The digestive system of squids is a complex network of organs responsible for processing food and extracting nutrients. It consists of a mouth, esophagus, stomach, cecum, digestive gland, intestine, and anus. The mouth is lined with a radula, a rasping tongue-like organ that helps the squid tear its prey apart. The esophagus connects the mouth to the stomach, which is a muscular organ that secretes digestive enzymes. The cecum is a blind sac that extends off the stomach and is thought to play a role in digestion. The digestive gland, also known as the liver, is responsible for producing digestive enzymes and absorbing nutrients. The intestine is a long, coiled tube that connects the stomach to the anus. It is responsible for absorbing water and electrolytes. The anus is the final opening of the digestive system and is used to expel waste products.
