In this section you will learn to recognize specific types of inflammatory cells and infiltrates in a histological setting. I am sure you will gain an appreciation for how different the histology will be in the diseased state. Cells and tissue morphology that you may feel quite familiar with, will have a substantially different appearance. After this exercise, you should be familiar with appearance and components of an acute and chronic inflammatory infiltrate, as well as the major actors in the repair process. You should also know the difference between an exudate and transudate. Although the slides for study are listed in numerical order, I recommend studying them in the following order: 27, 90, 48 and 19 first, then go to 9 and 139, then the chronic inflammatory conditions 1, 76 and 77, and finish with the repair cases 7, 43 and 59. Good luck!
