Artery
Vein
Capillary

2

What is the role of arteries?

Transport blood away from the heart

3

What is the blood pressure of arteries?

High blood pressure
Pulse can be felt

4

What is the blood like in an artery?

Blood flow is rapid.
Low blood volume.
Blood is oxygenated. (except pulmonary)

5

What is the structure of an artery?

Thick wall
Small lumen
No semi-lunar valves
Elastic and smooth muscle tissue
Tunics media thick

6

What is the role of veins?

Transport blood towards the heart

7

What is the blood pressure in veins?

Blood pressure low
No pulse can be felt

8

What is the blood like in a vein?

Blood flow slow
High blood volume
Deoxygenated blood

9

What is the structure of a vein?

Thin wall
Large Lumen
Semi-lunar valves
Few elastic fibres/ Slightly muscular
Tunica media thin

10

What is the role of semi-lunar valves in veins?

Prevent the back flow of blood

11

What is the role of capillaries?

Link aertrtioles to venules
Site of exchange between blood and tissue.

12

What is blood pressure of capillaries?

Falling blood pressure
No pulse felt

13

What is the blood in a capillary like?

Blood flow is slow
High blood volume
Mix of oxygenated and deoxygenated blood

14

What is the structure of a capillary?

Very thin wall- 1 cell thick
No semi-lunar valves
No elastic fibres- only squamous endothelium
No Tunica media

15
