What three tissues are the blood vessels made from?

Arteries

These carry blood away from the heart, have thicker and stronger walls, have the highest BP

Veins

These carry blood to the heart, have lower BP and possess periodic valves to prevent back flow.

Capillaries

These are one layer thick epithelium, have diffusion and exchange potential, are the functional unit of the system.

The Endocardium, the inner most layer of the heart, made up of what type of tissue?

Endocardium, Myocardium, epicardium, pericardium

What are the four tissue layers of the heart (from the innermost to the outermost)?

Endocardium

This layer of the heart is the inner covering, continuous with lining of blood vessels.

Myocardium

This layer of the heart is the heart's muscle, cardiac muscle, and is highly vascular

Epicardium
