Trachea Function


tracheaThe trachea is a human body part that plays a major role in your life and breadth. Without its 100% functions in your breathing abilities you would not be able to live. The trachea is also known as your windpipe that fastens the respiratory system to your larnyx. It allows you to breathe through its 4-5 inch long tubular shape. Its diameter measures at a little under one full inch.

The trachea sets at the bottom of the larnyx (voice box) and then runs its tubular course to the sternum (center chest bone.) It then forks into 2 different tubes that are small in size referred to as bronchi. While during in and out breaths the trachea expands and contracts.

Trachea Function & Roles in the Body

Among aiding in breathing the windpipe (trachea) performs several important functions in the body including:

1. Breathing function:

The main function of your trachea is to enable the passage of the air that you breathe. It then passes through the windpipe and is transferred into your lungs. This function is known as respiration. After the air travels down the trachea it then divides into the two bronchi for each lungs. From the bronchi oxygen then passes to the bronchioles and after it reaches the alveoli. The trachea can suffer from injuries occasionally whether it is blocked from choking or collapses from direct trauma. Depending on the severity it can be life threatening if your trachea functions are compromised.

2. Immunity:

Above its primary role in respiratory functions, the trachea can also assist in boosting your immunity and keeping it from pollutants that pose health risks. It helps you to protect yourself from substances, toxins, and microbes that can be breathed into the lungs. How does it protect you?

The trachea is lined with thick phlegm which helps to collect and capture any foreign particles. The harmful particles can be coughed up through the mucus or swallowed and processed through the digestive system. If anything does make it to the trachea usually coughing expels the materials so that they are not of compromise to your breathing capacities.

3. Aids in Digestion:

Another main part of how the Trachea functions in the human body is that it is also a significant aid in the process of digestion. It is the reason that when you consumer liquids or food that you can swallow your food. When the trachea is blocked by food, objects, or from something else you choke. Most times the object or food will eject from your mouth naturally or with the help of CPR techniques, however there are times that a person will die if the object is trapped to long and oxygen relief is compromised.

4. Temperature Regulation:

The Trachea works diligently to maintain and regulate temperature of the substances and particles that travels down it. It also controls the temperature by warming or humidifying the air in which you breathe. If your temperature is hot it will attempt to help to cool it down and vice versa.

Other Organs that Aid Respiratory Function

Besides the trachea there are many other respiratory organs that work to help manage respiratory function in the body including:

The Lungs

The lungs as you may already know primarily function to help you breathe in oxygen and out carbon dioxide. They are essential for human life. The cells in your body need oxygen constantly in order to function. Without proper oxygen in your blood stream you can die.

The Nostrils 

The nostrils are located in your nose, Although you can inhale and exhale through your mouth the nostrils also help you to exhale and inhale air and the oxygen in it. Hairs contained in your nostrils are called cilia. These cilia help to filter and collect particles, dust and other small substances that you can breathe in through air.

The Diaphragm

The diaphragm is a muscle in your chest that lies on the bottom of each lung. It is dome-shaped and is the muscle which breathing in the body starts. As you breathe air in your diaphragm is pushed downward, as it flattens and contracts. When this occurs the lung’s capacity increases. The opposite happens when you breathe out, the lungs retract and its capacity is reduced.

The Alveolus

The Alveolus is a very small sac located in your lung region, It functions to help turn oxygen into carbon dioxide.

Trachea Related Health Conditions

There are many conditions that can impact the trachea including, tracheal fistula, tracheal obstruction, tracheal stenosis, tracheal cancer, and more.

Since the trachea plays such an important role in breathing and tracheal functions are absolutely necessary for you to survive , thrive, and live- you should make absolutely certain you take care of yourself. Be sure to chew your food well, stay away from dangerous situations, do not chew on foreign objects, and always tell you family practitioner if you are experiencing problems in your trachea.
