Definition & Meaning of "cecum"

What is "cecum"?

The cecum is a pouch-like structure that marks the beginning of the large intestine in the human body. It is situated in the lower right abdomen, where it receives digested food from the small intestine. The cecum plays a role in absorbing water and electrolytes from the undigested material before it progresses through the rest of the digestive system. Additionally, it serves as a reservoir for the intestinal microbiota, housing beneficial bacteria that aid in digestion and contribute to overall gut health.
