👉 Peas fluid, also known as mucin or serous fluid, is a clear, watery substance produced by the lining of various organs and glands throughout the body. It plays a crucial role in lubrication and protection, particularly in the respiratory, reproductive, and digestive systems. In the respiratory tract, it helps to moisten and protect the airways, while in the reproductive system, it aids in lubricating the vagina and supporting sperm movement. In the digestive system, it facilitates the smooth passage of food through the intestines and helps maintain a healthy mucosal lining. This fluid is essential for maintaining optimal physiological functions and overall health.
