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.

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.

trachea (pl. tracheae)
1. the windpipe; that portion of the respiratory tube that has C-shaped cartilaginous rings and passes from the larynx to two bronchi. 2. tiny air tubes that ramify throughout the insect body for gas exchange. 3.

Insects use tracheal respiration with openings on the sides of the thorax and abdomen called spiracles leading to the tubular tracheal system. Air reaches internal tissues via a network of branches from the tracheal system.

When a bird inhales, air flows in through the trachea to the posterior air sacs, while air currently within the lungs flows into the anterior air sacs.

The direct visualization of the trachea and bronchi through a rigid or flexible tube (bronchoscope). The procedure can be used to remove foreign bodies or to obtain a specimen for biopsy or other examination.

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 paramaecium. Cilia are also found in specialize linings in eukaryotes. For example, cilia sweep fluids past stationary cells in the lining of trachea and ...

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.
