👉 IL-Fluid, or Interstitial-Lymphatic Fluid (ILF), is a unique fluid found within the interstitial spaces of tissues, playing a crucial role in maintaining tissue homeostasis and immune function. Unlike blood plasma, which circulates through the vascular system, ILF is produced by the movement of interstitial cells and flows through the lymphatic vessels. This fluid helps in the transport of nutrients, waste products, and immune cells between tissues and lymph nodes, facilitating immune surveillance and response. ILF also aids in the removal of metabolic waste and contributes to the regulation of interstitial pressure, ensuring proper tissue function and health. Its dynamic nature allows it to adapt to changes in tissue activity and stress, making it essential for overall physiological balance.
