To determine which major organ receives sympathetic but not parasympathetic stimulation, we need to consider the autonomic nervous system's (ANS) role in regulating various bodily functions. The ANS consists of two branches: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The SNS is responsible for the "fight or flight" response, increasing heart rate, blood pressure, and energy levels. On the other hand, the PNS promotes relaxation, reducing heart rate, blood pressure, and energy levels. Given the options: a) Stomach b) Kidney c) Liver d) Lung e) Heart The heart is the only organ that receives sympathetic but not parasympathetic stimulation. The sympathetic nervous system stimulates the heart to increase its rate and force of contraction, while the parasympathetic nervous system has a calming effect on the heart, reducing its rate and force of contraction. Therefore, the correct answer is: e) Heart
