Q

What is the general structure of blood vessels?

A

Tunica intima:

  • Endothelium + subendothelial layer of loose connective tissue
  • Longitudinal arrangement

Tunica media:

  • Concentric layers of smooth muscle cells
  • Collagen + elastic fibres + proteoglycans
  • Lamina elastica interna and externa
  • Pericytes - ‘media’ of capillaries and post capillary venules

Tunica adventitia:

  • Longitudinally oriented collagen and elastic fibres
  • Vasa vasorum - penetrate from adventitia to media
  • Lymphatic capillaries - media of veins and advantitia of arteries
