The body is made up of a number of systems that all interlink and produce everything we need in order to survive. Within the body there is the digestive system; the circulatory system‚ the nervous system‚ the muscular system‚ the skeletal system and the reproductive system. These systems are all part of one another and they share organs‚ tissues and cells and that is how they interlink. The diagram above shows each system and where they are located in the body. Each system is shown in a different
