Final answer:
Hematochezia does not refer to the passage of dark and tarry stool.
Step-by-step explanation:
The statement that Hematochezia means the passage of a dark and tarry stool is False. Hematochezia actually refers to the passage of fresh, bright red blood through the rectum. It is often a sign of lower gastrointestinal bleeding, which can be caused by various conditions such as hemorrhoids, diverticulosis, or colorectal cancer.
