What affects do tar and carbon monoxide have on the bodies of a smoker?

Tar

* Lungs: Tar from cigarette smoke coats the lungs, damaging the cilia (tiny hairs) that help to clear mucus and bacteria from the airways. This can lead to chronic bronchitis, emphysema, and lung cancer.

* Heart: Tar can damage the blood vessels in the heart, increasing the risk of heart disease and stroke.

* Other organs: Tar can also damage the liver, kidneys, and other organs.

Carbon Monoxide

* Blood: Carbon monoxide binds to hemoglobin in the blood, preventing it from carrying oxygen to the cells. This can lead to headaches, dizziness, nausea, and even death.

* Heart: Carbon monoxide can damage the heart muscle, increasing the risk of heart disease.

* Brain: Carbon monoxide can damage the brain, causing memory loss, cognitive impairment, and even dementia.

In addition to these immediate health effects, tar and carbon monoxide can also have long-term consequences, such as an increased risk of cancer, heart disease, and stroke.
