What protects the superior opening of the larynx? 440, Each main (primary) bronchus enters the lung at the apex. Surrounding the lungs are sets of muscles that are able to cause air to be inhaled or exhaled from the lungs. a. bicarbonate ion The larynx, also known as the voice box, is a short section of the airway that connects the laryngopharynx and the trachea. The pressure gradient is now reversed, resulting in the exhalation of air until the pressures inside the lungs and outside of the body are equal. The mouth, also known as the oral cavity, is the secondary external opening for the respiratory tract. What is the flap of elastic cartilage that protects food from entering Which tissue forms the C-shaped rings that reinforce the trachea?

Your larynx is a hollow tube that connects your throat (pharynx) to the rest of your respiratory system. a. internal respiration a. the diaphragm and intercostal muscles contract E) pulmonary ventilation, Expiration (exhalation) occurs when: The vocal apparatus of the larynx is called the glottis and consists of two vocal folds (true vocal cords) and the rima glottidis. Because the pathway of air entering the body from the mouth is shorter than the pathway for air entering from the nose, the mouth does not warm and moisturize the air entering the lungs as well as the nose performs this function. It extends from the epiglottis (namely the glossoepiglottic and pharyngoepiglottic folds) to the inferior aspect of the cricoid cartilage. Under normal resting conditions, the body maintains a quiet breathing rate and depth called eupnea. pg. vocal folds (true vocal cords) When breathing in, air enters the larynx through an opening called the_____. b. false d. the right lung has three lobes d. deoxygemoglobin The smaller external laryngeal nerve provides motor innervation to the cricothyroid muscle. pg. c. palatopharynx C) expiratory reserve volume c. trapezius; latissimus dorsi C) glottis Serves as attachment points for several muscles. e. epiglottis Lingual tonsil. The posterior margin of each lamina extends upward into a superior horn and downward into an inferior horn. It has a flap of skin at the top, called the epiglottis.
