What are two mechanisms that can increase End Diastolic Volume (3 given in lab) 15. In this experiment they were showing that the pump rate changed when the Stroke Volume changed in order to maintain a constant blood flow. Fill in the data chart below using the values recorded. Fill in the data chart below. At a constant pressure of 100mmHg Stroke Volume in ml Pump Rate 10 20 30 40 50 60 80 100 I felt they graphed the wrong thing. Please graph on the graph below the pump rate vs. the stroke volume on the graph on the next page. Which is the dependent variable? Don't forget to label your axes. What does this graph say about how decreasing the heart rate can increase stroke volume? Why is it possible for the heart to increase stoke volume when the End Diastolic Volume increases? And whose Law is this? Flow (ml/min) Str. V (ml) Rad. L (mm) Rad. R. (mm) Rate (strokes /min) Press. L (mm Hg) Press. Dif.
