What is the hard tissue that forms the framework of the body?

1. Cartilage

2. Bone

3. Muscle

4. Connective Tissue

The correct answer is: Bone

Bone is the hard tissue that forms the framework of the body. It plays a crucial role in providing structure, protecting vital organs, facilitating movement by serving as levers for the muscles, and forming blood cells in the bone marrow. The dense and rigid quality of bone makes it essential for maintaining the shape and integrity of the skeleton, which is critical for overall body support. Other tissues listed have different functions: cartilage, while also a supportive tissue, is more flexible and found in areas such as joints and the rib cage; muscle is responsible for movement and contraction; and connective tissue has various roles, such as binding and supporting other tissues but does not form the hard framework. Understanding the distinct roles these tissues play highlights the unique importance of bone in the body's overall structure and function.
