|
Definition
| The total pressure exerted by a mixture of gases is the sum of individual pressures exerted by each of the component gases in the mixture |

|
Term
| What is active ventilation? |
|
Definition
| Where an animal creates ventilatory currents that flow to & from the REM |
|
|
Term
| What is unidirectional active ventilation? |
|
Definition
| Where the gradient flows across REM in one direction |
|
|
Term

|
Term
| What is tidal ventilation? |
|
Definition

Definition
|
|
Term
| What is concurrent gas exchange? |
|
Definition
| Where medium & blood flow in the same direction |

|
Term
| What is countercurrent gas exchange? |
|
Definition
| Where medium & blood flow in the opposite direction |
|
|
Term
| What is crosscurrent gas exchange? |
|
Definition
| Where blood flow breaks up into streams & each stream exchanges with medium at different point |
