The highlighted cartilage is the largest of the cartilage pieces that make up the larynx. These bronchi are also lined by pseudostratified ciliated columnar epithelium containing mucus-producing goblet cells (Figure 22.1.8b). The major entrance and exit for the respiratory system is through the nose. The act of swallowing causes the pharynx and larynx to lift upward, allowing the pharynx to expand and the epiglottis of the larynx to swing downward, closing the opening to the trachea. The Lymphatic and Immune System, Chapter 26. The inner edges of the true vocal cords are free, allowing oscillation to produce sound. Available from: http://erj.ersjournals.com/gca?submit=Go&gca=erj%3B37%2F5%2F1037&allch=. Both the uvula and soft palate move like a pendulum during swallowing, swinging upward to close off the nasopharynx to prevent ingested materials from entering the nasal cavity. The 8 Major Systems Some of these glands produce up to 2 secretions (Hormones) but mostly each gland will have the task of producing one. Do the diaphragm increase or decrease diameter of the thoracic cavity? of air inhaled & exhaled during 1 normal breath, max amt. The nasopharynx is flanked by the conchae of the nasal cavity, and it serves only as an airway. The cilia beat the mucus upward towards the laryngopharynx, where it can be swallowed down the esophagus.
