Definition
|
|
Term
| WHAT 2 THINGS DOES SURFACTANT DO? |
|
Definition
| KEEP ALVEOLI OPEN AND DECREASE SURFACE TENSION. SURFACE TENSION IS WHAT CAUSES A SOAP BUBEL TO COLLAPSE. WITHOUT SURFACTANT, THE SURFACE TENSION IS TOO HIGH AND THE ALVEOLO COLLPASE. NO NEONATES THAT ARE BORN PRIOR TO SURFACTANT PRODUCTION WILL HAVE COLLAPSED ALVEOLI. |

Definition
| THEY ARE MONOCYTES THAT HAVE LEFT THE BLOOD SYSTEM. IS THEY ARE CIRCULATING THEN THEY ARE CALLED MONOCYTES. IF THEY ARE OUTSIDE OF THE CIRCULATORY SYSTEM THEY ARE CALLED MACROPHAGES. |
