  Pulmonary valve

  
• What valve is labeled 4?

  tricuspid valve

  
• What structure is labeled 5?

  atrial septum

  
• What is this structure?

  chordae tendineae (heartstrings)

  
• Which ventricle of the heart is thicker?

  left ventricle
• What structure is this?

  base

  
• What are the 3 major circuits?

  systemic, coronary, pulmonary
• Circuit where arteries deliver oxygenated blood to capillary beds within body tissues and return deoxygenated blood back to heart via veins

  systemic
• Circuit similar to systemic but it is limited to heart wall

  Coronary
• Circuit where arteries deliver deoxygenated blood to capillary beds in LUNGS, and veins return oxygenated blood to heart

  Pulmonary
• The arteries in the brain circle to create what?

  Circle of Willis
• What is the largest vein in the human body?

  Great saphenous vein
• What vein is blood drawn from in the medical field?

  Medial cubital veins
• Vein on medial side of arm

  Basilic vein
• Which lung has 3 lobes (superior, middle, inferior), oblique and horizontal fissures, and hilum?

  Right lung
• Which lung has 2 lobes (superior and inferior) oblique fissure, cardiac notch, and hilum?

  Left lung
• What contains the nares, vestibule, nasal septum, superior nasal conchae, middle nasal conchae, and inferior nasal conchae?

  Nasal cavity
• The sphenoid, ethmoid, frontal, and maxillary are all

  Paranasal sinuses
• Compromises the anterior two-thirds of the palate; separates the oral cavity from the nasal and sinus cavities

  hard palate
• Makes up the posterior third of the palate and is a posterior continuation of the hard palate; elevates the nasopharynx

  Soft palate
• Structure who’s primary function is to secrete saliva to moisten your mouth and throat

  Uvula
• Contains nasopharynx, oropharynx, laryngopharynx, and the opening for Eustachian tubes

  Pharynx
• Voice box

  Larynx
• Lymph nodes at the top of the mouth and the bottom of the throat

  Tonsils
• The airway that leads from the larynx to the bronchi

  Trachea
• Includes nose, nasal cavity, and pharynx

  Upper respiratory
• Includes larynx, trachea, bronchi, bronchioles, alveolar ducts, and alveoli


  Lower respiratory
• Passageway that transports air

  Conducting zone
• Gas exchange

  Respiratory zone
• Movement of respiratory gases between atmosphere and alveoli

  Pulmonary ventilation
• Exchange of gas between alveoli and blood (external respiration)

  Alveolar gas exchange
• Moving gases in blood

  Gas transport
• Exchange between blood and systemic cells (tissue); external respiration

  System gas exchange
