List the five part pathway of blood

________________ are small arteries that deliver blood to the capillaries from the larger arteries.

______________ connect arterioles and venules.

Capillaries permit exchange of ____________ and _____________ between the blood and tissues through their walls.

Groups of capillaries unite to form small veins called ______________.

Which is thicker- the tunica media or arteries or veins?

Arteries are very elastic, very contractile, are able to maintain their shape and do not readily collapse because of their thick ___________ _____________.

Veins are very thin with very little ____________ and _____________ tissue.

Because of the lack of support in veins, they can be easily ______________ and can be easily invaded by _____________.

Veins rely on ____________ ______________ contraction to help move blood back to the _____________.

Veins have _____________ which help aid the movement of blood and prevent backflow.

The veins which do not contain valves are the _________, __________ veins, and ______________ systems.
