1. B – The Cardiovascular System
The structure and function of arteries, capillaries and veins
The structure and function of the heart
Pathology of cardio vascular disease (CVD)
Blood glucose levels and obesity

2. KA 6d: Learning Outcomes
State what blood pressure is
Describe how blood pressure can be measured
Explain how systolic and diastolic pressure are detected
State the typical blood pressure reading for a young adult
State what is meant by hypertension
State the link between by hypertension and coronary heart disease

3. How is blood pressure measured?
What is blood pressure?
How is blood pressure measured?

4. Brachial Artery Use a sphygmomanometer
First pressure reading after an inflatable cuff stops blood flow and deflates gradually, causing the blood to start to flow (detected by a pulse) at systolic pressure.
Second reading taken when the blood flows freely through the artery (and a pulse is not detected) at diastolic pressure.
Brachial Artery

5. Blood pressure cuff (sphygmomanometer)
A maximum (systolic) and a minimum (diastolic) pressure is given
3 values are given:
Sys (systole)
Dia (diastole
Pulse

6. Blood Pressure changes through the blood vessels
A typical reading for a young adult is 120/70 mmHg (millimetres of Mercury)

7. Hypertension AKA High blood pressure
Hypertension is a major risk factor for many diseases including coronary heart disease.
The Silent Killer (5:13)
