This human anatomy ClipArt gallery offers 73 illustrations of the human upper respiratory system, including organs involved in respiration. The human upper respiratory tract includes the nasal passages, pharynx, and the larynx.

Operative approaches through the front of the neck to the larynx, pharynx, and trachea. a: Approach to pharynx between the hyoid and the thyroid cartilages. b: Approach to the larynx between the thyroid and cricoid cartilages. c: approach to the larynx below the cricoid cartilage and above the isthmus of the thyroid gland. d: Approach for low tracheotomy.

Three laryngoscopic view of the superior aperture of the larynx and surrounding parts. Labels: A, the glottis during the emission of a high note in singing; B, in easy and quite inhalation of air; C, in the state of widest possible dilation, as in inhaling a very deep breath. The diagrams A', B', and C', show in horizontal sections of the glottis in position of the vocal ligaments and arytenoid cartilages in the three several states represented in the other figures. In all the figures, so far as marked, the letters indicate the parts as follows, viz. : l, the base of the tongue; e, the upper free part of the epiglottis; e', the tubercle or cushion of the epiglottis; p h, part of the anterior all of the pharynx behind the larynx; in the margin of the aryteno-epiglottisdean fold w, the swelling of the membrane caused by the cartilages of Wrisberg; s. that of the cartilages of Santorini: a, the tip or summit of the arytenoid cartilages; c v, the true vocal cords r lips of the rima glottidis; c v s, the superior or false vocal cords; between them the ventricle of the larynx; in C, tr, is placed on the anterior wall of the receding trachea, and b indicated the commencement of the two bronchi beyond the bifurcation which may be brought into view in this state of extreme dilation.
