Artery
Muscular blood vessels that carry blood away from the heart
Atherosclerosis
The buildup of plaque inside arteries
Blood

Heart Attack
Occurs when the blood supply to part of the heart muscle is blocked and cardiac muscle fibers die.
Hypertension
High blood pressure
Plasma

Platelet
Are cell fragments involved in blood clotting. They stick to tears in blood vessels and to each other, forming a plug at the site of injury. They also release chemicals that are needed for clotting to occur.
Pulmonary Circulation
