The larynx is located within the anterior aspect of the neck, anterior to the inferior portion of the pharynx and superior to the trachea. Its primary function is to protect the lower airway by closing abruptly upon mechanical stimulation, thereby haltin
What is the Function of the Larynx? The larynx is a pliable tube that is a part of the upper respiratory system that allows air to move from the pharynx, which is found towards the back of the nose, down through the trachea, or what some may know as the windpipe. Though small, it ...
