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.

A

Slide 5 - Quizvraag

To which circulation do the coronary arteries and veins belong?

Slide 7 - Open vraag

Case 2: arrythmia

Slide 8 - Tekstslide

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 - Tekstslide

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
