  • 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
