Animation: Immunology of the lung

Our lungs bring in vital oxygen and expel carbon dioxide but they are also usually the first site of pathogen exposure. To counter this impending threat, the lungs have their own large and complex immune system. This filters the air we breathe, repulses invaders and repairs injury. Sometimes these powerful immune responses overreact or are misdirected causing diseases such as asthma. This animation introduces the cells and immunological processes underlying the initiation and pathogenesis of asthma.
