Case study: atrial septal defect
Slide 1 - Diapositive
Case study set up
You are being led through the case with questions and some theory.
In the end, you will have learned about the heart and the blood circulation by studying this case.
Slide 2 - Diapositive
General information
Arteries = slagaders = blood vessels that carry blood away from the heart
Veins = aders = blood vessel that carry blood towards the heart
Slide 3 - Diapositive
The pulmonary artery...
A
... goes from the lung to the heart
B
... goes from the heart to the lung
Slide 4 - Quiz
The aorta is a large artery. Which circulation is the aorta part of?
A
Pulmonary circulation
B
Systemic circulation
Slide 5 - Quiz
Pictures of the heart look like this. But... how to look at it?
A
The right side on the picture is also the right side in the body
B
The right side on the picture is the left side in the body
Slide 6 - Quiz
Our blood circulation is a 'double circulatory system'. What does it mean?
Slide 7 - Question ouverte
Introduction to ASD
ASD = atrial septal defect
This is a disorder where the two sides of the heart are connected, while they should be separated.
Slide 8 - Diapositive
ASD
On the right, you can see a GIF showing ASD. As said, this defect makes a connection between right and left but it should actually be closed.
First, you are going to study the healty situation. Then, you are going to think about this case.

The heart is separated into two halves. Why is this important?
Slide 11 - Question ouverte
00:52
Blood entering the right atrium comes from...
A
... the right ventricle
B
... the lungs
C
... the rest of the body
Slide 12 - Quiz
00:57
Is the blood deoxygenated or oxygenated when it enter the right atrium?
A
It is deoxygated because if comes from the body
B
It is oxygenated because it comes from the lungs
C
It is deoxgenated because it comes from the lungs
D
It is oxygenated because it comes from the body
Slide 13 - Quiz
01:04
Blood entering the left atrium comes from...
A
... the left ventricle
B
... the lungs
C
... the rest of the body
Slide 14 - Quiz
01:09
The left atrium contains oxygated blood. Through which artery does it go the body?
A
The pulmonary artery
B
The aorta
C
The left atrium
Slide 15 - Quiz
01:30
What is the function of heart valves?
Slide 16 - Question ouverte
Place the labels in the correct place in the picture.
Right atrium
Right ventricle
Left atrium
Left ventricle
Slide 17 - Question de remorquage
Overview
Study the picture on the right. Make sure you understand there the blood goes and where it comes from. The next question will be about this.
Slide 18 - Diapositive
What is the correct order, if we follow a oxygen molecule that enters the body? Start at 'the lungs'.
The left ventricle
The right ventricle
The left atrium
The right atrium
The aorta
The lungs
The rest of the body
Slide 19 - Question de remorquage
In this GIF, you can see the ASD and the blood flow.
Slide 20 - Diapositive
With ASD, blood can go from the left atrium to the right atrium and vice versa. With your knowledge of the blood flow and the heart, explain why this is a problem.
