- Arteries
- HOW THEY WITHSTAND PRESSURE
- Thick collagen wall provides strength and support
- Endothelium (Tunica Intima) is corrugated, so does not suffer any damage when stretched
- HOW THEY MAINTAIN PRESSURE
- Thick layer of smooth muscle, narrows and constricts the lumen.
- Thick layer of elastic tissue allows arteries to recoil back to their original shape
- HOW THEY WITHSTAND PRESSURE
