Heart - Valves


We just learned about how the blood flows through the ventricles, atriums, veins and arteries.

In between each of these areas is something called a valve which opens and closes to let the blood out or keep it in.

Heart - Blood Flow


We just learned about the Pulmonary Artery

We've now learned about all of the arteries and veins that pump blood all over the body.

The part of the body that does the pumping is the heart, which has 4 chambers that we've already learned about.

Deoxygenated blood comes into the Right Atrium and then goes to Right Ventricle.
The Right Ventricle pushes the blood to the lungs to get oxygen, then the oxygenated blood comes into the Left Atrium.
The blood then goes into the Left Ventricle which sends the blood to all parts of the body, and it comes back to the Right Atrium where we started.

So it goes Right Atrium, Right Ventricle, Lungs, Left Atrium, Left Ventricle, Body, Right Atrium.

Right Ventricle


We just learned that the right atrium fills up with deoxygenated blood from the body.

After that the blood goes into the right ventricle which pumps the blood out of the heart and over to the lungs to get filled up with oxygen.

Right Atrium


We just learned about the jugular vein that brings deoxygenated blood from the head and neck down toward the heart.

All of the arteries in the push blood away from the heart, and all of the veins bring blood back toward the heart.

We learned about the superior and inferior vena cava that brings blood back into the heart.
That goes right into the right atrium a chamber in the heart that fills up with deoxygenated blood.

Aorta


We've learned that oxygenated blood goes comes into the heart at the left atrium which is part of the heart, and then goes to the left ventricle which pushes the blood to all the parts of your body.

The big tube that the left ventricle pushes the blood to first is called the aorta.

The aorta is a big long tube that goes up from your heart, then turns and goes downward all the way down to your hips area.

Left Ventricle


We've learned that oxygenated blood goes from the pulmonary veins to the left atrium which is part of the heart.

The left atrium sends the blood into a large area of the heart called the left ventricle.

The left ventricle takes in all of the fresh blood full of oxygen, and pushes it all the way out to every part of your body.
From the tips of your toes to your fingers and ears, the blood carrying the oxygen that your body needs is pumped out by the muscles of the left ventricle.

Left Atrium


We've learned that our blood gets filled up with good oxygen in the capillaries by the lungs, and then goes through tubes called the pulmonary veins toward the heart.

The oxygen filled blood, sometimes called oxygenated blood, enters the heart at a place called the left atrium.

The heart is divided up into four parts, called chambers, and the atrium is one of those chambers.
