Biology
1. Functions of the Skeletal System Support: The skeleton provides a rigid framework that supports the body’s structure and maintains its shape. Protection: Bones encase and protect vital organs (e.g., the skull protects the brain, and the rib cage shields the heart and lungs). Movement: Bones act as levers that muscles pull on to produce movement. Joints between bones facilitate various types of movement. Mineral Storage: Bones store essential minerals, particularly calcium and phosphorus, which can be released into the bloodstream as needed. Blood Cell Production: The bone marrow, found within certain bones, is responsible for producing red blood cells, white blood cells, and platelets in a process called hematopoiesis. Energy Storage: The bone marrow also stores lipids in adipocytes (fat cells), which serve as an energy reserve. 2. Types of Bones Long Bones: Longer than they are wide (e.g., femur, humerus). They are crucial for movement and leverage. Short Bones: Appro...
