• The process of remodeling bone tissues involves bone cells resorbing or depositing minerals into bone tissue.
• During resorption, bone cells break down bone tissue and release calcium and other minerals for use by other cells in the body.
• Bone cells also rebuild bone tissue by depositing minerals obtained from the bloodstream.
• Bones are dynamic organs.
• Bone tissues engage in a continuous process of building, breaking down and rebuilding, depending on the body's need.
Bone processes - remodeling
Remodeling:
• Renews bone tissue before it deteriorates.
• Occurs at different rates throughout the skeleton.
• Begins early in development and continues throughout life.
Bone processes - response to stress in adult bones
• Bone remodeling redistributes bone tissue along lines of mechanical stress
• Under slight stress, bone tissues will be resorbed.
• Under heavy Stress, bone mass increases.
