The trachea, or windpipe, is held open by cartilage rings. This is to prevent its being squashed closed when a lump of food travels down the adjacent oesophagus.
The trachea (windpipe) is held open by cartilage rings. These rings provide structure and support to the trachea, ensuring that it remains open for the passage of air during breathing.
Cartilage rings provide structural support and maintain the shape of the trachea, allowing it to remain open during breathing. They also protect the trachea from collapsing and help prevent airway obstruction.
cartilage rings give support to trachea to open all the time
cartilage rings
The trachea is a firm cartilaginous tube and is a self supporting structure
rings of cartilage
trachea is also called wind pipe.it is common passage for both food and air.it is kept open by rings.these are of specialised rings which are of "c" shaped .these are made up of cartilage.so, trachea is kept open by 'c' shaped specialised cartilagenous rings. these are made up of special type of cartilage called fibrous cartilage
cartilage
because trachea need support for open all the time and this support is cartilage rings
Rings of cartilage.
trachea has cartilage rings which it open all the time
C-shaped cartilage rings hold open the trachea and the bronchi to prevent them from collapsing when dynamic compression of bronci occurs during exhalation.
