What does friability in the colon mean?

The pattern of inflammation in UC is. associated with several mucosal changes, initially vascular congestion, erythema, and granularity. As inflammation becomes more severe, friability (bleeding to light. touch), spontaneous bleeding, and erosions and ulcers develop.

What is grade 3 ulcerative colitis?
