Coronary blood vessel
Like everything else in the body, the heart needs oxygen. It gets oxygen through its own blood vessels. Those come from the aorta and are called coronary arteries. When has brought oxygen to the heart muscle, the deoxygenated blood goes back the right atrium. The vessels that bring blood back are called coronary veins.

Slide 4 - Slide

Are coronary arteries carrying oxygen-rich or oxygen-poor blood?

Slide 5 - Quiz

To which circulation do the coronary arteries and veins belong?
The pulmonary circulation
The systemic circulation

Slide 6 - Quiz

Look at the picture. You see the coronary artery being blocked causing a heart attack. Explain in your own words what happens with a heart attack.

Slide 7 - Open question

Case 2: arrythmia

Slide 8 - Slide

Heart contaction
Contraction = tensing the muscle

Heart contraction happens in different phases. This causes the blood to flow from atria to ventricles, into the arteries.

Slide 9 - Slide

Put the texts underneath the corresponding picture.
Cardiac pause - heart fills with blood
Atria contract
Cardiac pause - heart fills even more with blood
Ventricles contract
Blood flows into arteries

Slide 10 - Drag question
