Based on the teaching practice,this paper discussed nine topics in fluid dynamics:scientific research methods,theoretical foundation of hemodynamics and hemorheology,physical meaning of Bernoulli's equation,physical meaning of Newton viscosity law,Poiseuille principle on flow blood,mathematical description of volume flow,concept of velocity gradient,physical meaning of Reynolds number,and flow resistance.By combining preparing lessons and teaching practice,this paper comments on these nine topics and point out several inaccurate descriptions in some textbook.As a reference,it could benefit for teachers and students.
