Tracheal Breathing
Insects, and some other invertebrates, exchange oxygen and carbon dioxide between their tissues and the air by a system of air-filled tubes called tracheae.

The Trachea and Bronchi
The trachea or windpipe (Fig. 961) is a cartilaginous and membranous tube, extending from the lower part of the larynx, on a level with the sixth cervical vertebra, to the upper border of the fifth thoracic vertebra, ...
Tracheal Systems
Many terrestrial animals have their respiratory surfaces inside the body and connected to the outside by a series of tubes.Tracheae are these tubes that carry air directly to cells for gas exchange.
tracheae -- Internal tubes through which air is taken for respiration.
trachea
(tray-kee-uh)
The windpipe; that portion of the respiratory tube that has C-shaped cartilagenous rings and passes from the larynx to two bronchi.

trachea - the larger respiratory tubes leading from the spiracles to the interior in insects, to allow O2 uptake and CO2 discharge.

trachea The windpipe. Also, any of the air tubes of insects.
tracheae The small tubes that carry air from spiracles through the body cavity of an arthropod; arthropod tracheae are modifications of the exoskeleton.
In humans, the trachea divides into the two main bronchi that enter the roots of the lungs. The bronchi continue to divide within the lung, and after multiple divisions, give rise to bronchioles.
We can divide the plants into two groups, the bryophytes (literally meaning moss plants) and tracheophytes (plants with trachea or "pipes").
Terrestrial forms have book lungs (e.g., spiders) or tracheae. (e.g., insects). Book lungs are invaginations to serve in gas exchange between air and blood. Tracheae are air tubes that serve as ways to deliver oxygen directly to cells.
A cartilaginous structure at the top of the trachea; contains elastic vocal cords that are the source of the vocal tone in speech.
Xylem cells are also known as tracheary elements . This name was applied by Marcello Malpighi after noticing similarities between the tracheae of insects and xylem cells.

spiracle. An external opening of the system of ducts, or tracheae, that serves as a respiratory system in insects.
sporangium (plural: sporangia). A structure in which asexual spores are produced.
Spiracles: The external openings of the insect breathing (tracheal) system, found along the abdomen.
Cells lining the human upper respiratory tract are ciliated (have cilia). The cilia move mucous and debris upward to the mouth where it is swallowed. The photograph below is a cross section of a human trachea (400 X).
Cilia are hair-like structures that can beat in synchrony causing the movement of unicellular paramecium. Cilia are also found in specialize linings in eukaryotes. For example, cilia sweep fluids past stationary cells in the lining of trachea and ...
Your respiratory system is made of your nose and mouth, a tube called the pharynx, another tube called the trachea, and your lungs. You have two lungs and the exchange of gases between the circulatory and respiratory systems happens in the lungs.
In the lantern, nitric oxide synthase is expressed in tracheal end cells that are interposed between neuron terminals and photocytes. Exogenous NO can activate light production and NO scavengers block evoked flashes.
