Introduction
Relevance of project
The reason I am doing this project is to see what effects smoking has on your body and to conduct research to prove what effects smoking have on your body. The purpose of this research task is to examine the effects of smoking on resting heart rat4 and on heart rate responses during and after exercise
Effects of smoking:
Circulation
When you smoke, the toxins from cigarette smoke enter your blood. The toxins in your blood then:
•Make your blood thicker
•Increase your blood pressure and heart rate
•Narrow your arteries
This increases the chance of your arteries narrowing and clots forming, which can cause a heart attack or stroke.
Heart
Smoking damages your heart and your blood circulation, increasing the risk of conditions such as coronary heart disease, heart attack, stroke, peripheral vascular disease (damaged blood vessels) and cerebrovascular disease (damaged arteries that supply blood to your brain).
Carbon monoxide from the smoke and nicotine both put a strain on the heart by making it work faster. They also increase your risk of blood clots. Other chemicals in cigarette smoke damage the lining of your coronary arteries, leading to furring of the arteries.
In fact, smoking doubles your risk of having a heart attack, and if you smoke you have twice the risk of dying from coronary heart disease than lifetime non-smokers.
Stomach
Smokers have an increased chance of getting stomach cancer or ulcers. Smoking can weaken the muscle that controls the lower end of
