Cardiovascular System

Product ID:  PIM/D1019            99.95

The Cardiovascular System dynamically presents topics which relate to heart and blood vessel physiology.

       Heart Physiology:

        Anatomy Review: The Heart
             By illustrating the external and internal heart from four different
          views, students are provided with greater  understanding of the
          spatial relationships among heart structures. The overall circulation
          in the body is animated, and cardiac muscle cell anatomy is
          illustrated with a surprise visit from our virtual professor,  Elaine
          Marieb.

        Intrinsic Conduction System
             An animation shows the pathway of depolarization inthe heart, and
          ECG waves are explained. The two are then put together to help
          students understand the correlation between an ECG graph and
          events in the  heart. The quiz includes matching and puzzle
          exercises,  and then students must apply their knowledge to two
          clinical situations—a left bundle branch block and tachycardia.

       Cardiac Action Potential
           Using animations, students are led step by step throughthe difficult
         concepts of pacemaker potentials and action potentials. Animated
         events in autorhythmic and contractile cardiac cells are correlated
         with animated graphs of membrane potential. The quiz questions
         require students to demonstrate their understanding of membrane
         potential and the roles of various ion channels.

       Cardiac Cycle
          An animation of blood flow through the heart is presented, followed
         by step-by-step animations and explanations of the phases of the
         cardiac  cycle.  The blood flow animation is then correlated with
         animated graphs of pressure, ventricular volume, and an ECG. This
         allows students to make the connections between the graphs and
         events occurring in the heart. The quiz tests student understanding
         of the stages of  the cardiac cycle in relation to heart valves, blood
         flow, and the ECG/pressure/volume graphs.

       Cardiac Output
           Cardiac output is demonstrated in a way that could only be done
         on computer! Students are also asked to predict the effects of 10
         different factors on heart rate, stroke volume, and cardiac output, 
         and then given an explanation for each factor. In the quiz, students   
         must calculate cardiac output and relate it to the volume of soda
         bottles, and demonstrate their understanding of heart rate and
         stroke volume regulation. 

Blood Vessel Physiology:

      Anatomy Review: Blood Vessel Structure and Function
        The flow of blood is traced through the blood vessels of the body, 
        using animations to demonstrate the structural and functional 
        characteristics of each vessel type.

      Measuring Blood Pressure
        This topic illustrates what is happening in the bodyhen blood pressure 
        is measured. The quiz gives students an opportunity to try their hand
        at interpreting blood pressure measurement sounds.

      Factors That Affect Blood Pressure
        Animations and analogies are used to demonstrate the factors that
        affect blood pressure. In the quiz, students must identify the factors
        that will lower someone’s blood pressure.

      Blood Pressure Regulation
         Using animations, students are helped to understand the complexities
         of short-term and long-term regulation of blood pressure. In the quiz,
         students can experiment with the effects of nerve stimulation,
         epinephrine, and acetylcholine. Also, they must correctly identify
         the chain of events that begins when dehydration occurs, and when
         blood volume and blood pressure are increased or decreased.

       Autoregulation and Capillary Dynamics
         Animations and analogies are used to explain the  control of blood
         flow through individual organs (autoregulartion) and the movement
         of solutes and fluids across capillary walls. In the quiz, students must
         apply their knowledge of autoregulation to muscle cells.  Also, they
         must use their understanding of capillary dynamics to predict how
         digested foods and respiratory gases are transported across capillary
         walls.
