What is pitting edema?

when you press into the skin, like on the lower extremity & see it leave a depression in the soft tissue

2

What are effusions? What are the 2 types?

collection of fluid in a body cavity
**transudate: fluid that leaves b.v. w/o protein & bunches of cells
**exudate: fluid that leaves the b.v. w/ protein & goodies

3

What does a serous effusion look like?

a transudate w/ mainly fluid & not many or any cells

4

What does a serosanguinous effusion look like?

effusion w/ RBCs
hemorrhage likely occurred

5

What does a fibrinous effusion look like?

this includes fibrin strands
**could be seen in fibrinous pericarditis
**looks like stringy pink things.

6

What is a purulent effusion? What else is this called?

consists of many neutrophils
also called empyema when it is in the pleural space

7

What would a chylous peritoneal effusion look like?

acute & chronic cholecystitis
acute & chronic cervitis

13

When you are healing from inflammation...a lot of times you cause growth of more capillaries & fibroblasts. What type of tissue will this help form?

granulation tissue!

14

What types of inflammatory cells does granulation tissue typically have?

mainly mononuclear cells
some neutrophils may be present

15

What are adhesions?

thin bands of collagenous CT connecting tissues, could cause abnormal positioning of organs
**forms b/c of resolution of inflammation

16

reticulonodular
**b/c of localized areas of granulomas
**they are sorta circular & might have a giant cell w/ the bad guy eaten up.

17

Granulomatous inflammation usu includes which cell types?

epitheloid macrophages
giant cells
lymphocytes
plasma cells
fibroblasts
perhaps some neutrophils

18

Describe the structure of giant cells.

nuclei lined up around the periphery of the cell
pink epitheloid macrophages fill most of the granuloma

19

Describe the structure of epitheloid macrophages in the granuloma.

they have lots of pink cytoplasm
their nuclei are long & stringy

20
