    brainstem to the respiratory muscles
  29. Abdominal muscle group that functions as an accessaroy muscle of ventilation
  30. The exchange of gases between blood and tissues
  31. The 3 parts of the pharynx is also called this
  32. Lies below the hypopharynx and is formed by a complex arrangement of
    nine cartilages and numerous muscles and it functions to protect the
    respiratory tract during eating, drinking and phonation.
  33. Major divisions of the lungs; the right lung has three lobes and the left lung has two lobes
  34. Upper triangular portion of the sternum
  35. Portion of the thoracic cavity lying in the middle of the thorax(between
    the two pleural cavities.) It extends from the vertebral column to the
    sternum and contains the trachea, esophagus, heart and great vessels of
    the circulatory system
  36. The stoking action of millions of cilia propels the surround mucus at a speed of about 2 cm per minute
  37. Upper portion of the airway behind the nasal and oral cavities
  38. Boney plate that separates the nasal cavity from the oral cavity
  39. Thin membrane covering the surface of the chest wall, mediastinum, and
    diaphragm that is continuous with the visceral pleura around the lung
  40. The region where the nasal and oral cavities open into
  41. Paired nerves that originate as branches of spinal nerves C3-5, pass
    down along the mediastinum, and innervate the diaphragm: carry nervous
    signals from the brainstem to the respiratory muscles
  42. Openings between the adjacent alveoli
  43. A single terminal bronchiole that supplies a cluster of respiratory bronchioles. Also referred to as the acinus
  44. Of or pertaining to the epithelial cell type that appears to be
    organized in layers, but in which each cell actually contacts the
    basement membrane
  45. Detergent-like substance secreted into the alveoli that reduces surface tension and stabilizes alveoli
  46. A group of abdominal muscles that contributing to inspiration by contracting at end-exhalation.
  47. Referring to the three muscles arising from the cervical vertebrae,
    inserting into the first and second ribs, accessory muscles of
  48. Minor divisions of the lung; each segment is associated with a major branch of the airway
  49. Posterior portion of the anterior roof of the oral cavity
  50. The fused connection between the manubrium and the body
  51. Originate from the manubrium and clavicle and insert on the mastoid process of the temporal bone
  52. Elongated flattened bone forming the middle portion of the anterior thorax
  53. Located above the sternum , this is the superior edge of the manubrium
    which forms a shallow depression called a notch. Also known as jugular
