It does not need our thoughts to move. The heart continues to beat even if you are sleeping or unconsious. There is a special section of the brain that regulates heart rate.
An Artificial Pacemaker basically regulates the rate of the heart beat depending on the needs of the body.
The subdivision of the peripheral nervous system (PNS) that regulates the activity of the heart is the autonomic nervous system (ANS). Specifically, the sympathetic division increases heart rate and contractility, while the parasympathetic division, primarily through the vagus nerve, decreases heart rate. Together, these divisions help maintain homeostasis in cardiac function.
The medulla oblongata, located in the brainstem, controls breathing, heart rate, and respiration. It regulates these vital functions automatically without conscious effort.
Drinking cold water can have a temporary effect on the heart rate, causing it to temporarily increase. This is because cold water can stimulate the vagus nerve, which regulates the heart rate. However, this effect is typically short-lived and not harmful for a healthy heart.
The thyroid gland, located in the neck, regulates metabolism by producing hormones that control the rate at which the body uses energy. These hormones also help in regulating various bodily functions such as heart rate, digestion, and brain development.
