-I can distinguish the 3 different types of blood vessels on images and (microscope) photos.

Slide 2 - Slide

Which artery is oxygen-poor?
A
Aorta
B
Superior vena cava
C
Inferior vena cava
D
Pulmonary artery

Slide 3 - Quiz

Where can you find AV-valves?
A
Between the atria and ventricles.
B
Between the left ventricle and aorta.
C
Between the right ventricle and aorta.
D
Between the left ventricle and pulmonary artery.

Slide 4 - Quiz

Coronary arteries:
A
Bring O2 and nutrients to the heart.

Bring CO2 and waste products to the heart.
C
Take away O2 from the heart.

Slide 5 - Quiz

Homework b3

Slide 6 - Slide

B4: Blood vessels
-3 types
-Arteries (slagaders)
-Veins (aders)
-Capillaries (haarvaten).

Slide 7 - Slide

Arteries
-Blood flows away from heart.
-High blood pressure-->pulse.
-Thick walls to deal with pressure.
-Narrower inside diameter compared to veins.
-Blood flows quickly.


Slide 8 - Slide

Veins
-Blood flows towards heart.
-Low blood pressure-->no pulse.
-Thinner walls than arteries.
-Larger inside diameter compared to arteries.
-Have valves.


Slide 9 - Slide

Capillaries
-Between arteries and veins.
-Inside organs.
-Low blood pressure, because of large total volume.
-Blood flows slowly.
-Walls 1 cell thick, with openings.

Slide 11 - Video

Muscle pump
-Veins far away from heart need help.
-Muscles around vein help pump.
-Blood may 'hang around' arms and legs when muscles are inactive.

Slide 12 - Slide

next: video muscle pump
-From 1:20.

Slide 13 - Slide

Slide 14 - Video

Digestive system
-Digestive organs receive oxygen.
-Digestive organs release nutrients (but no oxygen).
-Veins carry nutrients to liver.
-Liver checks 
 harmful substances + stores nutrients.

Slide 15 - Slide

Capillaries have:
A
The thickest walls.
B
A thick wall, but not the thickest.
C
A wall made up of only 1 cell layer.
D
No wall.

Slide 16 - Quiz

To check victims to see if they are still alive, we check these blood vessels:

Slide 17 - Open question

Muscle pumps are needed at:
A
Veins.
B
Arteries.
C
Capillaries.
D
All of the above.

Slide 18 - Quiz

You can recognise veins on images, by looking at:
A
Colour: they are blue.
B
Colour: they are red.
C
Direction of flow: towards the heart.
D
Direction of flow: aways from heart.
