• Biologie
• Middelbare school
• vwo
• Leerjaar 3

Planning for today 

• Welcome 
• video + questions
• explaining 3.6
• making assignments 
• checking test previous lesson 
• Test: basic 1,2,3 and 6
• next lesson: Heart 

Learning goals:

• You can name different cardiovascular diseases and explain what happens and where.
  
• You are able to explain your expertise and educate your classmates.

Pay attention to the video:

- What is diastolic pressure?

- What is systolic pressure?

- What is a healthy blood pressure?

- Why is it bad when it is too high or too low?

0

2 sides of the heart work together

Diastole

-Heart muscles are relaxed

-Blood flows into the atria from the veins

Systole (atria or ventricles)

Heart muscles contract

1. Atria contract (DA...)
- blood forces into the ventricles 

2. Ventricles contract (DUM...)
- blood forced into the arteries 

heart attack

• One or more bloodvessels around the heart muscle (coronary arteries) is blocked
• Parts of the heart stop beating or start beating irregularly
• Blockage = called thrombosis

Stroke

• One or more bloodvessels to the brain are blocked.
• Parts of the brain get starved of oxygen and can be damaged permanently.

Risk factors

-inherited genes

-age

-sex (men have a higher chance)

-eating fatty foods

-being over weight

-smoking

-taking little or no exercise

BAC

• Blood alcohol content
• The level of alcohol content in the bloodstream
• Depends on body weight and how long the alcohol has been in the body
• 30 minutes to absorb alcohol in bloodstream and 60 minutes to break it down.

Long-term effect of alcohol

• Disrupts the development of the brain
• Disrupts hormone balance
• leads to memory loss
• leads to damage in liver, stomach and heart 

Binge drinking

• drinking too much alcohol in a short period of time
• Sudden high concentrations of alcohol can severly damage the brain
• may increase the likehood of having a stroke 

basic 3.6

Make assignment 1,2,3a/b, 4c, 5, 6, 8, 9

Blood pressure

1.  What is blood pressure?

2. What are the effects of low and high blood pressure?

3. What causes high blood pressure?

4. What influence does exercising and rest have on the blood pressure?

5. What kind of long term health risks can high blood pressure cause?

Arteriosclerosis

1.  What is Arteriosclerosis?

2. How does a blood vessel change on the inside? (use a image)

3. What influence does Arteriosclerosis have on blood pressure?

4. A tissue gets oxygen and nutrients. What happens with tissue when a blood vessel is damaged?

5. Name 3 things that cause Arteriosclerosis and what people can do to prevent it.

Heart attack

1. What is a heart attack?

2. How can a heart attack change the heart? (use image).

3. What blood vessel usually plays a role in a heart attack?

4. What can doctors do to repair a damaged blood vessel during/after a heart attack?

5. How can a healthy lifestyle prevent heart attacks (name 4 examples)

Stroke

1. What is a stroke? Name different types.

2. How can a stroke change the brain? (use an image)

3. How can a stroke impact the way a human functions?

4. How can you see a person just had a stroke?

5. How can a healthy lifestyle possibly prevent a stroke? Name 3 examples.

Alcohol

1. What exactly is alcohol?

2. What effect has alcohol on how you function?

3. How can short term effects of alcohol be dangerous?

4. What long term health problems can alcohol cause?

5. What is alcohol poisoning?

A doctor measures the blood pressure in a

1. vein
2. artery
3. capillary

What is the consequence of arteriosclerosis for a blood vessel?

1. The vessel becomes narrower and stiffer
2. The vessel becomes wider and too much blood starts to flow
3. A lower blood pressure because the blood cannot flow easily

what effect does arteriosclerosis have on the blood pressure?

1. The bloodpressure will lower, because the blood can flow easily through the arteries.
2. The blood pressure will rise, because the blood can flow easily through the artery.
3. The bloodpressure will lower, because its harder for the blood to flow through the arteries.
4. The blood pressure will rise, because its harder for the blood to flow through the arteries.

which blood vessel gets clogged during a heart attack?

1. aorta
2. coronary vein
3. coronary artery
4. pulmonary artery

Wat is alcohol voor stof?

1. een opwekkende stof
2. een verdovende stof
3. een ontsmettingsmiddel
