Thermoregulation
When we are too cold, hairs trap a layer of air for insulation.

Thermoregulation

This Biology quiz is called 'Thermoregulation' and it has been written by teachers to help you if you are studying the subject at middle school. Playing educational quizzes is a fabulous way to learn if you are in the 6th, 7th or 8th grade - aged 11 to 14.

It costs only $12.50 per month to play this quiz and over 3,500 others that help you with your school work. You can subscribe on the page at Join Us

Have you ever wondered how we manage to keep cool on hot days or to stay warm when it's snowing? The answer is thermoregulation. Thermoregulation is the control of the internal body temperature in warm blooded animals (birds and mammals - including humans) and in this middle school Biology quiz we find out exactly how thermoregulation works.

1.
Temperature receptors are found in the brain and also in the...
liver
heart
skin
mouth
Skin temperature is constantly monitored
2.
Thermoregulation is the control of body...
fluids
glucose
temperature
pH
Thermoregulation is an example of homeostasis
3.
Receptors inside the thermoregulatory center detect blood...
pH
oxygen
temperature
pressure
The blood flowing through the thermoregulatory center has been heated by passing through the body
4.
During sweating, body temperature...
decreases
increases
remains the same
decreases and then increases
Sweating cools us down, therefore body temperature is decreased back to normal
5.
Which process cools the skin during sweating?
Transpiration
Respiration
Condensation
Evaporation
Sweat contains a lot of water and this evaporates, turning from a liquid into a gas. This takes heat energy away from the body and cools us down
6.
When we are too cold, these trap a layer of air for insulation.
Hairs
Mucus
Sweat glands
Capillaries
The idea is that they trap a layer of air against the skin for insulation. Humans have a lot less skin hair than most mammals and so this is not particularly effective
7.
What is the normal core body temperature for humans?
36 degrees C
37 degrees C
38 degrees C
39 degrees C
It is the core body temperature that matters
8.
This happens when it is cold in order to generate heat from respiration.
Seizures
Crying
Yawning
Shivering
Muscles are made to vibrate and this extra work that they do releases more heat and warms up the blood passing through the muscles
9.
Information about skin temperature is sent to the brain by...
nerve cells
heart cells
brain cells
muscle cells
Nerves are the fast messaging system of the body, so the thrmoregulatory center can respond quickly if needed
10.
The part of the brain which is involved with temperature control is called the...
osmoregulatory center
thermoreceptor center
thermoregulatory center
cortex
'Thermo' indicates something to do with temperature and 'regulatory' indicates the center is something to do with control
