Key Stage 3
Meaning
An vein is a blood vessel which carries blood to the heart.
Key Stage 4
Meaning
An vein is a blood vessel which carries low pressure blood to the heart.
Adaptations of Veins
- Veins have a thin layer of muscle because the blood is a low pressure.
- Veins have few layers of elastic tissue as the blood is a low pressure.
- Veins have valves in them to stop the blood flowing in the wrong direction because it is such a low pressure.
- Veins often pass between muscles which work with the valves by contracting to force the blood through the vein.

About Veins
- Most, but not all, veins carry deoxygenated blood.
- The pulmonary vein carries oxygenated blood from the lungs to the heart.
