This unit explores multicellularity and how a system is higher than the sum of the parts. It begins with a sporting activities team an allegory to kick off this look at at cell specialization and at the ordered organization the cells into tissues, organs, organ systems, and also organisms. Students view the human being body together an exceptional cooperative neighborhood of trillions that cells the team approximately fight disease. Finally, students apply what they"ve learned about the body together a device to consider the system determinants that are thought about when matching organ donations come critically ok patients.
