Also know, how does the nervous system control the heart rate?
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.
Furthermore, when you are in danger which part of the nervous system is responsible for your heart rate increasing? The sympathetic nervous system responds to impending danger or stress, and is responsible for the increase of one's heartbeat and blood pressure, among other physiological changes, along with the sense of excitement one feels due to the increase of adrenaline in the system.
Then, which part of the nervous system controls the respiratory rate heart rate and blood pressure?
It connects the higher parts of the brain to the spinal cord (see the picture at the right of this page). The cardiac, respiratory, and vasomotor control centers are in the medulla. This means that the medulla controls heart rate, blood pressure, breathing, and the size of the body's blood vessels.
What nerve tells you to breathe?
The vagus nerve is basically listening to the way we breathe, and it sends the brain and the heart whatever message our breath indicates.
