| 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. |
| There are two groups of phagocytic cells, white blood cells polymorphonuclear leukocytes and tissue cells. |
| The complement system and phagocytic cells are also used by most forms of invertebrate life. |
| Beyond this phagocytic action, they do not appear to play any direct part in the reparative process. |
| Again, the function of this mesothelium apart from the germ-cell is essentially excretory and phagocytic. |
