Final answer:
The important peritoneal folds do not include the B) round ligament (ligamentum teres).
Step-by-step explanation:
The important peritoneal folds do not include the round ligament (ligamentum teres).
The peritoneum is a broad serous membranous sac that surrounds and holds in place the abdominal organs.
It is composed of two regions: the parietal peritoneum, which lines the abdominal wall, and the visceral peritoneum, which envelops the abdominal organs. The peritoneal folds are folds of the peritoneum that help support and hold the organs in place.
The major peritoneal folds include the falciform ligament, the greater omentum, the lesser omentum, and the mesentery.
