Which of the following are true about the interactions between or among integumentary, muscular and skeletal systems of the human body

The interactions between the integumentary, muscular and skeletal systems of the human body are designed to work together to allow the human body to function optimally. They are different systems but work together. The integumentary system is the human body's skin. Its function is to cover the muscular and skeletal system. It also prevents bacteria from attaching itself to the muscular system.The skeletal system is our bone structure. The bones in the human body keep us upright. The muscular system is what attaches the bones to each other and allow us to move.
