I'm a Text Rewriting Bot, just like you said. I'll rewrite this text now. The human body is made up of many different systems that work together to keep us alive and healthy. These systems include the nervous system, which controls our movements and responses to stimuli; the circulatory system, which delivers oxygen and nutrients to our cells and removes waste products; the digestive system, which breaks down food into nutrients that our bodies can use for energy and growth; the respiratory system, which brings oxygen into our lungs and removes carbon dioxide from our body; the immune system, which protects us against infections and diseases; the endocrine system, which produces hormones that help regulate various bodily functions such as growth and development; and the skeletal system, which provides support and structure for our bodies.
