the main function of the muscular system is movement, but it also helps stabilize our joints, maintain our posture and generate heat during activity. And then our skeletal system is made from Bone. In the areas of the skeleton where bones move (for example, the ribcage and joints), cartilage, a semi-rigid form of connective tissue, provides flexibility and smooth surfaces for movement. The skeletal system is the body system composed of bones and cartilage and performs the following critical functions for the human body:
supports the body
facilitates movement
protects internal organs
produces blood cells
stores and releases minerals and fat in order for it to do these functions you need to contract the muscles in your body to help your skeletal structure.
