It has been 30+ years since I learned about TB so I will find a link and post it for you after I write the answer. This is in case I missed anything or got it wrong. Please use the link as backup for the info I suppy as well as a source of more information for you.
TB transmission is human to human, usually via airborn droplets from coughing, sneezing, talking, laughing, etc. These droplets can stay suspended in the air for hours. Someone can then inhale them and the droplets will enter the airways and aveoli. Here, they will multiply and within two weeks enter the lymphatic system. The immune response is activated and granulomas begin to form. When the disease is dormant (inactive), there will be no symptoms but it might show up on an xray and also will register a positive TB test. Dormancy can last for years.
The bad thing about TB is that, once you are infected, the disease can reactivate at any time during your lifetime!
Please use this site...it had an entire section called: pathophysiology.
