The Valves in your Heart and Veins are One Way Streets. But don't take my word for it. Talk to the bioengineering students who are taking this message to the nation's capital this weekend. It's part of the USA Science & Engineering Festival.
Read all about the project on the heart valve story on the Jacobs School Web site.
Watch a preliminary video of the UCSD bioengineering students in the process of creating their make-your-own-blood-valves activity for kids.
A few photos are below, and stay tuned for photos and updates from the students at the event over the weekend.
