| There are two groups of phagocytic cells, white blood cells polymorphonuclear leukocytes and tissue cells. |
| Interestingly, serum enhanced the phagocytic ability of acanthamoebae, as measured by bacterial uptake. |
| Beyond this phagocytic action, they do not appear to play any direct part in the reparative process. |
| In all of these cases, the secondary plastid is enclosed by multiple membranes, the outermost of which is apparently a derivative of the original phagocytic vacuole. |
| The complement system and phagocytic cells are also used by most forms of invertebrate life. |
| Antibodies bind to and neutralize pathogens or prepare them for uptake and destruction by phagocytic cells. |
