What is a blister?
Name: Craig E Tanner
What is happening, on a molecular level, when a person gets a
blister, for example, from a burn?
A blister results when cells have been damages, often causing
immune cells to release histamine, which causes the general inflammatory
response. This causes fluid to be released from cells, causing the
blistering effect under the skin. Do you want more detail?
