ELEKTRIC MODEL OF AORTAL FUNCTION

I. Schematically redraw modeled records and describe the changes

BP,

mmHg
Changes in stroke volume


    SV=50ml

           SV=90m

SBP



DBP

Time, s
PP=pulse pressure, MABP=mean arterial blood pressure

BP,

mmHg
 Change in peripheral resistance


    R = 0,5–0,8 mmHg^.s/ml

                          R = 1,2–1,5 mmHg^.s/ml

II. Interest tasks:

BP,

mmHg
Model and describe the changes in blood pressure during the stay in the sauna followed by a cool
down (the heat reduces peripheral resistance, the cold increases peripheral resistance).

Time, s







Model and describe the changes in blood pressure during physical activity (gradual increase of
systolic output and heart rate, and then reduction of peripheral resistance).

BP,

mmHg

Time, s








BP,

mmHg
Model and describe essential hypertension (increased SV and TF by + 20%) and fully developed
hypertension (return of TF and SV to the original values and increased resistance by 40%).

 Conclusion


BLOOD FLOW IN VEINS

Draw a diagram of veins and valves. Draw the course of the veins on the volar side of the forearm
and mark the location of the flaps of your experiment.
