Carbon Dioxide, Water
4 of 28
Name the Organs in the Body Where a lot of Heat is Produced.
Muscles, Liver
5 of 28
Explain Why Extremities May be Cooler than the Rest of the Body.
They lose heat to the surroundings more easily.
6 of 28
List the Places in the Body Where Temperature Receptors Are Found.
Skin, Brain
7 of 28
What is an Effector?
An organ that carries out a response.
8 of 28
Name 2 Effectors used in Controlling Body Temperature.
Sweat Glands, Muscles
9 of 28
What Happens to Body Heat if your Body is Warmer than the Surroundings?
Heat is lost to the surroundings.
10 of 28
Suggest 3 Types of Behaviour that will Reduce Heat Loss.
Put More Clothing On, Curl Up, Huddle Together
11 of 28
Suggest 3 Automatic Response Within the Body to Keep you Warm.
Shivering, Goose Bumps, Less Blood Flows to the Skin's Surface
12 of 28
How does your Body Respond if you are Too Hot?
Sweat is produced, Sweat evaporates which requires heat which is taken from the skin.
13 of 28
What Happens to Blood-Sugar Levels Soon After a Sugary Meal?
Blood sugar levels rise.
14 of 28
Name the Hormone that Controls Blood-Sugar Levels and How Does it Work?
Insulin, It causes the liver to take sugar out of the blood.
15 of 28
What are the Symptoms of Low Blood-Sugar?
Tired, Weak, Irritable
16 of 28

17 of 28
What is the Cause of Type 1 Diabetes?
Genetic, The pancreas cannot make insulin.
18 of 28
What Happens to a Person with Type 1 Diabetes if their Blood-Sugar Drops too Low?
Tired, Weak, Eventually Results in a Coma
19 of 28
Describe 2 Symptoms of Type 1 Diabetes.
Thirst, Large Volumes of Urine
20 of 28
At What Age is Type 2 Diabetes Most Likely to Develop?

Being active all day uses a lot of energy.
24 of 28
What is a Risk Factor?
Something that increase the chance of a disease developing.
25 of 28
Where in the Brain is the Processing Centre to keep your Temperature Constant?
The Hypothalamus
26 of 28
What is Meant by Vasoconstriction? and How Does it Reduce Heat Loss?
This is when blood vessels in the skin narrow to reduce blood flow to the skin. Less blood flow to the skin's surface means less heat is lost to the surroundings.
27 of 28
Explain Why you Look Flushed when you are Hot?
The blood vessels in the skin dilate. More blood flows to the skin's surface and gives it a red colour.
