Animal tissues


Connective tissue is a main component of the animal body. It has been regarded as a supporting tissue because it connects, protects, and keeps together the organs of the body. Furthermore, it allows the communication between different parts of the body. For example, the molecules absorbed by epithelia must cross the connective tissue before they reach other tissues. Connective tissues are a diverse group with some common features. The most important one is that they show a remarkable extracellular matrix, which is a scaffolding made up of collagen, elastin, glycoproteins, proteoglycans, glycosaminoglycans, and other molecules. The type and proportion of these components set the structural, mechanical and biochemical properties of the different connective tissues. Extracellular matrix features and cell types define a variety of connective tissues. Although the classification may depend on the author, connective tissues are generally grouped as follow:
