Question

What are the five negative effects of cigarette smoking to circulatory system

Answer 1

Cigarette smoking has several negative effects on the circulatory system, including increased heart rate, reduced oxygen transport, narrowing and weakening of blood vessels, a higher risk of heart attack and stroke, and increased risk of blood clotting.

Step-by-step explanation:

Smoking has several negative effects on the circulatory system:

1. Increased heart rate: Within one minute of inhaling smoke, the heart rate begins to rise, increasing by up to 30 percent in the first 10 minutes.
2. Reduced oxygen transport: Carbon monoxide in tobacco smoke binds with hemoglobin in red blood cells, decreasing the blood's ability to carry oxygen.
3. Narrowing and weakening of blood vessels: Chemicals in tobacco smoke lead to the narrowing and weakening of blood vessels, increasing blood pressure and the risk of blood clot formation.
4. Higher risk of heart attack and stroke: The changes in blood pressure and clotting increase the risk of heart attack and stroke. Smokers are five times more likely to have a heart attack before the age of 40 compared to non-smokers.
5. Increased risk of blood clotting: Smoking increases the substances that contribute to blood clotting, further elevating the risk of cardiovascular problems.
