Week 6: Chapter 23 Assessment CU
Some structures in both the upper and lower respiratory tracts serve as sites for gas diffusion. -
ANS False
Place the layers of the trachea in order from superficial to deep. - ANS adventitia, hyaline
cartilage, submucosa, mucosa
A mechanical ventilator may aid directly in - ANS pulmonary ventilation.
Decreased surfactant will affect alveolar surface tension to cause decreased pulmonary
ventilation, but will have no effect on lung compliance. - ANS False
If you were to take 10 breaths/min and inhaled about 600 mL/breath, your minute ventilation
rate would be - ANS 6 L/min.
Attached and directly affected by some of the nine cartilages associated with the larynx are two
bands of elastic ligaments which form what are known as _____ and allow us to speak. - ANS
vocal folds (true vocal cords)
The trachea, bronchi, bronchioles and terminal bronchioles combine to form what is often
referred to as the bronchial tree. What is its function? - ANS It is the conduction zone of the
lower respiratory tract providing a conduit for gases to travel to the alveoli.
Which of the following are part of the respiratory system? Select all that apply. - ANS nose
pharynx
trachea
lungs
Gas exchange occurs in the conducting zone. - ANS false
Which of the following statements is INCORRECT? - ANS The trachea is located posterior to
the esophagus and extends from the larynx to the superior border of the fifth thoracic vertebra.
Which of the following statements is correct? - ANS All of these statements are correct.
Lung capacities are sum of two or more lung volumes. - ANS True
The point where the trachea divides into right and left primary bronchi is a ridge called - ANS
Carina
