- Types of Blood Vessels
- Veins
- Take blood TO the HEART and AWAY from ORGANS
- Blood travels at LOW PRESSURE so veins have VALVES to prevent back flow
- Blood inside the veins is usually de-oxygenated
- Arteries
- Blood travels AWAY for the HEART and TOWARDS the ORGANS
- Travels at HIGH PRESSURE
- Blood inside the arteries is usually OXYGENATED
- Arteries have thick muscular walls to withstand the high pressure
- Capillaries
- Microscopic in size
- Only one cell thick so allow substances to be exchanged between blood and body cells
- Veins
