Which statement best describes the major functions of connective tissue?

• A. It forms the covering of body surfaces.
• B. It is primarily used for energy storage.
• C. It conducts electrical impulses to coordinate body activities.
• D. It stores calcium only in bones.

Answer: (C)

Connective tissue has a wide range of roles, including binding, supporting, protecting organs, and also storing energy and helping transport substances. Among the options, energy storage stands out because adipose tissue, a type of connective tissue, specializes in storing energy as fat and also provides insulation and cushioning. The other statements describe functions more typical of other tissues: covering body surfaces is a job of epithelial tissue; conducting electrical impulses is a function of nervous tissue; and while bone (a connective tissue) does store calcium, it isn’t the only place calcium is stored and calcium storage isn’t exclusive to bones.
