The effects of smoking on the body system


When you inhale a cigarette it goes from your mouth down your throat past your pharynx and your trachea into the bronchioles and into the lungs. The inhaled cigarettes have tar in them which is sticky and brown and it can cause damage to your body.
It can cause damage to your teeth, mouth and gums as well as ulcers of the digestive system. The carbon monoxide binds with hemoglobin and takes over the oxygen carried by the blood. So with there being less oxygen in the blood cells your heart has to pump more so the body gets the amount of oxygen which is needed.
Hydrogen cyanide prevents the lungs from cleaning themselves and the cilia becomes damaged, harmful chemicals collect in the lungs. Other chemicals in smoke are highly reactive chemicals that can damage heart muscles and blood vessels. Cigarettes also include dangerous metals which many are known to cause cancer. The tar in cigarettes can cause cancer of the esophagus and throat. Smoking increases stomach acids which can lead to ulcers and higher rates of pancreatic cancer. Carcinogen from cigarettes are excreted in your urine which can cause bladder cancer and high blood pressure from smoking can cause damage to your kidneys.
Fertility is compromised, in female smokers it can affect the reproductive system and they are also high risk of getting cervical cancer and men tend to have lower sperm count because of the damaged blood vessels in the penis.
Smokers immune systems are vulnerable and they are very prone to minor infections such as chest infection.
