Score is an old word for the number 20. = (4*20+7)years = 87 years. And in the Bible: âthree score years and tenâ meaning: âseventy years oldâ (3*20+10) (Psalm 90). This was thought to be a normal life span.
One of the functions of the Integumentary System is the negative feedback, homeostatic control of the core body temperature. This is called thermoregulation.
If body temperature is below the set point, muscles shiver to generate heat and the constriction of the blood vessels helps the body retain heat. This example is very complex because the hypothalamus can change the body's temperature set point, such as raising it during a fever to help fight an infection.
