temperature and is responsible for for controlling the mechanisms that will decrease the blood temperature. Efferent nerve impulses are sent from the hypothalamus to multiple different corrective mechanisms to try to decrease the blood temperature and maintain it at approximately 37℃. The efferent nerve impulses causes the smooth muscles to relax and as a result‚ opens up blood capillaries near the surface of the skin.

A normal heart rate is expressed as the amount of times it beats in a minute; a normal adult heart rate is between 60-100 beats per minute (BPM). There is a relation between these two measurements‚ but they are stimulated by several different circumstances. The blood pressure is mainly affected
