EM 246 Artery and Vein

Muscular Artery and Medium Vein

Scanning electron micrograph (SEM) of a muscular artery and a medium vein in the liver.

  • Muscular Artery
    • Tunica Intima (red) - inner, thin layer that is difficult to distinguish from tunica media
    • Tunica Media (red) - middle layer composed of smooth muscle
    • Tunica Adventitia (yellow) - outer layer of dense irregular connective tissue
  • Medium Vein (blue) - thinner wall in which the individual layers cannot be identified in this specimen
  • Loose Connective Tissue (tan)

Major differences between arteries and veins:

  • Lumen of veins are larger than for arteries (not obvious in this specimen because the vein is partially collapsed
  • Tunics are thinner and less organized in veins
