Q
Artery Vs Vein histology
A
Artery = Thick t. media (smooth muscle), usually round, may have elastin in t. media
* Vein = Thin wall, very little t. media, usually collapsed

Microscopically, what features would you expect to see in inflamed tissue?
Infiltrating immune/inflammatory cells
* Oedema
* Phagocytosed cells
* Fibrin
* Exudate
* Hyperaemia
27
inflamed tissue, as we can see Phagocytosed cells
* Hyperaemia
28
In the blood vessel pictured below (V), what cellular inflammatory response is evident? (Hint- look at the
periphery of the lumen).What chemical mediator might be causing this?
Margination/Pavementing (leukocytes only visible along the edge of the vessel wall). Histamine, chemokines, cytokines

Chronic inflammation (has mononuclear infiltrate)
