welll if you smoke your lungs become bad because all the chemicals you are inhaling is making your lungs weeker and weeker it also messes your teeth up because you are inhaling all the chemicals you and damaging your teeth and it makes then black and the fall ou t
Mainly it causes increased infections of the lung tissues,

and as lung tissue is slowly replaces by scar tissue you get COPD

(chronic obstructive pulmonary disease)

which will eventually kill you due to shortness of breath.

Cancer is incidental to the fact that infections and chemical irritants cause cells to reproduce - and each reproduction is susceptible to errors (including cancer).

Smoking harms the Cardiovascular system by reducing levels of high-density lipoproteins ("good" cholesterol"), and raising levels of triglycerides and low-density lipoproteins ("bad" cholesterol"). It also increases blood pressure and heart rate, while reducing the amount of oxygen available to the body. It makes the platelets in blood become sticky, promoting clotting, and permanently accelerates the rate at which fatty deposits are laid down in arteries.

Acids can denature enzymes and make them less active or completely inactive. Denaturation causes a change in the three-dimensional structure of an enzyme which can affect the function of the enzyme.


What other body parts does smoking affect?

Besides your lungs, your heart is also at risk when you puff smoke. There's a connection between the lungs and the heart, because when you breathe in polluted or intoxicated air, the person's cardio-respiratory system is involved. There might also be other organs which can be affected by smoking. I'm just not sure if the liver is one of those. Yes, depending on the substance that is being smoked, it can affect a person's liver. Certian smokes can also affect a person's brain, circulatory system, nervous system, respiratory system, and occasionaly the reproductive and endocrine system.


What cells perform different functions?

Different cells are different in structure because of their different functions (e.g. plant cells have cell walls because they don't have bones). Also, cells have different functions because they work together with other cells to create a working system (e.g. the human body)
