Circulation (Lesson #1: Blood)

Overview

The series begins by looking at diseases affecting the circulatory system, a major cause of death in the UK. Von Hagens and Lee explain that rather than life hanging by a thread, it hangs by a tube. In particular they demonstrate the complex network of blood vessels that deliver oxygen to our vital organs. If some of these narrow, harden, become blocked or burst, they can damage the heart and end in what we understand as a heart attack.
