1. In the term "anatomy," "-tom" means
   1. structure
   2. function
   3. cut
   4. small
   
   
2. The most general meaning of "physiology" is
   1. structure
   2. function
   3. biomedical science
   4. disruption of homeostasis
   
   
3. In the "levels of organization," a tissue is considered more complex than
   1. a cell
   2. an organ
   3. both of the above
   4. none of the above
   
   
4. A system that does not have an interface with the external environment is the
   1. respiratory system
   2. digestive system
   3. cardiovascular system
   4. urinary system
   
   
5. The process of excretion usually involves
   1. breaking down food substances
   2. passage of substances into body fluids
   3. moving substances throughout the body in fluids
   4. removal of waste from the body
   
   
6. True or false? Disease results from the body entering a state of "homeostasis."
   1. True.
   2. False.
   
   
7. Structures that monitor some controlled condition (such as blood pressure) are known as
   1. control centers
   2. effectors
   3. receptors
   4. visceral organs
   
   
8. If body temperature is too high, and blood vessels in the skin dilate, the blood vessels are functioning as
   1. controlled conditions
   2. control centers
   3. effectors
   4. receptors
   
   
9. While exercising in a hot environment, the goal of the relevant negative feedback system is to
   1. stop the functioning of the temperature receptors in the brain
   2. stop the production of body heat
   3. cut off blood flow into the skin
   4. increase heat loss from the body so that heat loss exceeds heat production
   
   
10. The pH of body fluids
    1. is a measure of the blood sugar concentration
    2. normally remains at exactly 7.0
    3. normally varies greatly depending on what a person has eaten or drank
    4. normally fluctuates slightly above and slightly below a normal value called the "set point"
    
    
11. According to the principle of negative feedback, a falling blood sugar level leads to
    1. further lowering of the blood sugar level
    2. elevation of the blood sugar level
    3. shut down of the control center for blood sugar regulation
    4. release of insulin and other hormones
    
    
12. The heart and the lungs are located in the
    1. dorsal cavity
    2. vertebral canal
    3. thoracic cavity
    4. abdominopelvic cavity
    
    
13. Which statement accurately describes spinal structure?
    1. The vertebral canal is within the vertebral column.
    2. The spinal cord is within the vertebral canal.
    3. Both of the above.
    4. None of the above.
    
    
14. Which statement is true?
    1. In homeostasis, the function of the control center is to change the set point to accommodate new conditions.
    2. Increases in the level of a controlled condition are normally controlled by positive feedback mechanisms.
    3. Decreases in the level of a controlled condition are normally controlled by negative feedback mechanisms.
    4. All of the above.
