Definition
The cecum (also spelled caecum) is a pouch-like structure that marks the beginning of the large intestine. It receives undigested material from the ileum of the small intestine. Think of it as the entry point to the large intestine's waste-processing center. It plays a role in absorbing fluids and salts. It also contains a valve that prevents backflow from the large intestine into the small intestine. It's basically a holding tank for waste. 🫙
