Question

question 9
1 pts
the trachea, bronchial tree, and lungs make up the
upper respiratory tract.
lower respiratory tract.
cell respiration.
none of the above.
question 10
1 pts
the air - containing spaces that open, or drain, into the nasal cavity are called
nasal mucosa.
turbinates.
conchae.
paranasal sinuses.
question 11
1 pts
the microscopic cilia function to
filter air.
move air to the lungs.
move air to the pharynx.
move mucus toward the pharynx.

Explanation:

• Question 9: The trachea, bronchial tree, and lungs are part of the lower respiratory tract. The upper respiratory tract includes structures like the nose, nasal cavity, and pharynx. Cell respiration is a cellular process, not an anatomical structure.
• Question 10: Paranasal sinuses are air - containing spaces that open into the nasal cavity. Nasal mucosa is the lining of the nasal cavity. Turbinates (also known as conchae) are bony structures in the nasal cavity, not air - containing spaces that drain into it.
• Question 11: Microscopic cilia in the respiratory tract move mucus toward the pharynx. They do not directly filter air (that is more of a function of larger structures like nasal hairs in part), and they do not move air (air movement is mainly due to pressure differences in breathing).

Answer:

• Question 9: lower respiratory tract.
• Question 10: paranasal sinuses.
• Question 11: move mucus toward the pharynx.
