  27. 27. Blood <ul><li>Blood is the fluid which runs within the blood vessels, and is the most atypical connective tissue, however it does not connect things or give mechanical support. It is classified as a connective tissue due to the fact that it develops from mesenchyme and consists of blood cells. </li></ul><ul><li>Link: </li></ul><ul><li>http://en.wikipedia.org/wiki/Blood </li></ul>Tissues
