Parts of the HeartAtria (or atrium for plural)

The heart has 2 atriums, or chambers, on the right and left side of the heart. They fill with deoxygenated blood that returns from the body and oxygenated blood that returns from the lungs.

VentriclesThe heart also has 2 ventricles, one on the right

side and one on the left side of the heart. Ventricles are bigger than atria and stronger too because their job is to push the blood out to the rest of the body and lungs.

Parts of the Heart Cont…Septum

The thick wall of muscle that separates the left side from the right side of the heart.

4 ValvesMitral Valve (or Bicuspid): is located between

the left ventricle and left atrium.Tricuspid Valve: is located between the right

ventricle and right atrium.Both valves allow blood to flow from the

atria to the ventriclesAortic Valve and Pulmonary Valve (also called

semilunar valves): controls the blood flow away from the heart

Function of the HeartYour heart is a muscle that continuously

works to pump blood throughout your body. It provides your body with the oxygen and nutrients it needs while also carrying away waste products.

The right side of the heart receives blood from the body and the left side of the heart pumps blood throughout the body.

The valves act as check valves or one way doors to regulate the blood flow and direction of flow.

Lub-DubLub Dub is the sound your heart makes with each beat. Lub is heard when Tricuspid and Mitral (Bicuspid) value close. Dub is the sound that is heard when the Aortic and Pulmonary Valves close. A stethoscope is used by physician’s to listen to your heart.

Click on image below!A heart murmur is heard when a valve is unable to close all the way.

That's long enough to go around the world more than twice! A child’s heart is about the size of a clenched fist. An adult’s heart is about the size of two fists.The heart beats about 100,000 times each day.Blood is about 78% water.
