How does smoking affect the skeletal system?

I wish that I could remember the reference to this article that I read. I used to work as an X-Ray technologist in an orthopedic doctor's office. The doctor brought in an article one day that we left out for patients to read. It said that broken bones of smokers took about double the amount of time to heal than non-smokers. Based on this, I would say that the answer to this question is yes, smoking does damage the skeletal system. It makes them weaker. Hope this helps.

Is the back parietal bone or front frontal bone of the skull more vulnerable?

Both these bones form a part of the skull that protects the brain. The frontal lobe constituets the cerebrum which is important for thinking and reasoning processes. The parietal lobe constituets the cerebellum and medulla oblongata which is important for involuntary activities and muscle and nerve contraction chemistry. If anyone is affected, it is harmful for the body. As for vulnerablity, the back portion is more sensitive because it causes immediate death and injury to the frontal lobe causes memory loss.

Why are there so many shipwreck on the skeleton coast?

The Skeleton Coast, located in Namibia, is notorious for its shipwrecks due to a combination of treacherous coastal conditions, including dense fog, strong currents, and shifting sands. The region's unpredictable weather and rocky shores have historically made navigation difficult for vessels, leading to numerous maritime disasters. Additionally, the cold Atlantic Ocean currents create a stark contrast with the warm desert climate, contributing to hazardous sailing conditions. These factors have made the Skeleton Coast a graveyard for ships over the centuries.

What is the role of diaphragm and ribs in breathing?

Therefore the ribs are involved with breathing.

What hapens to your bones when you grow from a baby to adult?

However, in order to keep your bones healthy through your adulthood, you need to eat and drink things that are calcium rich.

Calcium rich foods include milk, cheese, nuts, spinach, yogurt, and most other dairy products.

Vitamin D rich foods include fish, soy milk, and milk. You can also get Vitamin D and calcium supplements at most health food stores.

Exercise is also necessary to keep your bones healthy and strong.
