False colouor scanning electron micrograph of the inner surface of the human bronchus (1 of the 2 main forks of the trachea - windpipe,which supply the lungs),showing the margin of growth of cancerous cells (over majority of image ) of a bronchial tumour and ciliated epithelia (which may be normal) towards bottom left. Normal epithelia is capable of warming,humidifying & filtering incoming air - the beat of the feathery cilia serve to expel any foreign particles. Cancers of bronchi & lung are common in western countries & are strongly linked to cigarette smoking & exposure to air pollutants (including asbestos). Magnification: X32 at 35mm size.
