Cardiovascular Quizlet

Superior Vena Cava

that carries deoxygenated blood from the upper half of the body to the heart's right atrium

Blood Pressure

the pressure of the blood in the circulatory system

Pulmonary Arteries

transporting de-oxygenated blood from the right ventricle to the lungs.

Veins

veins carry deoxygenated blood back to the heart.

Arteries

carry oxygenated blood away from the heart to the tissues

Coronary Artery

coronary arteries deliver blood to the heart muscle

Aortic Valve

Closes off the lower left chamber that holds the oxygen-rich blood before it is pumped out to the body.

Mitral Valve

It regulates blood flow from the upper left chamber (left atrium) into the lower left chamber (left ventricle), the heart's main pumping chamber.

Left Atrium

Its primary roles are to act as a holding chamber for blood returning from the lungs and to act as a pump to transport blood to other areas of the heart.

Aorta

The aorta distributes oxygenated blood to all parts of the body through the systemic circulation.

Left Ventricle

The left ventricle receives oxygenated blood from the left atrium via the mitral valve and pumps it through the aorta via the aortic valve, into the systemic circulation.

Right Atrium

The right atrium is one of the two atria of the heart, which function as receiving chambers for blood entering the heart.

Right Ventricle

The right ventricle is the chamber within the heart that is responsible for pumping oxygen-depleted blood to the lungs.

Inferior Vena Cava

inferior vena cava is a large vein that carries de-oxygenated blood from the lower body to the heart.

Tricuspid Valve

prevent back flow of blood into the right atrium.

Pulmonary Valve

pushing blood out of the heart and into the artery.

Pulmonary Veins

receive oxygenated blood from the lungs and drain into the left atrium of the heart.
