The pharynx (throat) is a muscular tube in the middle of your neck. It helps you to breathe and digest food. Many medical issues can affect your pharynx, from a common cold to cancer. You can protect your pharynx by not smoking and avoiding infection.

Overview

Your pharynx (throat) is in the middle of your neck. It includes (inset) your nasopharynx, oropharynx and laryngopharynx.

What is the pharynx?

Your pharynx (throat) is a multitasking muscular funnel that helps you breathe and directs food and liquid to your digestive system. You can keep your pharynx healthy by quitting smoking and protecting yourself from infections.

Function

What does the pharynx do?

In general, it supports your respiratory and digestive systems. Specifically, your pharynx:

  • Routes air coming in your nose and mouth down to your larynx (voice box), which, in turn, moves air to your trachea and lungs.
  • Delivers food and liquid to your esophagus, which sends them on to your stomach. More than that, your pharynx helps to make sure particles of food and liquid don’t tumble into your trachea and your lungs.

Anatomy

Where is the pharynx located?

Your pharynx is in the middle of your neck. It sits below the lower part of your skull and just above your esophagus and larynx.

What are the parts of your pharynx?

A pharynx has three parts:

  • Nasopharynx, at the top of your throat. It connects your nose to your respiratory system.
  • Oropharynx,in the middle of your throat. It contains your tonsils at the base of your tongue and connects to your oral cavity. Air, food and fluid all pass through your oropharynx.
  • Hypopharynx, at the bottom of your pharynx. It regulates how food moves to your esophagus and on to your digestive system, and how air moves to your lungs.

What does the pharynx look like?

Your pharynx is a tube that’s about 4 inches long. It’s mostly muscle, with some cartilage that makes up the back of your pharynx.
