Infarctions are divided into two types according to the amount of [[blood]] present:
# [[White infarction]]s ([[anemic infarct]]s) affect solid organs such as the [[spleen]], [[heart]] and [[kidneys]] wherein the solidity of the [[tissue (biology)|tissue]] substantially limits the amount of nutrients ([[blood]]/[[oxygen]]/[[glucose]]/[[fuel]]) that can flow into the [[area]] of [[ischaemic]] [[necrosis]]. Similar [[Vascular occlusion|occlusion]] to [[blood flow]] and consequent [[necrosis]] can occur as a result of severe [[vasoconstriction]] as illustrated in severe [[Raynaud's phenomenon]] that can lead to irreversible [[gangrene]].
# [[Red infarction]]s ([[hemorrhagic infarct]]s) generally affect the [[lung]]s or other loose organs ([[testis]], [[ovary]], [[small intestines]]). The [[Vascular occlusion|occlusion]] consists more of [[red blood cell]]s and [[fibrin]] strands. Characteristics of red infarcts include:
#* occlusion of a [[vein]]
#* loose tissues that allow [[blood]] to collect in the [[infarcted]] zone
#* tissues with a dual [[circulatory system]] (lung, small intestines)
#* tissues previously congested from sluggish venous outflow
#* [[Reperfusion injury|reperfusion]] ([[injury]])<ref>{{cite journal |pages=654–7 |doi=10.1038/365654a0 |title=Prevention of lung reperfusion injury in rabbits by a monoclonal antibody against interleukin-8 |year=1993 |last1=Sekido |first1=Nobuaki |last2=Mukaida |first2=Naofumi |last3=Harada |first3=Akihisa |last4=Nakanishi |first4=Isao |last5=Watanabe |first5=Yoh |last6=Matsushima |first6=Kouji |journal=Nature |volume=365 |issue=6447 |pmid=8413628|bibcode=1993Natur.365..654S |s2cid=4282441 }}</ref> of previously [[ischemic]] tissue that is associated with [[Reperfusion injury|reperfusion]]-related [[diseases]],<ref>
