- Artery, Vein and Capillary (the heart)
- ARTERY
- blood travels away from the heart
- high pressure blood
- small lumen
- oxygenated blood (exception = pulmonary artery as it is carrying deoxygenated blood from the heart to the lungs so blood can become oxygenated)
- thick muscular wall to withstand high pressure blood
- elastic tissue allows artery to stretch when blood is forced into it
- protective collagen layer
- VEIN
- low pressure blood
- blood travels towards the heart
- large lumen
- thin muscle layer - wall not thick enough to hold round shape
- deoxygenated blood (exception= pulmonary vein as it is carrying oxygenated blood from the lungs to the heart)
- valve to stop backflow
- protective collagen layer
- CAPILLARY
- blood flows through organs/ tissues and it brings oxygen to every cell in the body
- very thin walls, one cell thick
- permeable
- ARTERY
