The trachea, colloquially called windpipe, is a tube that connects the pharynx and larynx to the lungs, allowing the passage of air, and so is present in all air-breathing animals with lungs. Only in the lungfish, where the lung is connected to the pharynx and the trachea. The lungs of mammals including those of humans, have a soft, spongelike texture and are honeycombed with epithelium, having a much larger surface area in total than the outer surface area of the lung itself.
