Smoking reduces the flow of blood to the bones, which slows down bone remodeling and therefore makes your bones weaker.
definition
A good blood supply is essential for proper remodeling of the bones. To be healthy, bones, like any other living tissue, need the oxygen and nutrients that blood supplies.
Perfusion means the movement of blood throughout a tissue. When the body's tissues are not well perfused blood, they will not function properly or may even die.
explanation
Some people are surprised to learn that smoking can affect their bones. After all, the bones seem hard and strong, like rocks. It's hard to imagine that they could be damaged by anything less than a serious accident or bad fall.
Actually, though, bones aren't solid like rocks. They are living, changing tissues, just like all of the other parts of your body. Every day, some of the tissue in your bones is broken down, and new bone is made to replace it. This process, which is called remodeling, takes place throughout your life.
