Inflammation: Leukocyte margination
The first cells to arrive at the wound site are the polymorphonuclear leukocytes (PMNs).They have a limited scavenging role, eating and digesting foreign material through acid hydrolytic enzymes.
This slide shows margination of neutrophils on the
endothelial surface of a post-capillary venule, just before
diapedesis into the extravascular space.
