Veins
What are the three types of arteries?
Elastic arteries
Muscular arteries
Arterioles
What are the three types of capillaries?

Sinusoidal
What do all arteries do?
They carry blood from the heart
What do all veins do?
They transport blood to the heart
What are capillaries and what do they do?
2
Tiny blood vessels which pass between the cells of the different tissues and organs
They form networks called capillary beds
What are the three layers of blood vessel walls?
Tunica interna (intima)
Tunica media
Tunica externa (adventitia)
What is the tunica interna?
Endothelium
What is the tunica interna made of?
A single layer of simple squamous epithelium with a small amount of areolar connective tissue underneath
