Bronchial tubes. two tubes at the end of the trachea, brings in air from trachea and helps clean lungs; one tube goes to right lung, one to left. Tuberculosis (TB). Once very common; incidence declined in industrialized nations as living standards improved. In 1985, incidence began to rise due to expanding AIDS epidemic, increasing prevalence of drug-resistant strains. Transports air into the lungs and facilitates the diffusion of oxygen into the blood stream. Receives carbon dioxide from the blood and exhales it. Organs of the Respiratory system. Slide 13.1.
