The bronchi and bronchioles also use the mucus and cilia of their epithelial lining to trap and move dust and other contaminants away from the lungs. The mouth, also known as the oral cavity, is the secondary external opening for the respiratory tract. The inferior horn bears a facet on its medial surface with which its articulates with the posterolateral surface of the cricoid cartilage to form the cricothyroid joint. Tidal The presence of smooth muscles and elastin allow the smaller bronchi and bronchioles to be more flexible and contractile.

Inferior to the epiglottis is the thyroid cartilage, which is often referred to as the Adams apple as it is most commonly enlarged and visible in adult males. The nasopharynx is the superior region of the pharynx found in the posterior of the nasal cavity. pg. Eupnea is maintained until the bodys demand for oxygen and production of carbon dioxide rises due to greater exertion. Air exiting the body through the nose returns moisture and heat to the nasal cavity before being exhaled into the environment. The larynx is a tough, flexible segment of the respiratory tract connecting the pharynx to the trachea in the neck. Each saccule is lined with mucus glands that produce mucus to lubricate the vocal folds.

The epiglottis is a flap of elastic cartilage that acts as a switch between the trachea and the esophagus. D) larynx Pulmonary ventilation is the process of moving air into and out of the lungs to facilitate gas exchange. The vocal apparatus of the larynx is called the glottis and consists of two vocal folds (true vocal cords) and the rima glottidis. The epiglottis is one of the cartilage pieces of the larynx and serves as the cover of the larynx during swallowing. Each superior laryngeal nerve divides into the internal and external laryngeal nerves. When breathing in, air enters the larynx through an opening called the _________. This gives your doctor information 1. The main function of the trachea is to provide a clear airway for air to enter and exit the lungs. Inferior to the thyroid cartilage is the ring-shaped cricoid cartilage which holds the larynx open and supports its posterior end. C) expiratory reserve volume c. dyspnea The larynx is a cartilaginous segment of the respiratory tract located in the anterior aspect of the neck. c. frequent pulmonary infections are common Let a = 1 and b = 0 to obtain a special case of the Cauchy distribution with density, f(x)=111+x2
