Tar is the sticky substance that is found on tobacco leaves, when smoked this sticky substance coats the inside of your lungs and air sacks- preventing oxygen from reaching the circulatory system.
Tar is an irritant. It enters the respiratory system as an aerosol of minute droplets which are deposited in the respiratory system causing excessive mucus production. Tar destroys the cilia and thus inhibits the sweeping up of mucus to the back of the throat. Mucus together with its trapped particles slides down into the lungs increasing the risk of infections, and damage. Tar also contains carcinogens which combine with the affected mucus membranes. It causes lung cancer, chronic bronchitis and also emphysema.
-there is a lining in the bronciole and bronchus which forms a protective layer. Tar makes them divide and some of the cells go on dividing which developes into cancer.
- Tar is irritant which causes extra mucus to be made by the goblet cells in the trachea. The mucus trickles down and the cilia are no longer able to sweep it upwards causing "chronic bronchitis" (fever, chest pain, tiredness)
- Bacteria breeds in the mucus causing infections. The person coughs to try to move the mucus upwards causing damage to the delicate alveoli in the lungs. This makes it difficult for the person to get oxygen in his/her blood. Which causes "emphysema" (breathing difficulties)
when you inhale it so much of it goes into your lungs and so much of it goes into your bloodstream it makes your lungs black and over a long period of time all that tar will build up in your lungs and it will be hard to breathe

Cigarettes contain many harmful ingredients like Tar, Arsenic (which is a poison), Nicotine (this is what makes you addicted to the cigarette) etc. The effect to the respiratory system varies from how much and the period of time you have been smoking. The damage to the respiratory system is the Alvoli in your lungs (Look like little sacs in your lungs) die and your lungs go black from the tar in the cigarette.
