| 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. |
| Products of complement activation cause smooth muscle contraction and increased vascular permeability and induce degranulation of phagocytic cells, mast cells, and basophils. |
| The next most common milk leukocyte is the macrophage, which is phagocytic like neutrophils and performs a number of other protective functions. |
| Interestingly, serum enhanced the phagocytic ability of acanthamoebae, as measured by bacterial uptake. |
| The complement system and phagocytic cells are also used by most forms of invertebrate life. |
| In general, chemotactic and phagocytic responses are significantly reduced. |
