- Blood leaves heart at a high pressure and gets lower as it flows through the system.
- Systolic pressure- heart contracts and pressure is at its highest. Diastolic pressure- heart relaxes and pressure is at its lowest.
- Blood pressure measured in mmHg (millimetres of mercury).
- In a healthy person the systolic pressure shouldn't be higher than 135 over 85 in diastolic pressure.
- Factors that increase blood pressure- smoking, being overweight, a lot of alcohol and a lot of stress.
- High blood pressure causes blood vessels to burst leading to strokes, brain damage and kidney damage.
- Can be decreased by lifestyle changes, e.g. balanced diet or regular exercise- drugs used in extreme cases.
- Low blood pressure can cause poor circulation meaning not all tissues get the oxygen needed- causes dizziness and fainting.
- Can also be treated by making lifestyle changes such as eating a diet higher in salt.
