TRACHEA
TRACHEA
The trachea is a long tube that connects the larynx (voice box) to your bronchi. ... Your trachea is an important part of your respiratory system. The trachea is made up of cartilage rings. It is associated with mucus-producing cells. This type of mucus keeps allergies, dust particles, or other debris from entering your lungs.
What is a tracheobronchial tree?
Your trachea is part of your tracheobronchial tree. A tracheobronchial tree is where the air goes to your lungs and exchanges gases (carbon dioxide and oxygen).
Your tracheobronchial tree includes:
Trachea.
Bronchi (BRAWN-kai), large tubes that connect your throat and lungs.
Bronchioles (BRAWN-key-ols), the lower parts of your bronchi become smaller and spread throughout your lungs.

What does the trachea do?
The main function of your trachea is to expel air from your lungs. Because it is a strong, flexible tube, it provides a reliable way for oxygen to enter your body.
How does the throat work in your respiratory system?
Your throat works with your entire respiratory system to help you breathe. When you inhale, the air moves:
From the nose and mouth into the trachea.
From the trachea to your left and right bronchi.
With your bronchi and bronchioles in your lungs.
The tiny sacs in your lungs are called alveoli, where your body exchanges oxygen with carbon dioxide (gas exchange).
When you breathe or exhale, your body takes these steps backward to release carbon dioxide from your body.
How big is the trachea?
For most people, the larynx is 4 inches (10 inches) long - about the width of your hand. It is about an inch (2.5 inches) wide - about as big on the other side as an adult finger.
Where is the trachea found?
Your trachea rests on your lower neck and upper chest, below your larynx. Behind the notch in your lower throat, between the inner edges of your collarbones.
In the drawing of the trachea and other respiratory organs, you can see the larynx between the upper lungs. It is in front of your throat (the tube that carries food from the mouth to your stomach).
What are the parts of the trachea?
The trachea has two parts:
Cervical trachea (in your neck).
Thoracic trachea (your chest).
What is the structure of the trachea?
Your throat is made up of 16 to 20 rings of cartilage. Cartilage is a strong but flexible tissue. It is a major component of your body's connective tissue.
A wet tissue called the mucosa measures each ring of tracheal cartilage. The mucosa contains cells called goblet cells. The shell cells produce a sticky substance called mucus. When you inhale air, mucus traps dust or other small debris so that it does not get into your lungs.
In the inner layer of the trachea, it has small, hair-like structures called cilia. Cilia travels to the pharynx to clear or swallow mucus.
Between each ring of cartilage in the trachea, there is a muscle called the trachealis. When you cough up mucus, your tracheal muscles flex to help you exhale.
What conditions and disorders affect the trachea?
A few conditions can affect your trachea, including:
Throat Cancer: Cancer that begins in the larynx.
Tracheal obstruction: Closure of the upper respiratory tract, including the larynx, throat, or throat (throat).
Tracheal stenosis: A narrowing of the airway that obstructs your breathing.
Tracheitis: Inflammation of the windpipe, usually due to a fever or other infection that causes a cough.
Tracheoesophageal fistula: A abnormal connection (hole) in one or more places between your throat and trachea.
Tracheomalacia: Throat falls between them, usually in newborns.
What causes throat problems?

External throat cramps are the most common and are caused by blurred or permeable cervical or thoracic regions.
How do you treat a swollen throat?
Remedies
It is recommended that you drink plenty of fluids. You can also take off-the-counter painkillers and cough suppressants. Some find that a moisturizer helps help them to breathe easily and release mucus from their lungs.
How long does it take for a sore throat to heal?
