Chapter 49. Blood Pressure and Heart Rate Simulation

Four additional conditions listed in the simulation can be added to one or the other columns in this table. Think about how each of these conditions would affect mean arterial pressure (MAP) and then map each one to one of the columns in the table. Use the simulation to test your prediction before committing to one of the four options below.

Use the simulation to compare the actions of the parasympathetic and sympathetic nervous systems in each of the conditions. What relationship do you find?

Which condition would you expect to result in these changes? Use the simulation to test your prediction before committing to one of the four options below.

Which two physiological changes could each independently have this type of effect on heart rate and stroke volume? Use the simulation to test your prediction before committing to one of the four options below. Remember that blood vessels dilate during anaphylactic shock and that reduced ventricular function occurs during myocardial infarction.
