y "w termta. 3. Increasing the temperature of the Ringer's solution bathing the frog heart will (decrease / increase / have no effect on) the heart rate of the frog. 4. Decreasing the temperature of the Ringer's solution bathing the frog heart will (decrease / increase / have no effect on) the heart rate of the frog. PhysioEx Ex. 6 – Activity 4 1. What effect would a parasympathetic agonist have on heart rate? 2. What effect would a parasympathetic antagonist have on heart rate? 3. What two effects would a sympathetic agonist have on heart rate? 4. What two effects would a sympathetic antagonist have on heart rate? 5. In this lab you applied several drugs to a frog heart. What drug might you administer if you need to increase cardiac output without affecting stroke volume*? 6. In this lab you applied several drugs to a frog heart. What drug might you administer if you need to decrease cardiac output without affecting stroke volume? 7. In this lab you applied several drugs to a frog heart. What drug might you administer if you need to increase cardiac output by increasing heart rate and stroke volume? * Note that increasing contractility increases stroke volume (because the heart pushes out more blood into the arteries if it contracts more forcefully.
