Summary Introduction
To review:
The two major components and the subclasses of each component of the extracellular matrix.
Introduction:
Connective tissues are the most dominating type of tissues in the body. Majority of the skin is made up of connective tissues. These connective tissues are categorized into four major classes: connective tissue proper, bone tissues, cartilage, and blood. These tissues serve very important rules. They help the body in supporting and binding procedures, in the protection, insulation process, and in the transportation of the various substances inside the body.
