  1. Skeletal & Muscular System

  2. Skeletal System

  3. Function: • The skeletal system …. • Holds the body up (structure and shape) • Protects internal organs • Helps the body move • Stores minerals, Calcium, Phosphorus • Makes blood cells

  4. PARTS-BONES • -make up the skeletal system • Made of living cells and protein fibers • - Produce blood cells in the bone marrow • - 206 bones in adult body • - 300 bones in infant (later fuse together)

  5. PARTS-CARTILAGE • - gives shape • Connects the bones • Supports the body • Softer and more flexible than bone

  6. PARTS-LIGAMENTS • holds bones together at the joins • Connects bone to bone • 900 ligaments in human body

  7. PARTS-JOINTS • place where 2 or more bones connect together • Allow movement

  8. PARTS-TENDONS • tough connective tissue that • connects bone to muscle http://science.howstuffworks.com/life/6830-human-body-bone-strength-video.htm

  9. MUSCULAR SYSTEM

  10. Function The muscular system… -helps you move -helps move blood through the body (arteries/veins/capillaries) -pumps your blood (heart) -helps you breathe (lungs) -moves food through digestive system (stomach, intestines)

  11. TYPES OF MUSCLE • SMOOTH MUSCLE • tissue in walls of organs, arteries, veins • In the stomach, lungs, and other soft internal organs • Involuntary movement (moves by itself) • Controls the way blood flows through circulatory system

  12. TYPES OF MUSCLE • SKELETAL OR STRAITED MUSCLE: • attached to legs, arms, back, and torso • Helps to move bones • Voluntary movement

  13. TYPES OF MUSCLE • CARDIAC MUSCLE: • - only in the heart • involuntary movement (moves by itself)

  14. CONNECTION TO OTHER SYSTEMS • Skeletal and muscular system work together to help you move • Muscular system works with circulatory system to pump blood through the body • Muscular system works with digestive system to move food through digestion • Muscular system works with respiratory system to exchange gases • Muscular system works with excretory system to eliminate waste • Nervous system controls skeletal and muscular system
