diff between blood vessels and cappillaries |
| Answer» Capillaries are a class of blood vessels (the smallest ones). Blood vessels are classified, for the most part, as arteries, capillaries, and veins, in that order according to the direction of blood flow. Capillaries are the microscopic blood vessels that connect the smallest arteries to the smallest veins. Capillaries are the site of most exchanges of material between the blood and surrounding tissues. | |
