Capillaries are smaller, thinner and have less surface area than veins. Veins take blood to the heart, and capillaries are the thin tubes that connect the veins and arteries together.
They both carry blood in them, but veins take blood to the heart, artiries take blood from the heart, usually!
The capillaries are in between the red and blue veins :)
Veins, capillaries and arteries is that they are all stops for blood.
Capillaries are bridges between the arterys and veins
Capillaries.
plmonary veins begin as capillaries and end as capillaries
arteries take blood away from heart. veins take blood to the heart. capillaries have thin walls
Arteries carry oxygenated blood away from the heart, to the cells that need them. Veins carry blood containing carbon dioxide back to the heart after the oxygen has been given to the cells. Capillaries are the thinnest arteries and veins. They are only one cell wide. As the blood cell passes through the very thin capillary, the cells on either side are given oxygen and carbon dioxide is taken from them. Therefore, the capillaries connect the arteries and veins. Veins are thinner than arteries. Arteries are thicker than capillaries.
the three blood vessels are the Veins capillaries Arteries the arteries.
Capillaries connect the smallest branches of arteries and veins The walls of capillaries are just one cell thick. Capillaries therefore allow the exchange of molecules between the blood and the body's cells - molecules can diffuse across their walls. This exchange of molecules is not possible across the walls of other types of blood vessel.
Capillaries are the structures that connect arteries to veins.
