As the throat labeled diagram suggests, the important parts of a human throat consist of a muscular tube that runs from the back of the nose down into the human body's neck. The throat consists of three major sections, the nasopharynx, oropharynx, and laryngopharynx (also known as hypopharynx). As we see here, the esophagus is the tube that carries food and liquids from the throat to the stomach, the trachea is the tube that carries air between the throat and the lungs, and the lymph nodes are bean-shaped organs that help the body fight infections related to sinus.
