Question
Multiple Choice QuestionThe rectum is a ______ structure that connects to the ______ colon.Multiple choice question.intraperitoneal; descendingretroperitoneal; descendingretroperitoneal; sigmoidintraperitoneal; sigmoid
Solution
The correct answer is "retroperitoneal; sigmoid".
Here's why:
-
The rectum is a part of the gastrointestinal tract that follows the sigmoid colon and precedes the anal canal.
-
The term "retroperitoneal" refers to the anatomical space in the abdominal cavity behind (retro) the peritoneum, a membrane that lines the cavity. The rectum is considered a retroperitoneal structure because it is located behind this membrane.
-
The sigmoid colon is the part of the large intestine that is closest to the rectum and anus. It forms a loop that averages about 40 cm in length, and normally lies within the pelvis, but on account of its freedom of movement, it is liable to be displaced into the abdominal cavity.
Therefore, the rectum is a retroperitoneal structure that connects to the sigmoid colon.
