its a bacterial disease. it can present with pneumonia as youve mentioned, as most usually does. but some people just have it in glands, like an enlarged lymph node in their neck because thats where the bacteria is.

What parts of the body are affected by tuberculosis? First and foremost, tuberculosis is a disease of the lungs. However, the infection can spread via blood from the lungs to all organs in the body. This means that you can develop tuberculosis in the pleura (the covering of the lungs), in the bones, the urinary tract and sexual organs, the intestines and even in the skin. Since you are asking only abt its effects on lungs. Thus i am explaining only that. How the bacteria damages the lungs - The bacteria first affect the lungs In pulmonary tuberculosis, "Mycobacterium tuberculosis" bacteria reside in the alveoli and are in close proximity with the alveolar surfactant. Mycolic acid in its free form constitute the major lipids of the mycobacterial cell wall. They can detach from the bacteria easily and are known to be moderately surface active.Mycobacterial cell wall lipids could interact with the pulmonary surfactant and result in lung surfactant dysfunction. These all factors leads to higher surface tension and compressibility values. This leads to the formation of an unstable and fluid surfactant film, which will fail to achieve low surface tensions and can contribute to alveolar collapse in patients suffering from pulmonary tuberculosis. This unstable and fluid surfactant is the liquid you are talking about. Hope this answer will be of some help for you
