treatments for cardiovascular disease including • life-long medication • surgical procedures • lifestyle changes cigarette. Repeat the activity with a lit cigarette in place as shown above. Ask students to describe and, if possible, explain any changes. Emphasise that tobacco smoke contains many substances, and that many are colourless and so not visible.

Identify that there are different kinds of cardiovascular disease, such as heart attack (myocardial infarction), stroke, thrombosis, and angina. Students should research the advantages and disadvantages for each kind of treatment, including which kind of patient responds best to that treatment. the proportion of fat in the body, and why too much fat is a problem. Using yourself or a fit student who won't mind the attention, take measurements of heart rate and breathing rate at rest, after two minutes of gentle exercise and after two minutes of moderate exercise. (Remember to allow raised values to return to resting rates before testing again.) Heart rate can be measured at the wrist or by using a digital heart rate monitor. Breathing rate should be measured as the number of breaths taken in 15 seconds. Explain that the heart rate and breathing rate of people who are very unfit and/or obese usually increase more rapidly than those of fitter people. So, the health professional
