What are the Characteristics of Connective Tissue?
Connective tissue is diverse and consists of cells embedded in an extensive extracellular matrix composed of protein fibers (collagen, elastin) and ground substance. This tissue type provides structural support, defends against infection, and connects different tissues and organs. Major cell types include fibroblasts, macrophages, and adipocytes. Specialized connective tissues include bone, cartilage, and blood.
