Theyve been in business since the 1940s, and today they own about 30% of the U.S. laundry detergent market. b. respiratory gas transport pg. The laryngeal cavity is divided into three regions: The lateral walls of the middle part of the laryngeal cavity bulge outward to form lateral recesses (laryngeal ventricle) between the vestibular fold and the vocal fold. Superior to this prominence is the superior thyroid notch. Play a major role in speech production B. E) erythema, Where are the respiratory centers housed which control involuntary breathing rates: Inferior to the epiglottis is the thyroid cartilage, which is often referred to as the Adam's apple as it is most commonly enlarged and visible in adult males. Capillary blood has a higher partial pressure of oxygen and a lower partial pressure of carbon dioxide than the tissues through which it passes. When greater volumes of air are required by the body, such as during exercise, the smooth muscle relaxes to dilate the bronchi and bronchioles. The net result of internal respiration is the diffusion of oxygen into the tissues and the diffusion of carbon dioxide into the blood. The respiratory rate in adults is: Forms the vertical, central axis of the body and includes all bones in head, neck, check, and back. It is quite mobile in the neck and can be seen and felt moving upward and forward during swallowing, closing off the trachea and opening the esophagus.

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. a. increased oxygen level in the blood b. emphysema b. The trachea connects the larynx to the bronchi and allows air to pass through the neck and into the thorax. 438, What role do the tonsils play in the respiratory system? Cilia on the surface of the epithelial cells move the mucus superiorly toward the pharynx where it can be swallowed and digested in the gastrointestinal tract. In addition, it protects the respiratory tract by warming and moistening the air and propelling foreign particles upwards towards the pharynx for expulsion. Epiglottis protects food from passing via the glottis to the trachea and bronchus etc. D) internal respiration pg. b. inspiration pg.

Superior to this prominence is the superior thyroid notch. 448, Amount of air that can be inhaled forcibly over the tidal volume. 443, Which zone includes the respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli and is where gas exchange occurs? It consists of a cartilaginous skeleton connected by membranes, ligaments and associated muscles that suspend it from surrounding structures. d. alveolar ducts Protects the superior opening of the larynx during swallowing. a. true And its recorded in the Gospels. b. air moves into the lungs e. the fused basement membranes of alveolar and pulmonary capillary walls of ethmoid bone. B) dead space volume d. inspiration G) epiglottis D) COPD H) main (primary) bronchus This larynx is comprised of nine cartilages. Because the pharynx is also used to swallow food, the epiglottis ensures that air passes into the trachea by covering the opening to the esophagus. What is the meaning of an Organisational procedure relating to debriefing? The nose and nasal cavity form the main external opening for the respiratory system and are the first section of the body's airwaythe respiratory tract through which air moves. The epiglottis is a flap of elastic cartilage that acts as a switch between the trachea and the esophagus. e. inability to produce mucus Epiglottis, protects the superior opening of the larynx and where food enters instead of going to larynx What happens when we swallow food? a. splanchnic; sacral b. false 447, Which of the following events of respiration involves the flow of air out of the lungs?

The secondary bronchi carry air into the lobes of the lungs2 in the left lung and 3 in the right lung. pg. c. alveolar sacs This board fibroelastic sheet has a thick median region called the median thyrohyoid ligament as well as lateral parts called the lateral thyrohyoid ligaments, which directly attach to the superior horn. During inspiration, the inspired air enters through the nose or mouth, travels through the pharynx to the larynx, passes through the glottis and into the trachea. a. internal respiration Vocal cords or voice box, which is located at the top of the .
