| Red Blood Cell's Function? |
|
Definition
-Transports CO2(carbon dioxide) from cells to lungs
-Transports 02(oxygen) from lungs to cells |
|
|

|
Definition
| oxygen carried in the red blood cells |

| White Blood Cell's function? |
|
Definition
-Defend the body from microorganisms that invade tissue or bloodstream (Ex:Mononucleosis)
-Phagocytosis
-provide immunity(antibodies)
|
|
|
Term

Term
| platelets (thrombocytes) function? |
|
Definition
| essential for blood clotting |
|
|
Term
|
Definition
-stimulates liver cells to produce prothrombin which causes faster clotting
-also known as Aqua-Mephyton
