Regulating Body Temperature - Homeostasis

In order to maintain the body temperature the body...

  • contains sweat glands
  • network of capillaries just under the surface

If the core temperature is too high

  • blood vessels dilate (get wider)
    • more blood flows through the capillaries & more heat loss from skin
  • Sweat glands sweat more
    • cools the body as it evaporates

If the core body temperature is too low, then:

  • blood vessels constrict (get narrower)
    • reduces flow of blood through capillaries & reduces heat loss
  • shivering muscles
    • contraction needs respiration, which releases some energy as heat

Homeostasis is when the body's internal environment is kept constant.

Since amino acids cannot be stored in the body the excess amino acids:

  • Are first broken down...
  • It is then made into urea in the liver...
  • After which the kidneys filter urea out of the blood...
  • and then it forms urine and is stored in bladder!
