Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds.

The splint helps strengthen the trachea with the hopes that the symptoms improve. [2] People with tracheobronchomalacia who do not experience symptoms do not need treatment and are often undiagnosed. [2] On 28 May 2013, it was reported that a cure had been developed via a 3D printed windpipe. [14]
Tracheomalacia is a condition or incident where the cartilage that keeps the airway (trachea) open is soft such that the trachea partly collapses especially during increased airflow. This condition is most commonly seen in infants and young children. [ 2 ]
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.
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.
In babies and young children however, the subglottis is the narrowest part of the airway and most stenoses do in fact occur at this level. Subglottic stenosis is often therefore used to describe central airway narrowing in children, and laryngotracheal stenosis is more often used in adults.
However, simply petting a dog is extremely good for us – it lowers the stress hormone cortisol, while social interaction between humans and dogs increases our levels of oxytocin, the feel-good ...
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.
