why is the blood in the arteries under pressure?
1) due to contraction os heart muscles 2) so that blood reaches all parts of the body
1 of 15
what factors increase the risk of developing heart disease?
1) high blood pressure 2) smoking 3) eating high levels of salt 4) eating high levels of saturated fats
2 of 15
how does cholestrol restrict or block blood flowing in the arteries?
1) cholestrol forms plaques 2) the plaque bukges into the lumen 3) this restricts the flow of blood thorugh the arteries
3 of 15
how is blood pressure measured?
1) mmHg (millimetres of mercury 2) it is represented by two measurements 3) systolic and diastolic
4 of 15
what is systolic pressure?
1) the first number 2) the pressure in your arteries when the heart CONTRACTS
5 of 15
what is diastolic pressure?
1) the seconds number 2) the pressure in the arteries when the heart RELAXES
6 of 15
what factors increase blood pressure?
1) being overweight 2) stress 3) high alcohol intake 4) smoking
7 of 15
what factors decrease blood pressure?
1) regular exercise 2) balanced diet
8 of 15
what is fitness?
1) the ability to do physical activity 2) how much physical activity your capable of doing and how quickly your body recovers afterwards
9 of 15
what is health?
1) being free from disease 2) being free from infection
10 of 15
what are the different ways of measuring fitness?
1) strength 2) stamina 3) flexibiltity 4) agility 5) speed 6) cardiovascular effeciency

what are the possible links between the amount of saturated fat eaten, the build up of cholestrol plaques and the insidence of heart disease?
1) the more saturated fat you eat, the more cholestrol plaques build up 2) increasing the risks of heart disease
13 of 15
what are the possible consequences of having high blood pressure?
1) blood vessels can weaken and eventually burst 2) if a blood vessel bursts in the brain it can cause serious brain damage or stroke 3) if it bursts in the kidney it may kead to kidney damage
14 of 15
what are the possible consequences of having low blood pressure?
1) blood doesnt circulate effeciantly 2) therefore some parts of the body are deprived of glucose and oxygen 3) dizziness, fainting and cold hands and feet 2) pressure may drop in the kidney leading to kidney failure
