What is a pharynx and what is its function?
Pharynx is the part of the throat that is common to both digestive system andrespiratory system. It starts behind the nose and ends in the beginning of the voice box (larynx) and the oesophagus. It is a muscular tube lined by mucous membranes that connects the nose with the wind-pipe (trachea) and the mouth with the food-pipe (esophagus) and thus acts as a common passage for both food and air. Structure of Pharynx: Pharynx is a soft collapsible tube. It is about 13 cm long in humans and lies in the front of the spinal column. The pharynx contains tonsils and adenoids (in children). Pharynx is divided into three parts namely the oropharynx, nasopharynx and laryngopharynx. Functions of Pharynx: The main function of pharynx is to act as a common passage for both food and air. Thus the pharynx should channel food without choking. Pharynx plays a major role in the first phase of swallowing. As the food bolus is pushed by the tongue into the pharynx, it pushes the food down by muscular contraction down the esophagus. The other important function of Pharynx is to equalize pressure that gets built near the ear drums. This is made possible by the two eustachian tubes (one from each ear) that connect the middle ear with pharynx. Pharynx is very soft and can be easily collapsed. Thus any physical structure can cause an obstruction in the pharynx. Pharynx is easily susceptible to infections. The inflammation or infection of pharynx is known as pharyngitis which is caused by micro organisms that enter through nose or mouth. The pharynx might collapse during sleep and the resulting condition is known as Obstructive Sleep Apnea (OSA). Any failure in the normal functioning of pharynx can cause breathing, swallowing or voice problems.
What is tha function of the pharynx?
It has both respiratory and digestive functions, serving as a common passageway for air, food and drink.The mouth leads into the oropharynx. The mucous lining the walls of the oropharynx change slightly to adapt for handling food as well as air. It is here that the two tonsils are located. One is at the entrance from the mouth into the oropharynx, and the other is somewhat deeper.

What is the order of organs that air passes when you breathe in?
In the human respiratory system, air goes through the mouth/oral cavity, down the throat/pharynx, glottis, trachea, one of the two bronchi that leads into a lung, further divides into bronchioles, and at last ends in the alveoli. Here, air stops in the lungs, loses oxygen to capillaries, gains carbon dioxide, and returns to the atmosphere via the same path.
