👉 Trachea, also known as bronchus, is a tube-like organ that connects the lungs to the trachea. It helps in breathing by allowing air to pass through the trachea before it enters the lungs. The trachea contains two main tubes - the larynx and the pharynx. The larynx is the part of the throat where we make sounds, while the pharynx is the part that filters out food and liquids from the stomach.
