1. Lubrication: Mucus is produced and secreted by the lining of the alimentary canal to provide a layer of lubrication. This helps in the smooth movement of food through the digestive tract, preventing any friction or damage to the delicate tissues.
2. Protection: Mucus acts as a protective barrier against harmful substances and pathogens that may be present in the food or drink we consume. It traps and immobilizes bacteria, viruses, and other microorganisms, preventing them from entering the body and causing infections. Mucus also protects the inner lining of the gastrointestinal tract from damage caused by stomach acid, digestive enzymes, and other irritants.
