It gets absorbed into your lungs. My dad once took a white shirt and breathed into it and the shirt turned black were he breathed. It coats the cillia, the small hairs in your lungs, and stops them from being able to absorb as much oxygen. That's why smokers, including myself, get out of breath easier.
Smoking affects the alveoli in the lungs because when the red blood cells absorb oxygen into the alveoli when the smoke is mixing with the clean oxygen it becomes unhealthy for your lungs and dangerous.

Inside your lungs (the organ responsible for you to breathe and live) are little air sacks. They look like tiny little bubbles. They are called alveoli. When you smoke, that smoke goes into your lungs. The smoke is filled with bad things, chemicals and tar. The tar is sticky and covers the alveoli.
The tar and nicotine numb the cilia. When the cilia cannot function, impurities are not removed from the nasal passage. Smoke also harms the alveoli (tiny air sacs) so that the exchange of air in the lungs is impeded.
Tar is a thick dark substance that destroys the alveoli. The alveoli are the microscopic air sacks in the lungs were carbon dioxide is exchanged for oxygen.

Alveoli
No. The "tar" is a sticky residue left when smoke dissolves in the fluid of the lungs. It is not an addictive substance like nicotine, and is only slowly removed from the tissues. Because it can prevent the cilia from cleaning the air in the lungs, and allow toxic substances to reach the alveoli, it is one of the most carcinogenic ingredients in tobacco smoke.
Cilia are hair like structures that brush away particles in your lungs. When you smoke dust, pollen and other particles get stuffed into them and sit there. If they are there for a long time they form tar.
No it's not tar, it's nicotine that is the stimulant.
