Why trachea close?

The trachea does not usually close. It is a rigid tube that connects the larynx (voice box) to the lungs. However, there are a few conditions that can cause the trachea to narrow or close, such as:

- Laryngospasm: This is a sudden, involuntary contraction of the muscles of the larynx. It can be caused by a variety of things, such as allergies, asthma, or certain medications. Laryngospasm can make it difficult to breathe, and in severe cases, it can lead to suffocation.

- Tracheal stenosis: This is a narrowing of the trachea that can be caused by a variety of things, such as scarring, tumors, or birth defects. Tracheal stenosis can make it difficult to breathe, and in severe cases, it can lead to suffocation.

- Tracheomalacia: This is a condition in which the trachea is weak and floppy. It can be caused by a variety of things, such as aging, chronic bronchitis, or emphysema. Tracheomalacia can make it difficult to breathe, and in severe cases, it can lead to suffocation.

If you are experiencing difficulty breathing, it is important to see a doctor right away.
