The larynx, commonly known as the voice box, is a crucial part of the respiratory system where the vocal cords reside, responsible for sound production. Situated between the pharynx and the trachea, this tube-like organ measures about two inches in length and is located in the neck. We engage the larynx in activities such as breathing, speaking, and swallowing. Its outer structure forms the prominent area at the front of the neck, often called the "Adam's apple." Inside the larynx, the vocal cords, two muscle bands shaped like a "V," play a vital role. When we inhale, air travels through the nose or mouth, passes through the larynx, down the trachea, and into the lungs. During exhalation, this process reverses. While breathing, the vocal cords remain relaxed, allowing air to pass through quietly. However, when we speak, the vocal cords pull together and tighten. Air expelled from the lungs forces its way between them, causing vibrations that produce sound. The tongue, lips, and teeth then shape these sounds into words. Positioned just behind the trachea and larynx is the esophagus, the tube that directs food from the mouth to the stomach. In the throat, the openings of the esophagus and the larynx lie in close proximity. To prevent food from entering the windpipe during swallowing, a flap known as the epiglottis covers the larynx.
