The left and right lungs are slightly different in size and shape due to the heart pointing to the left side of the body. c. decreased carbon dioxide levels in the blood The trachea, or windpipe, is a 5-inch long tube made of C-shaped hyaline cartilage rings lined with pseudostratified ciliated columnar epithelium. 448, Normal, quiet breathing which moves approximately 500 mL of air per breath e. primary bronchus Larynx: cartilaginous tube; surrounds/ protects glottis (voice box); three large cartilages (epiglottis, thyroid cartilage, cricoid cartilage) a. Epiglottis: projects superior to glottis; forms lid over it i. The Larynx and Vocal Cords Allow Us to Breathe and Talk and Sing The larynx connects the lower part of the pharynx, the laryngopharynx, to the trachea. 445, Which inspiratory muscles contract so we can inspire air? The larynx is at the superior (or cephalad) end of the trachea and is located just below the epiglottis and glottic opening.
