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 integumentary system (the skin) is involved in protecting the body from invading microbes (mainly by forming a thick impenetrable layer), regulating body temperature through sweating and vasodilation/vasoconstriction, or shivering and piloerection (goose bumps), and regulating ion balances in the blood.
