What is the main function of connective tissues?

The main function of connective tissues is to support other organs and structures within the body. Connective tissues serve as a framework that holds various parts of the body together, providing both structural support and stability. They consist of a variety of cell types and extracellular matrix that allow for the connection and anchoring of different tissues and organs. For instance, bone and cartilage are types of connective tissue that provide support and shape to the body, while adipose tissue (fat) plays a role in energy storage and insulation.

While other options relate to functions that can be associated with different tissues in the body, they do not encompass the primary role of connective tissue. Facilitating movement is mainly associated with muscle tissue, protecting against infection is the main role of the immune system (which involves specialized cells and tissues), and regulating body temperature is primarily managed by the integumentary system (skin) and associated mechanisms such as sweat glands and blood flow adjustments. Thus, the statement regarding connective tissue supporting other organs and structures accurately reflects its fundamental biological purpose.
