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.
The blood transported by the circulatory system helps to regulate temperature because it holds heat. The specific heat of blood is high, and that helps it maintain a relatively constant temperature. If your body temperature is above normal, blood vessels near the body surface dilate to release excess heat.
