  2. Trachea - Wikipedia

    en.wikipedia.org/wiki/Trachea

    The trachea (pl.: tracheae or tracheas), also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all animals lungs. The trachea extends from the larynx and branches into the two primary bronchi.

  3. Respiratory system of insects - Wikipedia

    en.wikipedia.org/wiki/Respiratory_system_of_insects

    Insects have spiracles on their exoskeletons to allow air to enter the trachea. [1] [page needed] In insects, the tracheal tubes primarily deliver oxygen directly into the insects' tissues. The spiracles can be opened and closed in an efficient manner to reduce water loss. This is done by contracting closer muscles surrounding the spiracle.

  4. Respiratory system - Wikipedia

    en.wikipedia.org/wiki/Respiratory_system

    The trachea is an area of dead space: the oxygen-poor air it contains at the end of exhalation is the first air to re-enter the posterior air sacs and lungs. In comparison to the mammalian respiratory tract , the dead space volume in a bird is, on average, 4.5 times greater than it is in mammals of the same size.

  5. Physiology of underwater diving - Wikipedia

    en.wikipedia.org/wiki/Physiology_of_underwater...

    The heart of a seal is moderately flattened to allow the lungs to deflate. The trachea is flexible enough to collapse under pressure. [16] During deep dives, any remaining air in their bodies is stored in the bronchioles and trachea, which prevents them from experiencing decompression sickness, oxygen toxicity and nitrogen narcosis.

  6. Lung - Wikipedia

    en.wikipedia.org/wiki/Lung

    The trachea receives air from the pharynx and travels down to a place where it splits (the carina) into a right and left primary bronchus. These supply air to the right and left lungs, splitting progressively into the secondary and tertiary bronchi for the lobes of the lungs, and into smaller and smaller bronchioles until they become the ...

  7. Tracheal deviation - Wikipedia

    en.wikipedia.org/wiki/Tracheal_deviation

    However, when tracheal deviation is present, the trachea will be displaced in the direction of less pressure. Meaning, that if one side of the chest cavity has an increase in pressure (such as in the case of a pneumothorax) the trachea will shift towards the opposing side. [1] The trachea is the tube that carries air from the throat to the lungs.

  8. Syrinx (bird anatomy) - Wikipedia

    en.wikipedia.org/wiki/Syrinx_(bird_anatomy)

    Birds do have a larynx, but unlike in mammals, it does not vocalize. The position of the syrinx, structure and musculature varies widely across bird groups. In some groups the syrinx covers the lower end of the trachea and the upper parts of the bronchi in which case the syrinx is said to be tracheobronchial, the most frequent form and the one ...

  9. Voice prosthesis - Wikipedia

    en.wikipedia.org/wiki/Voice_prosthesis

    A voice prosthesis has a one-way valve near the esophageal flange that enables pulmonary air to pass into the esophagus and pharynx for sound production and prevents content from the food pipe, such as liquids or saliva, from entering the trachea.
