👉 Tissue fluid, also known as interstitial fluid, is a vital component of the body's extracellular environment, existing between the cells and the extracellular matrix in tissues. It plays a crucial role in maintaining tissue homeostasis by facilitating the exchange of nutrients, waste products, and signaling molecules between cells and the bloodstream. This fluid is derived from plasma and is constantly being produced by cells through processes like filtration and secretion, while also being reabsorbed into the bloodstream via the lymphatic system. Tissue fluid is essential for proper cellular function, as it helps to remove metabolic waste and maintain the necessary osmotic balance, ensuring that cells can function optimally within their microenvironment.
