capillaries, since they are only one cell wide.
arteriols
Venules, they are smaller and thinner than veins.
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.
No its not
No, arteries carry blood away from the heart, veins carry blood back to the heart, and capillaries are where blood disperses throughout areas in the body. capillaries are sort of in between, but not really.
capillaries are smaller than arteries and veins. they need to be small or it would look wierd with big buldges sticking out of your eye lids. :P
plmonary veins begin as capillaries and end as capillaries
All arteries, as they move towards the body become smaller and smalled leading to capillaries. Capillaries then, rejoin to create veins.
Arteries and veins can be different sizes, because large arteries branch into smaller arteries, which branch into capillaries. These capillaries branch into small veins, which branch into large veins. So yes, they can be (and usually are) the same size if (I am surmising this) they are the same distance from the capillaries.
the three blood vessels are the Veins capillaries Arteries the arteries.
Capillaries are the structures that connect arteries to veins.
Arteries divide into smaller vessels called Arteriols. Arteriols subdivide into even smaller vessels called capillaries, where oxygen, nutrients, hormones are delivered to the tissues of the body. Waste products are also picked up by capillaries and delivered to venules which grow into larger vessels called veins. Veins deliver deoxygenated blood back to the heart.
