👉 Fluid, often found in the human digestive system, acts as a lubricant and facilitates the movement of food through the gastrointestinal tract. It is secreted by the submucosal glands in the lining of the intestines, particularly the ileum and colon, and helps to break down large food particles into smaller, more manageable pieces. This process aids in the smooth passage of nutrients and waste products, ensuring efficient digestion and absorption. Additionally, fluid produced by fluid in the intestines helps maintain the mucosal lining's health and supports the growth of beneficial gut bacteria.
