This video segment from Design Squad features the work of Howard Pryor, a tissue engineer and doctor at Massachusetts General Hospital. Dr. Pryor demonstrates a device he is working on to replace diseased livers. He explains the challenges of artificially engineering a human organ, including getting blood to flow through a device for processing just as it would through a liver. He also details the design process. This resource is useful for introducing components of Engineering Design (ETS) from the Next Generation Science Standards (NGSS) to grade 9-12 students.
