||||
|---|---|---|---|---|---|
| show | Respiratory and conducting
🗑
|
||||
| Where does the exchange of gas between air and blood occur? (which zone) | show 🗑
|
||||
| What are the 3 functions of "respiration"? | show 🗑
|
||||
| show | breathing; the mechanical process that moves air into and out of the lungs
🗑
|
||||
| Gas exchange occurs between: | show 🗑
|
||||
| show | the tissues liberate energy from the reactions of cell respiration
🗑
|
||||
| Ventilation and exchange of gases (oxygen and carbon dioxide) between the air and blood | show 🗑
|
||||
| Gas exchange between the blood and other tissues and oxygen utilization by the tissues | show 🗑
|
||||
| Concentrations of oxygen in air and blood: | show 🗑
|
||||
| show | CO2 is higher in the blood than the air, so it diffuses OUT of the blood and into the air
🗑
|
||||
| show | It occurs entirely by diffusion through lung tissue.
🗑
|
||||
| show | alveoli
🗑
|
||||
| show | an estimated 300 million
🗑
|
||||
| show | 60-80 sq. meters or 760 sq. ft.
🗑
|
||||
| How thick is an alveolus? (singular for alveoli) | show 🗑
|
||||
| show | It speeds it up
🗑
|
||||
| How thick is the air blood barrier? | show 🗑
|
||||
| 2 types of alveolar cells: | show 🗑
|
||||
| show | comprise 95-97% of the total surface area of the lung. Gas exchange with the blood primarily occurs through these cells. Very thin.
🗑
|
||||
| Type II alveolar cells: | show 🗑
|
||||
| What is included in the respiratory zone? | show 🗑
|
||||
| show | it includes all of the anatomical structures through which air passes before reaching the respiratory zone.
🗑
|
||||
| Flow of air in the respiratory system | show 🗑
|
||||
| Sturdy tube supported by rings of cartilage | show 🗑
|
||||
| show | pharynx
🗑
|
||||
| show | glottis
🗑
|
||||
| The ventricular and vocal chords. Also called the voice box. Guards the entrance to the trachea. | show 🗑
|
||||
| show | adam's apple
🗑
|
||||
| The structures of the conducting zone serve additional functions such as: | show 🗑
|
||||
| show | the mucus traps small particles in the inspired air and thereby performs a filtration function
🗑
|
||||
| Diaphragm | show 🗑
|
||||
| Contains the liver, pancreas, gastrointestinal tract, spleen, genitourinary tract, and other organs | show 🗑
|
||||
| show | thoracic cavity
🗑
|
||||
| Central region | show 🗑
|
||||
| Pleural membranes | show 🗑
|
||||
| parietal pleura | show 🗑
|
||||
| show | deep layer, covers the surface of the lungs
🗑
|
||||
| show | pressure differences induced by changes in lung volumes
🗑
|
||||
| Physical properties of the lungs that influence ventilation | show 🗑
|
||||
| Airflow through bronchioles proportions: | 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.
