Final answer:
Connective tissue is characterized by a diverse range of cells, a ground substance, and protein fibers, all of which contribute to its functionality such as providing support, elasticity, and protection for other tissues and organs within the body.
Step-by-step explanation:
Connective tissue (CT) structural characteristics include a variety of cells, large amounts of amorphous ground substance, and protein fibers. These three components are intertwined within a matrix that defines the tissue and contributes to its function in the body. The matrix's composition can range from fluid to mineralized and solid, as found in bones, supporting varying functions such as support, elasticity, and protection. For instance, in bones, the calcified matrix provides support, and in blood, the fluid matrix is involved in transport. Connective tissue proper, consisting of loose and dense variations, contains fibers that are either loosely arranged or densely packed, providing flexibility or tensile strength, respectively. Supportive connective tissue like bone and cartilage lends structural integrity to bodily frameworks, while fluid connective tissue like blood and lymph circulates nutrients and cells throughout the body.
