The human body is a complex machine that is made up of millions of tiny parts working together to keep us alive and functioning properly. The heart beats continuously pumping blood through our veins and arteries, supplying oxygen and nutrients to all the cells in our body. The brain is like a supercomputer controlling everything from our movements and actions to our thoughts and emotions. It sends signals through the nervous system telling our muscles what to do and when to do it.
