Lung airways. Computer-enhanced image of a resin cast of the airways in the lungs. The trachea (windpipe,top centre) divides into two bronchi,which divide further into small bronchioles. The bronchioles terminate in alveoli (not seen),grape-like clusters of air sacs surrounded by blood vessels. Here the blood takes up oxygen and releases carbon dioxide to be exhaled | |
