Question

Quizplus · Accepted Answer

The heart is innervated by both the sympathetic and parasympathetic branches of the autonomic nervous system. The sympathetic nervous system can increase heart rate to meet the body's demands, such as during exercise, while the parasympathetic nervous system can decrease heart rate during restful periods. This dual innervation allows for precise control of heart rate based on the body's needs.
