The ground substance of connective tissue is different from all of these fluids; it is the liquid medium through which these other fluid exchanges take place.
CONNECTIVE TISSUE. Connective tissue consists of cells separated by varying amounts of extracellular substance. In connective tissues cells typically account for only a small fraction of the tissue volume. The extracellular substance consists of fibres which are embedded in ground substance containing tissue fluid.Fibres in connective tissue can be divided into three types: collagen fibres, reticular fibres and elastic fibres.n connective tissues cells typically account for only a small fraction of the tissue volume.
