Ch. 1 Anatomy and Physiology for
Emergency Care Exam Questions
and Answers
What does thermoregulation involve? - Answer- Altering the relationship between heat
loss and heat production.
How does your body regulate temperature if it rises? - Answer- The thermoregulatory
control center in located in the brain. Temperature receptors are located in the skin and
in cells in the control center. Normal temp is 98.6. If it rises, the control center tragets
two effectors: (1) smooth muscles in the walls of blood vessels that supply the skin and
(2) sweat glands. The muscle tissue relaxes and blood vessels widen that inturn
increases blood flow and the sweat glands accelerate their secretion. Skin acts like
radiator and loses heat to environment and evaporation of sweat speeds process. Temp
returns to normal, thermoregulator center becomes inactive till needed again.
How does the body regulate temp. if it drops? - Answer- The control center targets the
same two effectors but this time the blood flow declines and sweat activity decreases.
This combo reduces the rate of heat loss to the environment. Due to heat production
still continuing in the body the temp. balance with level and everything goes back to
normal resting levels.
What is positive feedback? - Answer- It is the initial stimulus produced from a response
that reinforces that stimulus.
What is an example of positive feedback? - Answer- Blood clotting. When you get
injured and your recieve a cut, the damaged blood vessel wall releases chemicals that
begin the multistep process of blood clotting. As clotting gets underway, each step
releases chemicals taht accelerate the process. That accelerated process is a positive
feedback.

embrace" , Brachium refers to the arm
