What do melena and hematochezia indicate?

Rectal bleeding is when blood passes from the rectum or anus. Bleeding may be noted on the stool or be seen as blood on toilet paper or in the toilet. The blood may be bright red. The term “hematochezia” is used to describe this finding.
Is melena from upper or lower GI?
