What role do osteoclasts perform in the skeletal system?
They form new bone
They break down bone cells
They repair fractures
They produce collagen fibers
The correct answer is: They break down bone cells
Osteoclasts play a crucial role in the maintenance of bone health by breaking down bone tissue. This process, known as bone resorption, is essential for maintaining the balance between bone formation and breakdown in the skeletal system. Through the action of osteoclasts, old or damaged bone is removed, allowing for new bone to be formed by other cells called osteoblasts. The activity of osteoclasts ensures that bones adapt to stress and repair themselves over time. This dynamic remodeling process allows the skeleton to maintain its strength and integrity throughout an individual's life. Thus, the function of osteoclasts is vital for bone homeostasis, ensuring that the skeletal system remains healthy and capable of supporting the body's needs.
