The trachea is made of C shaped rings of cartilage, this maintains the shape of the trachea.

cartilage rings
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
the trachea is held open by rings of cartilages
trachea has cartilage rings which it open all the time
the cartilage is important because it open trachea all the time.
The tube is known as the trachea, or windpipe. It serves as a passageway for air to travel in and out of the lungs. The rings of cartilage help keep the trachea open, while the cilia and mucous membrane function to trap and remove any foreign particles or debris from the air before it reaches the lungs.
cartilage rings provides support to the trachea that why it open all the time
epiglottis
The human trachea (windpipe) is kept from caving in by a series of C-shaped cartilage rings that provide structural support while also allowing flexibility for breathing and speaking. These rings prevent the trachea from collapsing during inhalation and exhalation, maintaining an open airway for efficient respiratory function.
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.
Because it stops the blood flowing out
