Connective tissue is made up of cells and extracellular matrix. The extracellular matrix is made up of fibres in a protein and polysaccharide matrix, secreted and organised by cells in the extracellular matrix.
The intercellular material, or matrix, is produced by the cells and gives the tissue its particular character. Connective tissue is diversified in function and may be divided into four categories according to the type of matrix.In connective tissue proper (which forms the framework for most organs) the matrix is soft.n animals, a tissue that develops from the mesenchyma and performs supportive, nutritive (trophic), and protective functions. A structural characteristic of connective tissue is the presence of well-developed intercellular structures (fibers and ground substance).
