Question 1

What does the diaphragm do during inhalation (inspiration - drawing air in)?

Answer 1

1. Contracts and descends

2. Enlarges the thoracic cavity and decreases the air pressure

Question 2

What does the diaphragm do during the exhalation (expiration)?

Answer 2

1. Diaphragm relaxes and elevates

2. Thoracic cavity become smaller and increases the air pressure

Question 3

1. Bronchioles
2. Alveoli
3. Lung capillaries

Question 5

What is the order of respiratory flow chart? (Flow path of air into the respiratory system).

Answer 5

Nose –>Nasal cavities and paranasal sinuses –> Pharynx –> Larynx –> Trachea –>Bronchi –> Bronchioles –> Alveoli –> Lung capillaries

Question 6

What is the parietal pleura?

Answer 6

The outer layer of membrane of the pleura

Question 7

What is the difference between pneumothorax and atelectasis?

Answer 7

1. Both involve collapse of alveoli
2. Pneumothorax is caused by separation of the visceral and parietal pleura by a volume of air
3. Atelectasis caused by by numerous mechanism but IS NOT DUE to separation of membranes

Question 8

What is the cause of atelectasis?

Answer 8

1. Obstruction of the airways

2. Accumulations of fluid, blood, or air in the pleural cavity
