the epiglottis prevent food to the trachea
The walls of trachea contain c-shaped rings or cartilagenous rings.These soft bones provide rigidity to the trachea , that is why the walls of trachea doesn't collapse when there is less air.
The trachea is reinforced with cartilaginous rings in order to retain the shape while breathing and the rings are incomplete to allow the trachea to expand and move when food passes through the esophagus and while bending the neck.
The cartilage rings in the trachea need to be C shaped so large masses of food can pass through the esophagus during swallowing and large masses of air can pass through the trachea.To allow the oesophagus to expand so that large pieces of food are able to move down into the stomach without getting stuck and tearing the walls of the oesophagus.
The walls of the windpipe (trachea) are made of cartilage rings to prevent collapse and maintain an open passageway for air to flow in and out of the lungs. The stiff material provides support and protection to keep the trachea open during breathing and prevent blockages.
Hyaline cartilage supports the trachea walls. It is very strong but also flexible and elastic, and it has the appearance of frosted glass.
The wall of the trachea is rigid due to the presence of C-shaped cartilage rings that provide structural support and prevent collapse during breathing. These cartilage rings maintain the patency of the airway and help to protect and support the trachea.
cartilage
So it doesn't collapse when you breathe. =]
The trachea is supported by C-shaped rings of cartilage. The point at which there is no cartilage is where the trachea is in contact with the oesophagus. As a large bolus of food passes down the oesophagus the elastic walls expand to accommodate it. This is made possible by the absence of cartilage on the trachea. However, the trachea is prevented from collapsing due to the supporting cartilage around the rest of it.
No, the trachea is a passageway for air to travel to and from the lungs. Oxygen and carbon dioxide are exchanged in the alveoli of the lungs, where they diffuse across the walls of the alveoli and capillaries.
Cartilage is a tough, flexible connective tissue that is present in the walls of the respiratory system, such as the trachea and bronchi. It provides structural support and helps to keep the airways open during breathing.
The trachea is maintained in an open position by C-shaped rings of hyaline cartilage along its walls. These rings provide structural support to prevent collapse during breathing while allowing flexibility for movement and expansion.
