Two things hold the trachea open
1. air pressure
2. Cartilidge rings that the trachea is made of catilaginous rings.
If a patient has had a tracheostomy and the cannula (the plastic device that keeps the trachea open) is removed, the area is covered with gauze and will close on its own in time.
Hope this helps

Rings of cartilage.
the trachea is held open by rings of cartilages
trachea has cartilage rings which it open all the time
The trachea is made of C shaped rings of cartilage, this maintains the shape of the trachea.
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
The esophagus is open to the mouth and the stomach to allow food and liquids to pass. The trachea is open to the nose and mouth, leading to the lungs to facilitate breathing and air flow.
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.
What keeps the trachea open are small cartilage ring, called cricoid cartilage.
Because it stops the blood flowing out
