Living Physics Portal: Modeling Flow through the Resistance Vessels

Abstract: Section 4 of the Physics of the Cardiovascular System investigates resistance factors in the smaller blood vessels. Students will: 1) analyze pressure drops that occur with position along the circulation cycle for a supine patient in the small resistance vessels; 2) use a physical model to investigate the resistance vessels of the circulatory system; and 3) apply the Hagen-Poiseuille Principle for resistance vessels and the parallel nature of the small branches of the circulatory system to an understanding of blood flow in health and disease.
