Respiratory Digestive systems

Respiratory, Digestive, Clinicals
Show Answers:

  1. The _______ system is responsible for gas
    • Respiratory
    • System
  2. The respiratory tract is divided into ________
    & ________ respiratory tracts:
    • Upper
    • & Lower
  3. The upper respiratory tract consists of what?
    • Nose
    • and Pharynx
  4. The lower respiratory tract consists of what?
    Deals with actual gas exchange
  5. Name 3 of the 5 functions of the respiratory
    • Gas
    • exchange; regulation of blood pH, Voice production (vocalization); Protection
    • from air-borne hazards: pathogens and irritants; Olfaction
  6. What is the downside of the respiratory system
    • Body
    • must compensate for significant heat and water loss associated with breathing
  7. The conducting division is lined by what
    • Respiratory epithelium;
    • respiratory mucosa
  8. • Respiratory epithelium contains what?
    • Goblet
    • Cells (Secrete mucus containing IgA), serous glands (secrete a watery solution
    • containing lysozymes that underlays the mucus) and an abundant vascular supply
    • (blood supplies both the heat for warming and the water for moistening)
  9. Goblet cells secrete what?
    • Mucus
    • (containing IgA)
  10. What is the external part of the nasal cavity?
  11. What makes up the posterior nose?
    Nasal Bones
  12. This divides the nasal cavity into right and
    Nasal Septum
  13. Most of the septum is made up of what bone:
    • Perpendicular
    • plate of the ethmoid
  14. This plate of the ethmoid separates the nasal
    cavity from the cranial (brain) cavity & has holes (foramina) for the
    passage of the olfactory nerves back into the brain:
    • Cribriform
    • Plate
  15. This type of epithelium is found where olfactory
    receptors are found:
    • Olfactory Epithelium (olfactory
    • mucosa)
  16. T/F Olfactory
    chemoreceptors are not renewable neurons
  17. The floor of the nasal cavity is called the
  18. The anterior part of the palate is what?
    Hard Palate (Bony)
  19. The posterior part of the palate is what?
    Soft Palate ( Skeletal Muscle)
  20. Failure of the shelves of tissue that form the
    palate to fuse in the midline causes what?
    • Cleft
    • Palate
  21. opening of the nostrils is also called what?
  22. These hairs, at the nares (opening of the
    nostrils) prevent large particles and insects from entering the nose:
  23. Three pairs of ridges create more air turbulence
    (causing more collisions between the air and the mucosa) and are called what?
  24. This duct drains tears, which iswhy your nose
    runes when you cry
    • Nasolacrimal
    • Ducts
  25. How many pairs of paranasal or nasal sinuses are
    there & name them all:
    Four;Frontal, sphenoid, ethmoid, and maxilla
  26. This begins at the back of the nasal cavity and
    the back of the mouth:
    Pharynx or throat
  27. There are three sections of the pharynx, what
    are they?
    • Nasopharynx, Oropharynx, and
    • Laryngopharynx
  28. T/F
    The parts of the pharynx that conduct both air and food/liquids do not have
    ciliated respiratory mucosa (Passing
    food would damage the cilia)
