Wormlike sac that outpockets from the cecum?
The wormlike sac that outpockets from the cecum is called the appendix. It is a small, finger-shaped pouch located at the beginning of the large intestine. The function of the appendix in humans is not entirely clear, but it is believed to play a role in the immune system. Inflammation of the appendix, known as appendicitis, can be a medical emergency and may require surgical removal.
