ou are testing a long-dwelling catheter for its biological response using a rat model. After implantation for 4 months you explant the catheter material and surrounding tissue. Histology shows the catheter material surrounded by a thin layer of aligned collagen that is, in turn, surrounded by numerous polymorphonuclear cells. What has occurred? Describe the short term and long term events that led to this outcome. Note: the fact that this is a rat model rather than a human is not the issue - the model is fine.
