    well,, it is basically droplet disease so when the healthy person breath in these droplet release from infected person……so when the mycobacterium enters the lungs…. WBC called phagocyte engulf it and began to form shell around it keeping it under control.. at next stage tubercles are develop which find a suitable environment for growing in the macrophages then it began to invade the bronchi oles and eventually destroy the cells of lungs…….causing TB………
    (if not right……sorii……i m just beginner here of 16 yrs old……)
