The nervous system
your heartbeat will slow
The sympathetic nerves speed up the heart rate, while the parasympathetic nerves slow it down.
There are a great number of chemicals that can speed up or slow down the heart rate, as well as chemicals that can change the rhythm of your heart.
No foods will significantly reduce your heart rate. Caffeine may speed it up, but nothing will slow it down.
The parasympathetic nervous system helps regulate heart rate by slowing it down. It works in opposition to the sympathetic nervous system, which speeds up heart rate.
You can maintain your desired heart rate by wearing a heart rate monitor. These are small electronic devices that usually resemble a wrist watch. The heart rate monitor will display your current heart rate and allow you the opportunity to either speed up or slow down your running pace in order to stay within what your desired heart rate is. If you notice your heart rate is getting higher than desired, slow down, and if it is lower than desired, speed up.
No, the parasympathetic n.s. will slow the heart down, the sympathetic n.s. will increase heart rate.
Yes, but not somatic nerves. Instead the heart is enervated by the autonomic nervous system (used mainly to speed up and/or slow down the heart rate). There is also an internal set of nerves (referred to as Perkingi fibers) that are used to synchronize the beats of the heart.
The parasympathetic division of the autonomic nervous system is responsible for decreasing heart rate. It releases acetylcholine to slow down the heart's activity.
alcohol makes you very clumsy and slow and is a depressant, unlike ecstacy, it will slow down your heart rate.
The pulse is a measure of the heart rate.
Caffine will speed up the heart rate.
