What is Connective tissue?
'''Connective tissue''' is a fibrous [[tissue]].<ref>{{DorlandsDict|eight/000109061|Connective tissue}}</ref> It is one of the four traditional classes of tissues (the others being [[epithelium|epithelial]], [[muscle]], and [[nervous tissue]]). Connective tissue (CT) is found throughout the body. It has 3 main components; [[cell]]s, [[fibre]]s, and extracellular matrix. Connective tissue makes up a variety of physical structures including, [[tendon]]s, [[blood]], [[cartilage]], [[bone]], [[adipose tissue]], and [[Lymphatic system|lymphatic tissue]]. CT is classified into three subtypes: embryonic CT, proper CT, and special CT. [[Collagen]] is the main [[protein]] of connective tissue in [[animal]]s and the most abundant protein in [[mammal]]s, making up about 25% of the total protein content.<ref>{{Cite journal|year=2002|author=Di Lullo, G.
