Why is bone considered an organ?

Bones usually refer to the skeletal system. The skeleton is considered an organ because it possesses the characteristics of an organ, as analyzed below:

The skeleton is a relatively hard, honeycomb-like three-dimensional structure within the human body, containing bone marrow, periosteum, nerves, blood vessels, cartilage, and other components. It serves to protect internal organs, maintain body posture, produce blood cells, and store essential minerals. In addition, in coordination with skeletal muscles, tendons, ligaments, and other tissues, bones generate and transmit forces that enable body movement. In clinical terms, an organ is defined as a unified structure composed of various complex tissues that work together to perform specific functions. Given these features, the skeleton meets the criteria and is therefore classified as an organ.

In daily life, if abnormalities occur in the bones, it is important to promptly seek proper medical treatment at a hospital's orthopedic department to improve the condition and promote rapid recovery.
