Which primary tissue type binds, supports, and protects the body's tissues and organs?

• A. Epithelial
• B. Nervous
• C. Muscle
• D. Connective

Answer: (D)

Connective tissue is defined byIts role in binding tissues together, providing structural support, and protecting organs. The tissue type achieves this through an abundant extracellular matrix that surrounds widely spaced cells, giving it the strength and resilience to hold the body together and cushion or shield internal structures. Examples like bone and cartilage provide rigid support, tendons and ligaments bind organs to each other and to bones, adipose stores energy and cushions, and blood transports nutrients and wastes while supporting immune defense. By contrast, epithelial tissue mainly lines surfaces and forms barriers; nervous tissue specializes in transmitting signals; muscle tissue contracts to produce movement. Because binding, supporting, and protecting tissues and organs is the core function of connective tissue, it is the best answer.
