ARTERIES

2. blood flow with pressure.
3. arteries carry blood away from heart to the body organs. Heart > organs.
4. carry oxygen rich blood from heart to all parts of the body (except pulmonary artery)

VEINS
1. have thinner and less elastic walls.
2. blood flow is slow (low pressure)
3. veins collect blood from organs and carry it towards the heart. Organs> heart
4. carbon dioxide rich blood from all parts of the body to heart. (except pulmonary vein)
5. have valves which allow blood to flow only towards the heart.

CAPILLARIES
1. extremely thin walls.
