We all know that the main function of the throat is to swallow and gulp anything placed inside the mouth. But in reality throat does several functions throughout the day and night in keeping you alive. Throat serves as an excellent transport system meant for moving air, fluids and any solids.
It is the trachea inside the throat that receives oxygen pushing it into the lungs. One can feel the pulse of heart by gently pressing the throat. Throat starts functioning from the minute the baby is born and continues to function until he dies.
Every organ in human body has been devised meticulously in proper shape and size suiting the way it functions. Accordingly throat is a narrow elongated part connecting your head to the shoulders. Throat begins at the back of your mouth and ends in the upper part of the stomach.
As long as a person is alive throat functions non-stop helping in breathing and swallowing. And once your throat stops functioning normally you would have pain or difficulty in breathing/swallowing and if it is strangulated you would die.
The throat can be defined as the anterior part of the neck in general terms. In the anatomical terms, it is the segment of the digestive tract that begins from the back of the mouth. A throat is very soft and delicate organ that gets easily irritated causing painful sores and ulcers.
Based on anatomy, throat can be divided into 3 parts namely, the upper part , the middle part and the lower part called as nasopharynx , oropharynx and laryngopharynx respectively.
It is the larynx that is responsible for diverting the food or fluids into the stomach and not into the lungs. Whenever you eat/drink something the larynx slightly rises making the epiglottis to move up and down over the glottis.
This creates a tight seal over it thus not allowing food particles into the lungs. In rare cases food or fluids can enter into the trachea by mistake. But it automatically creates coughing expelling the food outside so that it does not block the airway.
Similarly food particles do not enter into the nasal cavity or block its path. A small tissue flap (uvula) found at the back of soft palate of the mouth rises up to cover the nasal path located above. Thus the larynx is built with excellent switching mechanism so that you will not send food particles in the wrong way. Even when a person stands on his head (like in yoga posture) the saliva will not enter into the trachea by this mechanism.
The throat is designed to perform precise events in proper timing which keeps you alive all the time. Any abnormal changes in your throat persisting for few minutes will collapse the person. Throat is considered as an excellent transportation media switching and moving tissues and cartilages to allow transfer of air and food particles at equal pace. The neck is complex organ loaded with blood vessels, nerves, tubes and cartilages. The major function of the throat lies in organizing the exchange of air and sending the food particles into the right path thus managing two separate channels efficiently.
When a person coughs or sneezes he expels the irritants that have traveled in the wrong path thus protecting the windpipe and lungs. Coughing is the involuntary defense mechanism designed by the throat to catch and punish the trespasser quickly. By the act of coughing, the throat would expel the irritant material with such a force that it gets out not only from the mouth but it is thrown out a few miles away.
At the sight or smell of food the salivary glands secrete excess of saliva. Once you put some food into the mouth the saliva mixes with food and as your teeth chews it to break down the particles into small pieces. When the mouth gets filled with food the tongue pushes the mass through the throat sending it into the esophagus. Several muscles work rhythmically to push down the food through pharynx. In the meantime, the larynx closes automatically to prevent any food particles to escape into the trachea.
Air is pushed down with force through the larynx when a person talks. The larynx or voice cord consists of several folds of tissue that produces vibration in response to the pressure of air applied on the folds. Volume and intensity and nature of voice vary according to the air that is pushed into the larynx. Continuous stretching and relaxing of folds of tissue on the larynx produce noise and that is how we talk or sing.
The throat is the only way for transporting air and food and hence it becomes the primary target for micro-organisms. The throat is constantly invaded by millions of bacteria and fungi. The thick mucus blanket lining and the tonsils helps in moving them away from the throat. But sometimes the invaders are more powerful than the parts of throat causing irritation of the lining resulting in sore throat .
Among the parts of the throat, larynx becomes the target for major pollutants and invaders. Any type of smoke, fumes and automobile exhausts can affect the larynx causing laryngitis. The voice gets damaged making it hoarse. Larynx is at risk of developing cancer when a person smokes a cigar. If your voice is not normal for more than a week you need to check with your GP to prevent any complication.

The throat comprises of air and food passageways lying behind the nasal cavity and mouth and in the neck. It consists (from the top to the bottom) of the pharynx, epiglottis, larynx (voice box with vocal cords) and the upper part of the esophagus and trachea ( Picture 1 ).

