3. The layer of the blood vessel that is stimulated by the autonomic nervous system is 4. In the experiment, the pump simulates 5. If the right beaker simulates the flow of blood to the systemic circuit of the body, what do the right valve and flow tuberepresent? 02/25/19 page 1
02/25/19 page 2 Experiment Results Predict Question: Predict Question: If you increase the flow tube radius, what will happen to the pump rate to maintain constant pressure? Your answer : b. The pump rate will decrease. Stop & Think Questions:When the piston of the pump reaches its lowest point, the volume remaining in the pump is the If you increase the right flow tube radius, what will happen to resistance and flow rate? If the left flow tube represents the pulmonary veins, what does the left source beaker represent? Experiment Data: Flow (ml/min) Rad. L (mm) Rad. R (mm) Str. V (ml) Rate (strokes/min) Press.

02/25/19 page 3 Post-lab Quiz Results You scored 100% by answering 5 out of 5 questions correctly. 1. The pump piston in the simulation is up during 2. The pump in the simulation represents the 3. The amount of blood flowing into the destination beaker (right beaker) with a single pump is called the 4. In this experiment, the increase in right flow tube radius resulted in 5. Which chamber should be present in the flow pattern of the experiment, given that the vessels and valves surrounding itare present (the chamber was omitted from the experiment for simplicity)?
02/25/19 page 4 Review Sheet Results 1. Explain the effect of increasing the right flow tube radius on the flow rate, resistance, and pump rate.
