This Lesson:

Heart Structure & Function

What can you tell me about the heart & the circulatory system?

This Lesson Learning Goals:

• To be able to identify and label the main structures of the heart.
  
• To be able to trace the path of blood through the human heart and the general circulation.
  
• To understand how the structures of the heart are related to the function of the heart.
  

How?

1. Film: heart valve disease & functions + quiz vragen

2. Explanation + note taking the circulation of blood around the body. 

3. Film: heart function & blood flow through the heart.

4. Quiz heart & circulation

5. Exercise: structure & function of the heart.

6. Quiz: structure & function of the heart.

7. Homework for week 12.

Context of Lesson:

 

Many diseases of the heart can lead to a patient needing a whole new heart (transplant) or replacement of part of the heart.

Heart valves disease is an example of when a part of the heart needs to be replaced.

Some heart valve diseases are inherited and can be common in some families.

Diseases of the heart valves can tell us a lot about the function of the heart and the blood flow through the heart.

Valve disease can mean the valves do not open properly. This also means......?

1. Increases blood flow through the heart
2. Reduce blood flow throught the heart.
3. Blood flow through the heart is stopped
4. Blood flows the wrong way.

If the valves do not close, they are leaky. What happens to blood flow?

1. Blood flow is increased.
2. Blood flow is not fast enough.
3. Some blood flows backwards.
4. Blood flows to all 4 chambers of the heart.

To understand more about blood flow through the heart we first need to zoom out and look at the blood flow through the body:

Use the diagram provided to make notes as we go through the circulatory system.

Use all the keywords provided.  

Pulmonary (lung) circulation:

Heart - lungs - heart

Systemic (body)

Heart - body - heart

Systemic circulation

Lung circulation 

(pulmonary)

Delivery oxygen to all the bodies cells.

Take oxygen into blood

Deliver carbon dioxide to the lungs

Take up carbon dioxide into the blood

Exercise 2: heart function. 

Use hand out. 

• Fill in blanks. 
• 10mins max.
• Resource:
• Reader in google classroom. 

Which side of the heart caries oxygen rich blood?

1. Right side
2. Left side

The left side of the heart receives oxygen rich blood from the lungs.

How is carbon dioxide carried to the lungs?

1. Via the aorta
2. Via the pulmonary artery
3. Via the vena cava
4. Via the pulmonary vein

The pulmonary artery is the only artery to carry blood rich in CO2 and poor in oxygen. 

Where is oxygen rich blood found in the heart?

1. 4 & 5
2. 3
3. 5
4. 2 & 3

Oxygen rich blood return via the pulmonary veins to the left side of the heart. 

Welke numbers pump the blood to the lungs and body?

1. 5 & 3 left & right ventricles
2. 4 & 2 Left & right atria
3. 5 & 3 Left & right atria
4. 4 & 2 Left & right ventricles

Which part of the heart receives carbon dioxide rich blood from body?

1. 4 (right atrirum)
2. 4 (left ventricle)
3. 2 (left atrium)
4. 2 (left ventricle)
