Two major control centers for homeostasis are:
Correct answer: D. Brain and endocrine glands
- A. Exocrine and endocrine glands
- B. Apocrine and Heterocrine glands
- C. Receptors and effectors
- D. Brain and endocrine glands
Explanation
The body temperature regulation in humans is based on complex homeostatic systems facilitated by feedback mechanisms. The homeostatic thermostat is present in the hypothalamus, a brain part. It responds to the changes in the temperature above and below a set point, which is 37 °C. In case of increase in temperature above the set point, certain warm temperature sensitive thermoreceptors in skin, hypothalamus and other parts of nervous systems send the signals to the system that increase the blood low to the skin and also cause sweat gland activation and the sweat is evaporated for the cooling.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
