It regulates temperature, glucose, toxins, blood pressure, and pH.

TemperatureThe body must maintain a relatively constant temperature. If it gets too hot, the body employs vasodilation to cool down. This dilates the blood vessels, allowing more heat to escape from them through the skin.
GlucoseThe body must regulate glucose levels to stay healthy. When glucose levels become too high, the body releases a hormone called insulin. When they become too low, the body converts the glycogen in the blood to glucose.
ToxinsToxins in the blood can disrupt the body's homeostasis. Thus, it signals the urinary system to ensure that the toxins are excreted.
Blood PressureThe body must maintain healthy levels of blood pressure. To do so, the brain sends signals to the heart to speed up or slow down according to the blood pressure.
pHThe lungs control the pH amount in the body. If pH levels become unbalanced, the lungs push more or less carbon dioxide out of the diaphragm. This can raise or lower pH levels in the body.</span>

<span>Motor
neurons tend to function less as age sets-in in a particular individual.
Reaction time is the ability to respond quickly to stimulus presented in a
given situation. An example of this is the gun start that is commonly used in
athletic competitions where a person reacts quickly to the signal and performs
the activity. As we age, our
sensory systems deteriorate and as a result some of the skills we have when we were
younger are not as effective as it was when we turned into mature adults. </span></span></span>
