Question

1. Explain why Lung smokers, Lung normal and Lung metastatic appear different?

Answer 1

These three cases are different in its characteristics & hence has different appearance. Tobacco smoke contains several chemicals that can hurt the respiratory system. The chemicals cause inflammation in lungs which results in ecxess mucus production & due to this, smokers have a high chance of getting affected by pneumonia, bronchitis, etc. The most dangerous chemical in tobacco is nicotine which immobilise cilia. The cellular structure of the organ is altered by the chemicals. After quitting smoking, the cilia starts regeneration and the lungs starts to heal and regain its general structure. In some weeks, the lungs becomes functional as it's supposed to be. On the other hand, Metastatic lungs are those lungs affected by tumors (cancerous) which does not originated in the lungs but from another organ.
