Question basic science - Difference between pus and ulcer

In acute inflammation, there are 4 major exudates that are produced, two of which are pus and ulcers. What are the differences between them? Don't they both contain neutrophils and are surrounded by membranes? Thanks very much.

Are you serious?

You really don't know the difference between pus and ulcer?

Wink Re: Pus vs. ulcer

Never mind, I got the answer - ulcers are more severe and could actually involve extensive tissue damage in superficial and deeper layers. In common everyday usage , the two terms are often confused together (e.g ulcerating pus), which was why I got confused.

I think the following link gives a great explanation for the differences between pus and ulcer.

13monument,

No need to judge, I'm pretty sure schiwei was asking about the difference on a microscopic level not macroscopic, which is not as clear.
