What are the Major Functions of the Skeletal System in the Human Body?
The skeletal system is a complex and vital part of the human body, serving numerous essential functions. Its primary roles can be summarized as follows:
1. Support and Framework: The skeletal system provides the body with a rigid framework that supports and protects vital organs, muscles, and other tissues. It allows for upright posture and supports body movements.
2. Protection: The skeletal system, especially the bones of the skull, ribs, and pelvis, forms a protective cage that shields the brain, heart, lungs, and reproductive organs from external impacts and injuries.
3. Mineral Storage: Bones store and release minerals, primarily calcium and phosphorus. These minerals are essential for various bodily functions, including bone strength, muscle contraction, and nerve transmission.
4. Movement: The skeletal system, together with the muscular system, facilitates coordinated movements. Muscles attach to bones and contract, causing joints to move and generate body movements.
5. Blood Cell Production: Bone marrow, located within the cavities of certain bones, is responsible for producing red blood cells, white blood cells, and platelets, which are essential for oxygen transport, immune defense, and blood clotting.
