===Areolar tissue===
'''Areolar tissue''' ({{IPAc-en|ə|ˈ|r|iː|ə|l|ər}} or {{IPAc-en|ˌ|ɛər|i|ˈ|oʊ|l|ər|,_|ˌ|ær|-}}{{refn|{{MerriamWebsterDictionary|access-date=2016-01-21|Areolar}}}}{{refn|{{Cite dictionary |url=http://www.lexico.com/definition/Areolar |archive-url=https://web.archive.org/web/20200322184335/https://www.lexico.com/definition/areolar |url-status=dead |archive-date=2020-03-22 |title=Areolar |dictionary=[[Lexico]] UK English Dictionary |publisher=[[Oxford University Press]]}} }}) is a common type of loose connective tissue (and the most widely distributed type of [[connective tissue]] in vertebrates). It is so-named because its fibers are far enough apart to leave ample open space for [[interstitial fluid]] in between (''[[wikt:areola#Noun|areola]]'' is Latin for a "little open space"). It is strong enough to bind different tissue types together, yet soft enough to provide flexibility and cushioning. It exhibits interlacing,<ref>{{DorlandsDict|eight/000109046|areolar tissue}}</ref> loosely organized fibers,{{citation needed|date=May 2015}} abundant blood vessels, and significant empty space filled with interstitial fluid. Many adjacent [[epithelium|epithelial]] tissues (which are avascular) get their nutrients from the interstitial fluid of areolar tissue; the [[lamina propria]] is areolar in many body locations. Its fibers run in random directions and are mostly collagenous, but elastic and reticular fibers are also present. Areolar tissue is highly variable in appearance. In many [[serous membrane]]s, it appears as a loose arrangement of collagenous and elastic fibers, scattered cells of various types; abundant [[ground substance]]; numerous blood vessels. In the skin and mucous membranes, it is more compact and sometimes difficult to distinguish from [[dense irregular connective tissue]].
