Frontiers of Biomedical Engineering (BENG 100) Professor Saltzman discusses the biophysics of the circulatory system. It begins by describing the anatomy of the different types of blood vessels, and notes the relationship between pressure difference (AP) as the driving force for the flow (Q) in a tube (blood vessel for example) with some resistance R (AP = RQ). R is calculated when the dimensions of the tubes (L, R) and viscosity (μ) are known: R = 8μL/πr4. Subsequently, the traces Professor Saltzmanthe flow of blood through the circulatory system and explains how the body can regulate the flow of blood to certain areas of the body. Finally, he describes the heart and its function as a generator of pressure in the system. 00:00 - 03:46 Introduction Chapter 1 - Chapter 2 15:42 The heart in the blood - Chapter 3 Blood flow and pressure 45:03 - Chapter 4 The flow of blood within the closed circuit of the complete course materials are available on the Open Yale Courses Web site:open.yale.edu This course has been launched in the spring of 2008.
