8.13 : Functions of Connective Tissues

Connective tissues perform a broad range of functions in the body. Their primary function is to connect and link different tissues in the body and act as packaging material between tissues. The areolar tissue, a connective tissue prototype, commonly cements various tissue types in diverse body organs. In contrast, adipose tissue cushions internal organs while insulating the body from heat loss.

Hard connective tissues, such as bones and cartilage, provide structure and support to the body. Other dense connective tissue types include the ligaments that bind and support bones in the joints, and tendons that attach muscles to bones. Both ligaments and tendons are essential for supporting and holding the bones together for smooth movements of the skeletal system.

Blood and lymph are fluid connective tissues involved in the body's homeostasis. They transport nutrients and remove wastes from the body. They also contain components of the immune system that protect the body from pathogens and participate in wound healing. Adipose tissue is a specialized connective tissue composed of cells with a large lipid droplet in the cytoplasm that doubles as an energy reserve.

Different types of connective tissues perform diverse functions like connecting, supporting, protecting, transporting, defending, and providing energy to the body.
