Answer:
The heart pumps blood into different areas of the body. So it is helping everything in your body. The heart also pumps blood for you to think so the control of the heart helps you live.
Step-by-step explanation:
Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The sympathetic nervous system (SNS) releases the hormones (catecholamines - epinephrine and norepinephrine) to accelerate the heart rate.
