Heart and blood vessels

Which parts of the heart do you already know?

Parts of the heart

The blood vessels

Arteries - veins - cappilaries

Heart beat in 3 stages

Atriums contract

Ventricles contract

Pause

The heart pumps oxygen rich blood into the?

1. Superior vena cava
2. Pulmonary arteries
3. Aorta
4. Aorta and pulmonary arteries

Thanks to the valves, the blood doesn't flow back into the...

1. Ventricles
2. Atriums

These cells make sure the heart beats a certain amount of times a minute.

1. Sinus cells
2. Brain stem
3. Aorta
4. Red blood cells

The heart receives oxygen rich blood from the ...

1. Pulmonary veins
2. Pulmonary arteries
3. Coronary arteries/veins
4. Aorta

The right order in heartbeat is

1. Ventricles - atriums - pause
2. Atriums-Ventricles - pause
3. Pause - atriums - ventricles

2. This happens in veins
3. This happens in capillaries
4. All answers are correct

1. 9 = valve
2. 9 = aortic valve
3. 9 = pulmonary valve
4. All answers are wrong

Sinus cells - nerve cells that initiate the heart beat

Revision
