Human Body Systems (HBS) is the second course in the Project Lead the Way Biomedical Science program. HBS builds on the foundation laid down in Principles of Biomedical Science (PBS). Students examine the interactions of human body systems as they explore identity, power, movement, protection and homeostasis. Exploring science in action, students build organs and tissues on a skeletal Maniken® model; use data acquisition software to monitor body functions such as muscle movement, reflex and voluntary action, and respiration; and take on the roles of biomedical professionals to solve real-world medical cases.
