Answer 11

terminal bronchioles

Question 12

protective coverings of the lungs..

Answer 12

visceral pleura

Question 13

smooth muscle that decreases the diameter of the trachea/ durng coughing and sneezing this action helps to expel irritants from the trachea

Answer 13

Trachealis

Question 14

No gas exchange occurs, consists of Trachea, bronchi, bronchioles ;
supportive connective tissue changes(cartilage rings are replaced), epithelium changes, smooth muscle becomes more important

Answer 14

Conducting zone

Question 15

site of gas exchange consist of respiratory bronchioles, and Alveoli,

Answer 15

Respiratory zone

Question 16

fluid containing a fluid like substance , that reduces surface tension within the alveoli; if not inner walls of an alveolus would stick together during exhalation

Answer 16

surfactant

Question 17

Most important triangular shaped paired cartilage; anchor the vocal chords

Answer 17

Arytenoid Cartilages
