WebHowever students are exposed to hemodynamics— whether by lecture or by directed reading and self-study—they must come to understand these basic variables and how they interact. Be sure to identify the units of each variable, as it is introduced, and insist that the students use appropriate units in their an-swers and questions. WebThe study of hemodynamics integrates a number of sciences, including biology, chemistry, and physics. As the heart pumps blood through the blood vessels, it helps to supply oxygen to the organs and tissues of the body. This process is vitally important so that the body can maintain itself.
