What are Arterioles?

Considered resistance vessels; assist with regulating blood flow through contraction and relaxation

36

What are Capillaries?

Nutrients and waste products are exchanged between the tissue and blood

37

What are venules?

Collect blood from capillaries

38

What are the three layers that line arterial walls?
