5 Pick a system of the body, and describe the ways in which smoking harms it. Respiratory System- Tobacco smoke releases tar, which damages the alveoli, which results in less oxygen to your body. Emphysema can occur. You risk lung cancer if you continue to smoke.

Circulatory System- As nicotine enters the blood stream, vessels constrict, and over time these vessels can harden. There is not enough oxygen carried to the body parts that need this oxygen. Blood pressure rises and heart rate speeds up which increases chance of stroke, heart attack and heart disease.

Nervous system- When you smoke, carbon monoxide is released in the smoke. This carbon monoxide cuts down on the amount of oxygen reaching the brain.

Digestive System Smoking can cause mouth and stomach ulcers, which are painful sores. When this happens, these smokers may not be able to eat certain foods, which harms their nutrition. Smoking also harms teeth and gums, which lead to more cavities and gum disease.

Excretory system Smokers are more likely to develop bladder cancer. The chemicals from smoke get into the blood stream and are then filtered by the kidneys. The kidneys put these chemicals into the bladder, which increases the chance of bladder cancer. Colorectal cancer is also a possibility.
