What is one function of the skeletal system?

The skeletal system has several crucial functions, one of which is the support and protection of internal organs. The bones form a rigid framework that maintains the shape of the body and supports its structure, allowing for the attachment of muscles and enabling movement. Additionally, many vital organs are safeguarded by the bones; for instance, the rib cage protects the heart and lungs, while the skull encases the brain. This protective aspect is fundamental to the overall survival of the organism as it helps to prevent injury to these essential systems.

While calcitonin is a hormone involved in regulating calcium levels in the body, its production is not a function of the skeletal system itself, but rather occurs in the thyroid gland. The production of blood cells, known as hematopoiesis, does occur within certain bone marrow cavities; however, this is just one of the many functions the skeletal system serves. Similarly, while the storage of minerals like calcium and phosphorus is a key role of bones, it is encompassed under the broader support and protection functions that the skeletal system provides.
