Congestion
* Congestion of capillary beds closely related to the development of oedema (congestion & oedema commonly occour together).
* Chronic passive congestion leads to hypoxia due to stasis of poorly oxygenated blood, resulting in parenchymal cell degeneration or death.
* Capillary rupture at sites of chronic congestion may cause small foci of haemorrhage.
* Breakdown & phagocytosis of red cell debris can result in small clusters of haemosiderin-laden macrophages.
