Mucous cells are specialized cells found in various tissues, including the lining of the gastrointestinal tract and respiratory system. Their primary function is to produce and secrete mucus, a thick, slippery substance that helps protect and lubricate surfaces. Mucus plays a crucial role in trapping pathogens and particles, aiding in their removal from the body. These cells are typically located in goblet cells and mucous glands, where they contribute to the overall health of the tissues they inhabit. By maintaining moisture and providing a barrier against irritants, mucous cells are essential for proper organ function and overall well-being.
