Trachea are generally highly elastic but they may calcify with age. The trachealis muscle connects the ends of the incomplete rings and contracts during coughing, reducing the size of the lumen of the trachea to increase the rate of air flow. The esophagus lies posteriorly to the trachea, adjoining along the tracheoesophageal stripe. Circular horizontal bands of fibrous tissue called the annular ligaments of trachea join the tracheal rings together. The cartilaginous rings are incomplete to allow the trachea to collapse slightly so that food can pass down the esophagus. A flap-like epiglottis closes the opening to the larynx during swallowing

Michael Treveloni of Film School Rejects noted, "The film is a not just a science-fiction horror story: it is a commentary on the importance of dialog, showcasing the need for communication in its many forms. With Geoff, "Errors" presents the perfect, damaged subject.". At the Fantastic Fest
