The pharynx is opened or closed by two mechanisms: (1) Contractions of the cricothyroid and of the intrinsic muscles of the larynx open and close the vocal cords. This ligament is enclosed by a fold of mucous membrane to form the vestibular fold (false vocal cord) which extends from the thyroid cartilage to the arytenoid cartilage. D) larynx pg. The smaller external laryngeal nerve provides motor innervation to the cricothyroid muscle. It forms the anterior and lateral portions of the larynx and has no posterior component. 1200 mL b. the nasal conchae Continued From Above act as the functional units of the respiratory system by passing oxygen into the body and carbon dioxide out of the body. H) main (primary) bronchus The larynx, also known as the voice box, is a short section of the airway that connects the laryngopharynx and the trachea. 449, According to the laws of diffusion, movement of a respiratory gas occurs toward the area of higher concentration of that particular respiratory gas.

The larynx is sometimes included in both the upper and lower airways. A Longitudinal wave is a wave in which the particles of the medium Vibrate to the direction of the motion of the waves, science pre- assessment choose the letter of the correct answer 1.when is an object considered to be in motion 1.when its position changes with respec 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. What part of the respiratory system routes air and food into their proper channels and plays a role in speech? pg.439, Directs food posteriorly into the esophagus. The internal intercostal muscles are the deeper set of muscles and depress the ribs to compress the thoracic cavity and force air to be exhaled from the lungs. The superior laryngeal nerve divides into two branches: internal (sensory) and external (motor). The larynx is a tough, flexible segment of the respiratory tract connecting the pharynx to the trachea in the neck.

The nose is a structure of the face made of cartilage, bone, muscle, and skin that supports and protects the anterior portion of the nasal cavity. 449, Wheezing is a whistling sound associated with diseased respiratory tissue, mucus, or pus. When the partial pressure of carbon dioxide is high in the tissues, the enzyme carbonic anhydrase catalyzes a reaction between carbon dioxide and water to form carbonic acid. B) interferon Air inhaled through the oral cavity enters the pharynx at the oropharynx. C) kinin The anterior portion of the palate that is supported by bone is called the ___.

Its free lower edge is thickened and forms the vestibular ligament. H) main (primary) bronchus Finally, the millions of tiny terminal bronchioles conduct air to the alveoli of the lungs. Glottis is medical terminology for the opening of larynx into the airway. D) inspiratory reserve volume Input Validation:__ Do not accept a negative value for the number of checks written. The primary bronchi contain many C-shaped cartilage rings that firmly hold the airway open and give the bronchi a cross-sectional shape like a flattened circle or a letter D. As the bronchi branch into secondary and tertiary bronchi, the cartilage becomes more widely spaced and more smooth muscle and elastin protein is found in the walls. A) bronchioles The net result of external respiration is the movement of oxygen from the air into the blood and the movement of carbon dioxide from the blood into the air. G) epiglottis
