👉 The closer fluid, often referred to as the "closer" or "inner" fluid, is a type of fluid found in the innermost layers of certain biological systems, such as the inner lining of blood vessels or the walls of some organs. This fluid is typically in closer contact with the surrounding tissue and plays a crucial role in maintaining the integrity and function of these structures. It helps to lubricate surfaces, reduce friction, and facilitate the exchange of nutrients, gases, and waste products between the fluid and the tissues it surrounds. The closer fluid is often rich in proteins, electrolytes, and other essential molecules that support cellular activities and overall tissue health.
