Aorta: The largest arteries in body which carries blood from left ventricle to body.
Arteries: Blood vessels that carries away blood away from heart.
Atrium: Two upper chambers of the heart.
Blood Pressure: Pressure made by blood against the walls of blood vessels.
Capillaries: Narrow blood vessels where blood and cells exchange substances.
Cardiovascular System: The body system that include heart, blood vessels, and blood. Also, called us circulatory system.

Diffusion: A process that molecules move higher area concentration to lower area concentration.
Heart: A muscular organ, which is made out of cardiac muscle (muscle that is working all the time), pump blood through the body.
Hemoglobin: An iron-containing protein which connects chemically with oxygen.
Lymph: A fluid which is in lymphatic system.
Lymph Node: A organ that filter lymph.
Lymphatic System: A body system that gives back fluid which entered to lymphatic system. Part of circulatory system.
Pacemaker: Group of heart cells located on right atrium which makes heart muscle to contract by sending out signal.
Plasma: Liquid part of blood.
Platelet: Cell fragment which plays important part to make blood clots.
Pulse: Expansion and relaxation of artery wall.
