Which of the following correctly describes the thermoregulation in hot temperature?
Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
In hot temperatures, the body needs to cool down, which is done by increased blood flow to the skin, so that more heat is released from the blood as well as sweat production is increased, so that when the sweat evaporates it cools down the body, hence option A and C is incorrect. The blood flow is increased by dilating the vessels which increases their diameter hence allowing more blood to flow, so options A and B are incorrect. The option with the correct combination is option D.

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.
