Blood in stool

Also known as Hematochezia, Bloody feces, and Bloody stool

In medicine, when referring to human feces, blood in stool looks different depending on (1) how early it enters the intestines (and thus how much digestive action it has been exposed to) and on (2) how much there is (a little bit, more than a little, or a lot). This is why bright red blood in the stool has different clinical significance (and a different name) than brown or black blood in the stool.
