1. True
2. False

How many chambers does the heart have?

1. 2
2. 4
3. 6
4. 8

This type of muscle makes your heart pump.

1. smooth muscles
2. voluntary muscles
3. involuntary muscles
4. cardiac muscles

Pictures of the heart look like this. But... how to look at it?

1. The right side on the picture is also the right side in the body
2. The right side on the picture is the left side in the body

When blood flows back to the heart, where does it go first?

1. into the valves
2. into the atria
3. into the ventricles
4. into the septum

Which valve is at the beginning of the left (big) bloodvessel?

1. Pulmonary valve
2. Bicuspid valve
3. Tricuspid valve
4. Aortic valve

How is it possible that blood only flows one way?
Because:

1. of the blood pressure
2. blood cells know how to flow
3. there are valves
4. how the heart contracts

Which valves are located between the atria and ventricles?

1. Tricuspid valve & bicuspid valve
2. Bicuspid valve & aortic valve
3. aortic valve & pulmonary valve
4. Pulmonary valve & tricuspid valve

The heart

-left side pumps oxygen rich 

  blood into the systemic 

  circulation 

-right side pumps oxygen poor

  blood into the pulmonary 

  circulation

Which part of the circulatory system prevents blood from flowing back?

1. Veins
2. Arteries
3. Valves
4. Atria

When is blood 'deoxygenated'?

1. When the concentration oxygen is low and the concentration carbon dioxide high
2. When the concentration of oxygen is high and the concentration of carbon dioxide high

Through which side of the heart flows oxygenated blood?

1. Right side
2. Left side

When blood goes to the heart, it flows into the ventricles first.

1. Correct
2. False

Describe the pulmonary circulation and the systemic circulation

The systemic circulation makes sure your kidneys get oxygenated blood

1. True
2. False

Which type of bloodvessel has a thick and muscular wall?

1. Veins
2. Arteries
3. Capillaries
4. All of them

Veins contain _______ to prevent blood from flowing back

1. Openings
2. Capillaries
3. Valves

(1)____________ transports blood to the heart.
(2)____________ transports blood away from the heart
