Answer Details
The upper part of the trachea in mammals is called the "larynx." It's a small structure located at the top of the trachea, where it meets the back of the throat. The larynx helps to protect the airway during swallowing by closing off the opening to the trachea with a flap called the epiglottis. It also plays an important role in producing sound, as it contains the vocal cords.