The pharynx is a muscular tube lying behind the nasal cavity and mouth, carrying air from the nose toward the larynx and food from the mouth toward the esophagus. The pharynx is what your doctor can see through your mouth when examining your throat.
The pharynx (Greek pharynx = throat; pharanx = gulf, chasm) is a cavity within the throat that serves as an air and food passage. The other main part of the throat is the larynx.
When food or fluid enters the pharynx, muscle contraction — swallowing reflex — pushes it toward the esophagus. Disorders of swallowing — dysphagia — can be caused by dry mucous membrane, dry food, disorders in the pharyngeal wall, psychological reasons or neurological disorders.
Touching of the soft palate or the back wall of the pharynx with the finger can trigger vomiting reflex.
Pharynx carries air from the nose and mouth toward the larynx. Inflamed adenoids or tonsils, sudden swelling from an insect bite or allergic reaction, stuck food or detached dentures, or injury of the pharynx can all impede breathing.
Pharynx, together with the larynx, tongue and soft palate, helps to form sounds.
The pharynx is connected with the middle ear on both sides with Eustachian tubes (Picture 1). These enable equilibration of pressure differences between the throat and the middle ear built during quick changes of altitude, diving or in disorders of the middle ear.
Tonsils and (in children) adenoids (Picture 1) can catch some microbes and foreign particles thus preventing them to enter the lungs.
Pharynx is a vertical tube lying behind the nasal and oral cavity. Its walls are built from striated (voluntary) muscles, covered by mucosal layer on its inner side.
The part of the pharynx lying behind the nasal cavity is called the nasopharynx (Lat. nasus = nose). In children, a mass of lymphatic tissue — the pharyngeal tonsil or adenoids — is protruding into the nasopharynx from its roof. Above the pharynx roof, the sphenoidal sinus — one of the paranasal sinuses — is located.
The part of the pharynx seen through the mouth is called the oropharynx (Lat. os, or- = mouth). The lingula is hanging down from its frontal edge. There is one tonsil located on each side. Normal tonsils can be small and not visible or quite prominent when checked in a mirror (Picture 2). Symmetrically enlarged and reddened tonsils are seen in acute inflammation; in chronic inflammation, tonsils can be shrunk. From asymmetric tonsils or lingula pharyngeal a pharyngeal cancer can be suspected.

The bottom part of the pharynx, lying behind the larynx is called the laryngopharynx. The back part of the pharynx continues downward into the esophagus, and its front part into the larynx. During swallowing, the entrance of the larynx is covered by a muscular fold – epiglottis.
The larynx (from Gk. larynx = the upper windpipe) is an air passage carrying air from the pharynx to the trachea (Picture 1). It contains the vocal cords (folds), also called the voice box. The adjective form of larynx is laryngeal , for example, laryngeal cancer.
Larynx is a short (1.5 inch) tube lying in the front middle part of the neck, between the pharynx above and the trachea below. It extends from the upper edge of the thyroid cartilage (laryngeal prominence – Adam’s apple) to the bottom edge of the cricoid cartilage. In skinny persons, both cartilages can be felt by fingers. The thyroid cartilage is connected to the hyoid bone by muscles. Larynx lies on the C3-C6 level of the cervical spine.
Behind the larynx, there is a lower part of the pharynx and the neck part of the esophagus.
The skeleton of the larynx consists of five main cartilages, connected by connective tissue membranes and muscles:

A thyrocricoid membrane connects the thyroid and cricoid cartilage. A cleft can be made into this membrane to enable breathing in emergency situations, when foreign objects or swelling of epiglottis from severe infection or allergic reaction obstructs the entrance of the larynx. A pocket knife can be used to make a cleft through the skin and membrane, and a thin tube, like the chase of a biro pencil, should be put into the cleft to maintain air flow.
All laryngeal muscles are voluntary striated muscles. They are innervated by a left and right Superior laryngeal nerve and Recurrent laryngeal nerve (branches of the Vagus nerve- 10th cranial nerve). These nerves also enable sensations in the larynx mucosa.
Intrinsic (internal) laryngeal muscles alter the position, tension and shape of the vocal cords. They keep vocal cords apart during breathing and together during speaking (Picture 3).
Picture 4: Vocal cords are held apart during breathing (left), and together during speaking (right) (source: Wikipedia)
Extrinsic (external) laryngeal musclesattach the larynx to the hyoid bone and other neck and head structures, and enable larynx elevation during swallowing and speaking (1).
Your primary doctor can examine your larynx with the help of a small mirror held on the back of your throat (Picture 4). Your doctor for ear, nose and throat (ENT) can use laryngoscope to make a detailed investigation of the larynx and take samples (biopsy) of laryngeal mucosa. Histological changes of a sample can be then checked under the microscope. CT or MRI can be use to detect disorders in the laryngeal wall or adjacent structures.

Main disorders of the larynx include:
Hoarseness can be caused by any of above disorders.
