interstitial fluid

Interstitial fluid is a clear, water-like substance found in the spaces between cells in tissues throughout the body. It acts as a medium for nutrients, waste products, and gases to move between blood vessels and cells. This fluid helps maintain a stable environment for cells, providing essential substances while removing waste. It’s a vital component of the body’s overall fluid balance and plays a crucial role in cellular function and health. Essentially, interstitial fluid facilitates communication and substance exchange within our body's tissues.
