Lesson 6 - The Heart

The Chambers (click the hot spots for more information)

The Left Ventricle collects blood from the Left Atrium and pushes the blood up through the aorta.

The Left Atrium collect the blood from the lungs. 

The Right Ventricle collects the blood from the Right Atrium and passess the blood through the pulmonary artery.

The Right Atrim collects the blood that flows back to the heart from the body. 

Seperated into left and right.

The top sections are called atriums.

The bottom sections are called ventricles. 

The Valves (click the hot spots for more information)

Bicuspid valve - allows blood to travel from the left atrium to the left ventricle, but stops the blood from returning back up to the atrium. 

The Aortic Valve allows blood to flow from the left verticle through the aorta, but stops it from flowing back to the left ventricle. 

The Pulmonary valve, allows blood to travel from the right ventricle up through the pulmonary artery, but stops it from flowing back into the right ventricle. 

Tricuspid Valve - lets blood flow from the right atrium to the right ventricle, but stops the blood from going back into the right atrium.

Between the different chambers and tubes of the heart there are valves, these are like little doors that stop the blood from flowing the wrong way around the heart.

Using the infromation below place the arrows on the heart showing the direct of  deoxygenated blood flow around the heart. 

This is blood that has travelled aoround the body dropping off oxygen to muscles and has now come back to the heart to be passed to the lungs to pick up some more oxygen.

Blue show blood without oxygen (deoxygenated) Use the arrows to show the direction of blood flow.

Deoxygenated blood passes through these blood vessels, valves and parts of the heart:

Superior vena cava

right atrium

Tricuspid valve

Right ventricle

Semilunar / Pulmonary valve

Pulmonary artery

Lungs

Using the infromation below place the arrows on the heart showing the direct of  oxygenated blood flow around the heart. 

This is blood that has travelled to the heart from the lungs after picking up oxygen, it passess through the heart and travels around the body to deliver oxxygen to our muscles.

Red show blood with oxygen (oxygenated)

Use the arrows to show the direction of blood flow.

Oxygenated blood passes through these blood vessels, valves and parts of the heart:

pulmonary vein

left atrium

Bicuspid / mitral valve

left ventricle

Semilunar / aortic valve

aorta

body

What role does the heart play in the circulatory system?

1. Gives us a heart beat
2. Helps us move
3. Digests food
4. Pumps blood

How many chambers are there in the heart?

What are the top chambers of the heart known as?

1. Pulmonry Valve
2. Aorta
3. Ventricle
4. Atrium

Deoxygenated blood passess from the heart to the ____________

1. Atriums
2. Heart
3. Lungs
4. Body
