The air we breathe goes through the trachea or windpipe, which separates into two branches, called bronchial tubes or bronchi, one entering each lung. The bronchi subdivide many times inside the lungs, analogous to the branching pattern of the grapes, finally becoming hairlike tubes called bronchioles. In the last part of the terminal bronchioles are tiny bubble-like bunch of structures called alveoli or aisacs.
