Brush Cells

Answer 6

gas or fluid exchange

Respiratory Tract Sequence of Lower Respiratory

Answer 17

Larynx→Trachea→Bronchi→Bronchiles→Alveoli→Capillaries of lungs

Question 18

What is the purpose of the epiglottis?

Answer 18

reroutes food away from the respiratory system and toward the digestive system

Answer 31

Vestibular folds

Question 32

What are vocal folds?

Answer 32

lower covered in nonkeratinized stratified squamous epithelium to handle wear and tear of use

Question 33

Answer 36

Type II

Question 37

What is the purpose of surfactant?

Answer 37

prevents respiratory collapse through lowering surface tension
