The autonomic nervous system has two branches, sympathetic and parasympathetic. Activation of one branch typically suppresses activity of the other. If you eat a large meal, and then suddenly need to run, you will activate each system. Describe the likely chain of events that will transpire and include which system will take precedence.
What will be an ideal response?
Students often have personal experience with this, and know that the sympathetic system will predominate, so the meal will be regurgitated. They will usually explain that sympathetic activation will suppress parasympathetic, and that the body will also eliminate the meal from the system to allow the parasympathetic system to diminish while the sympathetic system is active.
