👉 An "an-fluid" refers to a type of bodily fluid that is produced by the body's immune system, particularly during an infection or inflammation. This fluid is primarily composed of water, proteins, electrolytes, and various immune cells such as white blood cells. When the body detects a pathogen like a virus or bacteria, it triggers an inflammatory response that leads to the production of these fluids. These an-fluids help to combat the infection by containing and neutralizing the invading pathogens, promoting healing, and facilitating the removal of damaged cells. The most common example of an-fluid is mucus, which forms in the respiratory tract to trap and expel foreign particles.
