Cardiovascular

Super Vena Cava

A large vein carrying deoxygenated blood from the head, arms, and upper body into the heart.

Inferior Vena Cava

A large vein carrying deoxygenated blood from the lower body into the heart.

Coronary Artery

An artery supplying blood to the heart.

Arteries

Any of the muscular-walled tubes forming part of the circulation system by which blood (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body.

Veins

Any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.

Chordae Tendineae

Are cord-like tendoms that connect th e papillary muscles to the tricuspid valve and the mitral valve in the heart.

Pulmonary Veins

Are large blood vessels that receive oxygenated blood from the lungs and drain into left atrium of the heart

Pulmonary Arteries

Carries deoxygenated blood from the heart to the lungs. It is one of the only arteries that carries deoxygenated blood.

Aortic Valve

One of the four valves in the heart, the aortic valve is located between the left ventricle and the aorta, which is the largest artery in the body. Valves maintain one-way blood flow through the heart.

Pulmonary Valve

One of the four valves in the heart, which stands at the opening from the right ventricle in the pulmonary artery trunk. The pulmonary valve moves blood toward the lungs and keeps it from sloshing back from the pulmonary artery into the heart.

Septum of the heart

That portion of the septum that separates the two upper chambers.

Left Ventricle

The left lower chamber of the heart that receives blood from the left atrium and pumps it out under high pressure through the aorta to the body.

Right Ventricle

The lower right chamber of the heart that receives deoxygenated blood from the right atrium and pumps it under low pressure into the lungs via the pulmonary artery.

Aorta

The main artery of the body, supplying oxygenated blood to the circulatory system. In humans it passes over the heart from the left ventricle and runs down in front of the backbone.

Blood Pressure

The pressure of the blood in the circulatory system, often measured for diagnosis since it is closely related to the force and rate of the heartbeat and the diameter and elasticity of the arterial walls.

Right Atrium

The right upper chamber of the heart. The right atrium receives deoxygenated blood from the body through the vena cava and pumps it into the right ventricle which then sends it to the lungs to be oxygenated.

Tricupsid Valve

The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, between the right atrium and the right ventricle. The function of the valve is to prevent back flow of blood into the right atrium.

Left Atrium

The upper right chamber of the heart. The left atrium receives oxygenated blood from the lungs and pumps it down into the left ventricle which delivers it to the body.

Mitral Valve

The valve between the left atrium and the left ventricle of the heart, consisting of two tapered cusps.
