Mucous membranes

Mucous membranes are specialized tissues that line various body passages and cavities exposed to the outside environment, such as the mouth, nose, throat, and digestive tract. They produce mucus, a thick, slippery fluid that helps trap dust, germs, and other particles, preventing infections and keeping tissues moist. These membranes play a crucial role in protecting your body, facilitating functions like breathing, digestion, and sensation. They also contain immune cells that help defend against pathogens, ensuring your body's internal systems stay healthy and functioning properly.
