📖 Description
Whether you are taking a nap, running a marathon, or eating a gourmet dinner, your body is working hard to make sure everything is running smoothly. The body consists of 11 different systems, and each one is made up of cells, tissues, and organs. Although each system has a specific job, multiple systems work together to perform more complex tasks. From breathing to digestion, your body systems carry out all the functions necessary to keep you healthy.
