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 3 - Slide

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.

Case 2: arrythmia

Slide 5 - 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 6 - Slide

Blood flows into arteries
