The maximum volume of air that can be inspired from the end of a normal respiration | show 🗑
|
||||
Which of the following is not part of the respiratory zone in the respiratory tract? Goblet cells, alveolar macrophages, Type I cells, Alveolar pores | show 🗑
|
||||
show | capillary exchange
🗑
|
||||
Which of the following makes up a layer of epithelial cells that overlies the wall of the alveoli? | show 🗑
|
||||
show | False
🗑
|
||||
There are phagocytic cells within the lungs that move among the alveoli to remove foreign particles. True/False | show 🗑
|
||||
show | respiratory bronchioles
🗑
|
||||
The alveolar dead space is a volume of air that cannot cross the alveoli to remove foreign particles. True/ False | show 🗑
|
||||
The primary force responsible for air moving into the lungs during inhalation is ________________. | show 🗑
|
||||
The amount of air that enters the lungs during normal, restful breathing is called the ____________. | show 🗑
|
||||
show | alveoli
🗑
|
||||
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
🗑
|
||||
What is the function of ciliated cells in the conducting zone? | show 🗑
|
||||
The transition from the conducting to the respiratory zone in the lungs occurs at the ______________. | show 🗑
|
||||
show | Type I alveolar cells
🗑
|
||||
What type of cells secrete mucus in the respiratory tract? | show 🗑
|
||||
show | pleural sac
🗑
|
||||
When air is no longer moving through the respiratory tract and the airway is open to the environment, the pressure within the lung is equal to _____________. | show 🗑
|
||||
The difference between what two pressures drives air into and out of the lungs? | show 🗑
|
||||
show | atmospheric, intra-alveolar, intrapleural, and transpulmonary. Breathing has to do with the differences between atmospheric and intra-alveolar pressures Intrapleural keeps the lungs inflated/ transpulmonary is the distending force across the lung wall.
🗑
|
||||
show | gas exchange
🗑
|

Explain Forced Vital Capacity (FVC) Test and what kind of disease it test for. | show 🗑
|
||||
Explain Forced Expiratory Volume (FEV) test and what it test for. | show 🗑
|
||||
show | Internal respiration- oxygen use within the mitochondria to generate ATP.
🗑
|
||||
show | External respiration- exchange of oxygen and CO2 between the atmosphere and body tissues.
🗑
|
||||
show | Intrapleural, intra-alveolar
🗑
|
||||

🗑
|
||||
What is one way lungs increase or decrease compliance? | show 🗑
|
||||
What is one way the body compensates for metabolic alkalosis? | show 🗑
|
||||
show | secrete surfactant; increase compliance
🗑
|
||||
show | exchange of gases between air and blood by diffusion
🗑
|
||||
What is one way the body compensates for metabolic acidosis? | show 🗑

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.
