Physical Principles of Circulation

  • Y. C. Fung

Abstract

Blood flow must obey the principles of conservation of mass, momentum, and energy. Applied to any given region of space, the principle of conservation of mass means that whatever flows in must flow out. If flow is confined to blood vessels, then we obtain a rule similar to Kirchhoff’s law of electric circuits : At any junction the summation of current flowing into a junction must be equal to the sum of the currents flowing out of that junction. In a single tube of variable cross section, a steady flow implies that the local velocity is inversely proportional to the local cross-sectional area.
