What is bood pressure measured in?
Millimetres of mercury (mmHg).
1 of 18
What is Systolic pressure?
Systolic pressure is the maximum pressure produced by the heartbeat.
2 of 18
What is Diastolic pressure?
Diastolic pressure is the bood pressure produced when the heart is resting between heart beats.
3 of 18
How can blood pressure be increased?
Blood pressure can be increased by stress, high alcohol intake, smoking and being overweight.
4 of 18
How can blood pressure be decreased?
Blood pressure can be decreased by doing regular exercise and eating a balanced diet.
5 of 18
What are the consequences of having high blood pressure?
High blood pressure can cause damage to the brain/strokes and damage to the kidney.
6 of 18
What are the consequences of low blood pressure?
Low blood pressure can cause dizziness and fainting because a lack of pressure reduces circulation and blood supply to the brain and sometimes other areas of the body.
7 of 18
What is a normal blood pressure?
120/70. Where the systolic pressure is 120 and the diastolic pressure is 70.

What is the difference between fitness and health?
Fitness is the ability to perform physical activity while health is the amount of freedom from disease.
9 of 18
How can general fitness level be assessed?
General fitness level can be assessed by a person's cardiovascular efficiency.
10 of 18
How else can fitness be assessed?
A person's strength, agility, flexibility, stamina and speed can also assess their level of fitness.

How does Carbon Dioxide in cigarette smoke increase blood pressure?
Cigarette smoke contains carbon dioxide, when carbon dioxide is inhaled it reduces the oxygen carrying ability of the blood. This causes the heart to beat faster and the blood pressure to rise to enabled more oxygen to be carried to muscle tissues.
12 of 18
How does Carbon Dioxide reduce the oxygen carrying capacity of the blood?
Carbon dioxide binds with haemoglobin in place of oxygen, so less oxygen can be carried in the blood stream.
13 of 18
Which addictive toxin in cigarettes increases blood pressure directly?
Nicotine.
14 of 18
What causes heart disease?
A restricted flow of blood to the heart muscle.
15 of 18
Which two dietary factors can cause heart disease and how?
High saturated-fat diet - this leads to a build up or cholesterol (a plaque) in the arteries. High salt diet - leads to high blood pressure.
16 of 18
How does a build up of cholesterol in the arteries cause heart disease?
The arteries are narrowed due to the build up of cholesterol within them which reduces blood flow to the heart.
17 of 18
What is thrombosis?
Thrombosis is clotting of blood. Blood clots can block the coronary arteries and lead to heart disease.
