Document Summary
Structure and support: structural support for organs and body segments, protection of the brain and internal organs, muscle support for movement. Metabolic processes: mineral storage, production of blood cells in bone marrow. Most prevalent bone disease in n. america. Bone is weakened: low bone mass & deterioration of bone tissue. What happens when bones fracture: osteoporosis causes: Childhood and adolescence are particularly important periods. Low intakes of calcium, vitamin d and other bone nutrients. Your bones only grow in size and density during childhood and adolescence. You reach your peak bone mass between 20-30 years of age. Your bone mass declines after the age of 50. Your body constantly breaks down and builds up your bones to keep them strong. As you grow, osteoblast work faster - you gain bone, as you age, osteoclasts work faster. Peak bone mass: having a high peak bone mass protects you from osteoporosis.
