What is the role of the skeletal system?
Answer (1)
The skeletal system is the body’s framework, made up of 206 bones in adults, along with cartilage, ligaments, and joints. It provides structure, protection, and allows movement.Main functions:Support: The skeleton supports body structures and gives shape to the body. Without bones, we’d be a shapeless mass of muscles and organs.Protection: Bones protect vital organs:Skull → brainRib cage → heart and lungsVertebrae → spinal cordMovement: Bones act as levers, and joints allow for different types of motion. Muscles attach to bones and pull them during movement.Blood cell production: Red bone marrow inside certain bones produces red blood cells, white blood cells, and platelets through a process called hematopoiesis.Mineral storage: Bones store essential minerals like calcium and phosphorus and release them into the bloodstream as needed.Fat storage: Yellow bone marrow stores fats as energy reserves.The skeletal system is not just for movement—it also plays a key role in keeping internal systems functional and healthy.
