Explanation of Names
From Latin trachea windpipe; from Greek tracheia (arteria), the rough "artery", from Greek trachys rough (Jardine and Internet searches).
Identification
trachea noun, plural tracheae, adjective tracheal - the organs of respiration in insects; they are simple tubes which communicate externally with the air by means of spiracles, and internally with the blood. From each spiracle a single trachea enters the body. If the tracheae upon entering the body separate, diverge, or ramify throughout the region in their immediate vicinity without any obvious connection with the tracheae of the adjoining spiracles, they are said to be detached; and connected when there is a grand longitudinal trachea traversing each side of the body throughout its length, into which each spiracle sends its particular trachea, sometimes as a single tube, sometimes after a slight ramification (Jardine).
