How the body works

All of us have one, but the corpus humanum is much more than just a fleshy vessel for our brains. The human body as we know it today is the result of millions of years of evolution and is composed of trillions of cells each working to keep our biological systems ticking along. Whether they're regulating our body temperature or maintaining the correct oxygen levels in our bloodstreams, the organs that make up our bodies are undoubtedly essential in helping them work.
