the anatomical division of the pharynx that is located behind the mouth from the soft palate above to the level of the hyoid bone below is called the:
nasopharynx.

sphenopharynx.
question 5
1 pts
the upper respiratory tract includes all of the following structures except the:
larynx.
trachea.
oropharynx.
nasopharynx.

Explanation:

• Question 3: The respiratory system is anatomically divided into the upper respiratory tract (nose, pharynx, etc.) and the lower respiratory tract (larynx, trachea, bronchi, lungs). "Air distribution and gas exchange" are functions, not anatomical divisions. Trachea is part of the lower respiratory tract, and lungs are the main organs of gas exchange. "Cranial and thoracic" are related to body cavities, not respiratory system divisions.
• Question 4: The oropharynx is located behind the mouth, from the soft palate above to the level of the hyoid bone below. The nasopharynx is behind the nasal cavity, the laryngopharynx is below the oropharynx near the larynx, and sphenopharynx is not a standard anatomical term.
• Question 5: The upper respiratory tract includes the nose, nasal cavity, pharynx (nasopharynx, oropharynx). The larynx is a transitional structure (some classify it as upper, but more accurately it can be a transition). The trachea is part of the lower respiratory tract as it leads to the lungs for gas exchange.

Answer:

• Question 3: Upper respiratory tract and lower respiratory tract
• Question 4: oropharynx
• Question 5: trachea
