2. Four

3. Six

4. Three

The correct answer is: Six

The skeletal system is comprised of three main components: bones, cartilage, and ligaments. These components play critical roles in providing structure, support, and protection to the body. Bones are the rigid organs that make up the skeleton, serving as a framework for the body and facilitating movement by acting as levers for muscles. They store minerals, such as calcium and phosphorus, and contain bone marrow, which is vital for producing blood cells. Cartilage is a flexible connective tissue that provides cushioning at joints, reduces friction between bones, and supports various structures, such as the ears and nose. It plays an essential role in the growth and development of bones, especially during childhood and adolescence. Ligaments are strong connective tissues that connect bones to other bones at joints, helping to stabilize and support the skeletal system while allowing for a range of movements. Together, these three components work in harmony to maintain the body's integrity and functionality. Understanding these components is crucial for anyone studying first aid or any other medical field, as they relate to common injuries and treatments involving the skeletal system.
