How the human body works

The human body is an amazing interconnected system of systems. Many types of organs work together to perform a specific function, and the organ systems function together to give us life and health. Although studied and treated individually, the organ systems operate as a team in human biology; some are more essential to life than others, but all are fascinating and complex. This course discusses various human biological systems and how each functions to keep you alive.
