The etymology of the word tracheotomy comes from two Greek words: the root tom-(from Greek τομή tomḗ) meaning "to cut", and the word trachea (from Greek τραχεία tracheía). [2] The word tracheostomy , including the root stom- (from Greek στόμα stóma ) meaning "mouth", refers to the making of a semi-permanent or permanent ...
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.

The most common tracheal injury is a tear near the carina or in the membranous wall of the trachea. [15] In blunt chest trauma, TBI occurs within 2.5 cm of the carina 40–80% of the time. [ 2 ] The injury is more common in the right main bronchus than the left, possibly because the former is near vertebrae , which may injure it. [ 2 ]
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 ...
The trachea are covered in partly ossified rings known as tracheal rings. Tracheal rings tend to be complete, while the bronchial rings are C-shaped and the unossified part has smooth muscles running along them. The trachea are usual circular or oval in cross section in most birds but are flattened in ibises.
A tracheotome is a medical instrument used to perform an incision in the trachea with a cutting blade operated by a powered cannula. It is often called a tracheostomy tube because once it enters the stoma in the trachea, a breathing tube is connected to a ventilator and oxygen is provided to the lungs. There are different types of tracheotomes.
Rather than a lute, the hieroglyph is actually a representation of the heart and trachea. [1] It originally may have been the esophagus and heart. The striations of the windpipe only appear in the hieroglyph following the Old Kingdom of Egypt .
