Question 24

What happens when you exercise to your bones

Answer 24

When you exercise you cause microscopic damage to your bones.
Organisms called osteoclasts remove any unnecessary calcium phosphate from the damaged area.
the osteoblasts then bring new calcium to the area which helps create new bone.
Osteoblast activity increases after exercise, therefore the more you exercise the stronger your bones become.
