|
||||
| show | capillary exchange
🗑
|
||||
| Which of the following makes up a layer of epithelial cells that overlies the wall of the alveoli? | show 🗑
|
||||
| Respiratory distress syndrome in an infant results from an inability to breathe because of excess surfactant production in the alveoli by type I cells. True/False | show 🗑
|
||||
| show | True
🗑
|
||||
| Which of the following is not part of the conducting zone in the respiratory tract? respiratory bronchioles, trachea, terminal bronchioles, primary bronchi | show 🗑
|
||||
| show | False
🗑
|
||||
| The primary force responsible for air moving into the lungs during inhalation is ________________. | show 🗑
|
||||
| show | tidal volume
🗑
|
||||
| The functional gas exchanging units are termed _______________. | show 🗑
|
||||
| The compliance of the lung increases as the lungs expand. True/False | show 🗑
|
||||
| show | low pH; high CO2
🗑
|
||||
| The amount of air that cannot be expelled is the _____________. | show 🗑
|
||||
| What structure bufurcates into the bronchi that enter the right and left lungs? | show 🗑
|
||||
| show | terminal bronchioles
🗑
|
||||
| show | propel mucus containing trapped particles toward the glottis
🗑
|
||||
| The transition from the conducting to the respiratory zone in the lungs occurs at the ______________. | show 🗑
|
||||
| What are the most common cells that line the surface of the alveoli and are therefore associated with the exchange of gases within the lungs? | show 🗑
|
||||
| What type of cells secrete mucus in the respiratory tract? | show 🗑
|
||||
| What is the connective tissue that surrounds each lung called? | show 🗑
|
||||
| show | atmospheric pressure
🗑
|
||||
| show | atmospheric; intra-alveolar
🗑
|
||||
| Name one of the four pulmonary pressures involved in respiration and describe how that pressure affects ventilatoin. | show 🗑
|
||||
| show | gas exchange
🗑
|
||||
| show | alveolar takes into account dead air space
🗑
|
||||
| show | FVC test-maximum inhale followed by a forceful exhale. Low FVC indicates restrictive pulmonary disease.
🗑
|
||||
| show | FEV- % of FVC that can be exhaled within a certain length of time (usually 1 second). Low FEV indicates obstructive pulmonary disease.
🗑
|
||||
| What is Internal Respiration? | show 🗑
|
||||
| What is external respiration? | show 🗑
|
||||
| show | Intrapleural, intra-alveolar
🗑
|
||||
| Is it more advantageous for lungs to have low or high compliance? | show 🗑
|
||||
| show | Decrease elasticity=increase compliance. Decrease surface tension=increase compliance.
🗑
|
||||
| show | breath less; decrease H+ secretion
🗑
|
||||
| show | secrete surfactant; increase compliance
🗑
|
||||
| show | exchange of gases between air and blood by diffusion
🗑
|
||||
| show | breath more; increase H+ secretion
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
