A. Producing hormones
B. Transporting oxygen
C. Protecting organs and supporting the body
D. Digesting food
Answer (1)
The correct answer is C. Protecting organs and supporting the body The skeletal system serves several vital roles, but its main function is to support the body’s structure and protect internal organs. It provides the rigid framework that allows the body to maintain its shape, posture, and ability to move with the help of the muscular system.There are more than 200 bones in the human body, each with a specific function. Some of these functions include:Protection - The skull protects the brain, the rib cage protects the heart and lungs, and the vertebrae protect the spinal cord.Support - Bones act like the beams and pillars of a building. Without bones, our bodies would collapse like a jellyfish.Movement - Bones provide attachment points for skeletal muscles, allowing us to move when muscles contract and pull on bones.Mineral storage - Bones store essential minerals like calcium and phosphorus, which can be released into the bloodstream when needed.Blood cell production - Within bones is the bone marrow, where red blood cells, white blood cells, and platelets are produced in a process called hematopoiesis.The skeletal system is divided into two main parts:The axial skeleton (skull, spine, rib cage)The appendicular skeleton (limbs, pelvis, shoulders)Diseases of the skeletal system like osteoporosis weaken bones, increasing the risk of fractures. Learning about this system also helps students understand posture, growth, bone injuries, and proper nutrition for bone health (like calcium and vitamin D intake).
