How does the body know these external things are
|\ |\ |\ |\ |\ |\ |\ |\ |\
happening? - CORRECT ANSWERS ✔✔The body knows |\ |\ |\ |\ |\ |\ |\
these external things are happening due to the control
|\ |\ |\ |\ |\ |\ |\ |\ |\
system as a stimulus is presented it causes the body to
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
have negative feedback as it tries to maintain
|\ |\ |\ |\ |\ |\ |\ |\
homeostasis.
Why is it necessary to keep the body at a certain
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
temperature to protect from UV radiation? - CORRECT |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔It is important to keep the body at a certain
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
temperature because if the body exceeds a certain |\ |\ |\ |\ |\ |\ |\ |\
temperature an athlete may go into heat exhaustion or |\ |\ |\ |\ |\ |\ |\ |\ |\
possible heat stroke. It is equally important to protect the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
body from UV radiation
|\ |\ |\
Why does the athlete's body release adrenaline
|\ |\ |\ |\ |\ |\ |\
(epinephrine) before the race has even started? - |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔When the heart rate increases |\ |\ |\ |\ |\ |\ |\
before the race, more blood is being pumped which is
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
giving the athlete more fuel causing adrenaline
|\ |\ |\ |\ |\ |\ |\
(epinephrine) to enter the bloodstream |\ |\ |\ |\
Once the race has started, the first changes we see are
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
increased heart rate and blood pressure. What is the
|\ |\ |\ |\ |\ |\ |\ |\ |\
, purpose of this rapid increase in blood flow? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔The heart rate and blood pressure increased |\ |\ |\ |\ |\ |\ |\
after the race started due to the muscles working and
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
need more oxygen in result produced more waste gas.
|\ |\ |\ |\ |\ |\ |\ |\ |\
Oxygen supply from the lungs is involved means more
|\ |\ |\ |\ |\ |\ |\ |\ |\
work for the lungs and also more blood needed to carry
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
oxygen to the muscles, the heart has to work harder
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
making the heart beat more quickly and the heart rate
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
increases.
How does the body increase its oxygen supply? -
|\ |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔Oxygen supply from the lungs is |\ |\ |\ |\ |\ |\ |\ |\
involved resulting in more work for the lungs due to the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
muscles needing more oxygen as a lot of waste gas has
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
been produced. |\
Why do the runners look flushed only 20 minutes into the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
race? - CORRECT ANSWERS ✔✔As the body heats up due
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
to running it causes the body temperature to increase
|\ |\ |\ |\ |\ |\ |\ |\ |\
and as a result the body can begin to stop functioning if
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
the temperature reaches a dangerously high
|\ |\ |\ |\ |\ |\
temperature.
The runners take regular drinks of glucose and water.
|\ |\ |\ |\ |\ |\ |\ |\ |\
What do these two substances do for the body during the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
race? - CORRECT ANSWERS ✔✔During the race, the water
|\ |\ |\ |\ |\ |\ |\ |\
and glucose help the body as it helps to replenish the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
