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.
When the body temperature rises, the sympathetic nervous system stimulates the eccrine sweat glands to secrete water to the skin surface, where it cools the body by evaporation. Thus, eccrine sweat is an important mechanism for temperature control.
