these cartilages hold the trachea rigidly open at the same diameter all the time

Question

these cartilages hold the trachea rigidly open at the same diameter all the time they form a solid cartilaginous tube e, they open to permit passage of nerves that innervate laryngeal muscles d. to permmit the e. none of the above 1. What is the significance of the C shaped or open cartilaginous rings gus to transiently bulge anteriorly into the tracheal lumen and for changing tube diameter 2. During a val salva maneuver (foreing air against a closed glottis- as demonstrated in class) and during exhalation, the pressure inside the lungs is a. less than the pressure in the atmosphere b. greater than the pressure in the atmosphere e. equal to atmospherie pressure d. greater than intra-alveolar pressure e. none of the above 3. If you break a rib that damag ges causes a pleural decompression during CPR, which was more likely to be damaged parietal pleura visceral pleura 4. Asthma typically disrupts ventilation/mechanical processes b. disrupts respiratory processes 5. The respiratory filtering mechanism a. includes cilia which occur throughout the entire system except in the nasal cavity b. removes virtually all particles larger than approximately 10 um from inspired air c. traps particles with mucus as well as cilia only operate when the air conditions are particularly dirty b and c 6. A chronic progressive condition characterized by shortness of breath and resulting from the destruction of respiratory exchange surfaces a. pneumothorax b. pneumonia asthma 7. Asthmatics often need to open their air passages via sympathetic stimulation. This is called abronchodilation vascodilation c. bronchoconstriction d. vascocontriction 8. The following is a list of some airways. What is the order in which air passes through them? 1. lobar bronchus 2. bronchioles 3. alveolar ducts 4. primary bronchus 5. respiratory bronchiole 6. alveoli 7. terminal bronchiole

Explanation / Answer

1- (a) these cartilage hold the trachea rightly open at same diameter all the time

2- ( c) equal to atmosphere pressure

3-( a) parietal pleura

4-( a) affecte ventilation mechanism

5-(e) option b and c

6- (d) emphysema

7-(a) bronchodilation

8-(a) as given in option a

9-(c) hypoxia

10-(a) they both are equal

11-(d) apnea

12-(b) renal hypoxia

Hope u understand the answer tha thank u
