What our heart tends to beat faster when you are excited, for eg going to see your lover in short while?

Answer 1

I'm sorry but what's the question?

Answer 2

You are not going like this answer...it is hardly romantic.

Heart rate is controlled by several factors but the main stimuli is the parasympathetic and sympathetic fibres of the autonomic nerve system. The parasympathetic fibres (particularly from the right chain) have a inhibitory effect on the heart rate. The heart’s inherent firing rate determined by the pacemaker cells of the SA node is about 80-100 beats per minute. But due to the vagus nerve having a tonic breaking effect on the cardiac muscle cells acting via acetylcholine receptors, the resting heart rate is below that of the inherent level – 60-80 beats per minute. Increased vagal influence, beyond that of normal levels will cause bradycardia.

Heart rate can also be controlled by the sympathetic division of the autonomic nervous system and this is by the cardiac accelerator nerves. These nerve act via Beta 1 noradrenergic receptors to reduce the threshold potential of the muscle fibres and therefore allowiing for threshold to be reached more readily. This causes a greater level of heart rate. Increased levels of cardiac accelerator nerve activity will cause tachycardia.

Hey...you asked, heh, heh.

Seeing your lover, kissing your lover, etc is exciting and as such your body responds by excreting adreniline into the blood stream, which causes you to breath harder and your heart to beat harder.

Have fun.

Answer 3

Its a response to stress. When we know we are about to do something thats going to excite us for either good or bad reasons, the heart prepares the body for the event, just incase you have to do something highly physical. In your case, its probably for making some of that sweet sweet tender love'n.

Answer 4

Did you mean "why"? I'd say it's adrenaline.
