Slide 1 - Slide

What is the name of part S
Red blood cell
White blood cell
Blood plasma

Slide 2 - Quiz

What is the correct order, if we follow a oxygen molecule that enters the body? Start at 'the lungs'.
The left ventricle
The right ventricle
The left atrium
The right atrium
The aorta
The lungs
The rest of the body

Slide 3 - Drag question

What is the name of part 10?
Superior vena cava
Pulmonary artery
Pulmonary veins

Slide 4 - Quiz

Blood flow
Left and right are separate, but contract at the same time.

Atria need to contract before the ventricles

Slide 5 - Slide

cardiac cycle
- atria contract, blood flows into 
   ventricles (atrial systole)

- ventricles contract, blood 
   flows into aorta and pulmonary 
   artery (ventrical systole)

- Heart relaxes, blood flows 
   into atria (diastole)

Slide 6 - Slide

How does the cardiac cycle go?
Atria contract, cardiac pause, ventricles contract
Ventricles contract, cardiac pause, atria contract
Atria contract, ventricles contract, cardiac pause
Ventricles contract, atria contract, cardiac pause

Slide 7 - Quiz

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 8 - Drag question

How to control blood flow
Two options to adjust:

1. Pump faster/slower --> adjust heart rate
2. Pump with more or less force --> adjust blood pressure

Slide 9 - Slide

Heart rate
Heartbeat sound consists of two parts: lub and dub

Slide 10 - Slide

Measuring heart rate/pulse
1. find your pulse
2. count during the 30 seconds of the timer
3. multiply by 2 because we measure pulse per minute

Slide 11 - Slide

What is your heart rate?

Slide 12 - Mind map

Electrical control

Slide 13 - Slide

What happened this weekend?

Slide 14 - Mind map

Heart fibrillation 
The electrical communication in the heart is not following the correct order and path. This cause the parts to contract in the wrong order/not powerful

Slide 15 - Slide

What to do?
Use a defibrillator to 'reset' the heart rhythm

Slide 16 - Slide

Slide 17 - Video

Worksheet heart rate on the Classroom
