The skeleton is the body part that forms the supporting structure of an organism. It can also be seen as the bony frame work of the body which provides support, shape and protection to the soft tissues and delicate organs in animals
FUNCTIONS OF THE SKELETAL SYSTEM
Skeletal system has several additional functions, including:
- Protecting internal organs from injury. For example, the skull protects the brain, while the thoracic cage protects the heart and lungs.
- Allowing for movement. Muscles attach to bones through tendons. This connection allows the body to move in many different ways.
- Producing blood cells. The soft bone marrow inside of many bones produces red blood cells, white blood cells, and platelets.
- Storing minerals and nutrients. Bones can store and release minerals, including calcium and phosphorus, which are important for many bodily functions. Additionally, adipose (fat) tissue that can be used as energy can be found in part of the bone marrow..
