What is the function of the cecum?

• A. Absorbs fat
• B. Absorbs water and some vitamins
• C. Digests cellulose
• D. Stores waste until excretion

Answer: (B)

The cecum plays a crucial role in the digestive system, particularly in certain animals like herbivores. Its primary function is to absorb water and some vitamins that are produced during the fermentation process of food. In species that utilize fermentation, the cecum acts as a site where undigested food material is broken down further. This process is vital for maximizing nutrient absorption. While the cecum does not absorb fat, digest cellulose directly, or store waste until excretion, its ability to absorb water significantly contributes to the overall hydration balance and nutrient retrieval in the digestive process. This helps ensure that the animal can efficiently utilize the nutrients extracted from its diet.
