|
|
Term
| partial pressure of oxygen |
|
Definition
|
|
Term
| partial pressure of carbon dioxide |
|
Definition
|
|
Term
| oxygen in blood is indirectly proportional |
|
Definition
|
|
Term
|
Definition
| not enough oxygen to the tissues |
|
|
Term
|
Definition
| partial pressure of oxygen in blood gets lower |
|
|
Term
|
Definition
cannot create enough hemoglobin
decreased amount of oxygen |
|
|
Term
|
Definition
|
|
Term
|
Definition
| cells cannot use oxygen because they have been poisoned |
|
|
Term
| low alveolar pressure of oxygen cause |
|
Definition
low oxygen in the atmosphere
not enough exchange in the lungs |
|
|
Term
|
Definition
destruction of alveoli
reduces surface area for gas exchange |
|
|
Term
|
Definition
thickened alveolar membrane
slows gas exchange
loss of lung compliance may decrease alveolar ventilation |
|
|
Term
|
Definition
fluid in interstitial space
increases diffusion distance
aterial pressure of carbon dioxide may be normal due to higher carbon dioxide soluability in water |
|
|
Term
|
Definition
increased airway resistance
decreases air ventilation
due to constriction of bronchioles |
|
|
Term
|
Definition
| alveolar endothelial cells and capillary endothelial cells to enter the plasma |
|
|
Term
|

|
Definition
| less ability to hold oxygen |
|
|
Term
|
Definition
| less ability to hold oxygen |
|
|
Term
| higher pressure of carbon dioxide |
|
Definition
| less ability to hold oxygen |
|
|
Term
| pressure of carbon dioxide |
|
Definition
| drives respiratory rate stronger because it has the abilty to change the pH |
|
|
Term
|
Definition
| has 2 gamma chains therfore can hold on to oxygen better than maternal hemoglobin |
|

Term
|
Definition
respiratory control system regulates what we breath
needs sensory input |
|
|
Term
|
Definition
info impacts medulla/brain stem
which influences respiratory groups
which influences skeletal muscle |
|
|
Term
