Os pulmões pretos de fumantes ocorrem devido ao acúmulo de alcatrão e toxinas da fumaça do cigarro, que causam inflamação e pigmentação escura. Esse alcatrão pegajoso, composto por substâncias cancerígenas, preenche e danifica o tecido pulmonar, levando a doenças como bronquite e enfisema, resultando em sintomas como tosse, falta de ar e aperto no peito. #biologia #medicina #ciencia
