Cardiovascular System Part 1

We are snapping shut when you hear the "lub" sound through a stethoscope.

I am the side of the heart that controls the systemic circulation and receives oxygenated blood from the lungs to pump it to the rest of the body.

I am the term for relaxation of the myocardium.

I am a collagen fiber cord that prevents the valve from opening backward into the atrium.

I am the area in the middle of the thoracic cavity where the heart sits.

I carry blood toward the heart.

I am the fibrous sac in which the heart rests.

I am the term for contraction of the myocardium.

Oxygenated blood flows through me from the mother to a developing fetus.

I open when the pressure from the amount of blood in the right atrium forces me open, allowing blood to flow into the right ventricle.

I am the side of the heart that controls the pulmonary circulation, receiving deoxygenated blood and pumping it into the lungs.

I carry blood away from the heart.

I am the pacemaker of the heart.

We are snapping shut when you hear the "dub" sound through a stethoscope.

I am the largest vein in an animal's body, and in yours, too.

I am a measure of blood output from the left ventricle over a unit of time, usually 1 minute.

I close at specific times to prevent backflow of blood into the chamber.
