What is the primary function of the skeleton in the body?

The primary function of the skeleton in the body is to provide protection for vital organs. The skeletal system forms a rigid framework that not only supports the body's structure but also safeguards essential organs such as the heart, lungs, and brain. For instance, the rib cage encases and shields the heart and lungs from physical impact, while the skull protects the brain. Additionally, the skeleton provides attachment points for muscles, allowing for movement and maintaining posture, but the protective role is a fundamental aspect of its purpose, ensuring that critical components of the body are well-guarded against potential injuries.

The other options pertain to functions that the skeleton does not serve. While digestion and nutrient absorption are vital bodily functions, they are primarily the responsibilities of the digestive system. Similarly, hormone production is primarily managed by glands in the endocrine system, not directly by the skeleton itself.
