   2. excretion
   3. absorption
   4. circulation

   2. urinary system
   3. cardiovascular system
   4. respiratory system
   
   
5. According to the principle of homeostasis, a controlled factor such as internal body temperature
   1. never rises above the normal value known as the "set point"
   2. never falls below the normal value known as the "set point"
   3. fluctuates slightly above and below the normal value known as the "set point"
   4. is not regulated until it goes outside the normal range
   
   
6. Which one of the following statements is false?
   1. Body heat is produced mainly by absorption of energy through the skin.
   2. Skin contains numerous vessels that are capable of dilation and constriction.
   3. If heat production is greater than heat loss, body temperature goes up.
   4. If heat production is less than heat loss, body temperature goes down.
   
   
7. If body temperature is decreasing and about to fall out of the normal range, responses will occur to raise the body temperature. This response would be considered
   1. positive feedback, because the effect is to raise the temperature
   2. negative feedback, because the process results in a reversal of the condition that triggered it
   
   
8. Dilation of blood vessels in the skin
   1. causes more blood to flow into the skin and would be likely to raise body temperature
   2. causes more blood to flow into the skin and would be likely to lower body temperature
   3. causes less blood to flow into the skin and would be likely to raise body temperature
   4. causes less blood to flow into the skin and would be likely to lower body temperature
