👉 The remaining fluid, also known as interstitial fluid or extracellular fluid, constitutes the liquid that fills the spaces between cells and within the body's cavities, such as those surrounding organs and in body cavities like the brain and spinal cord. This fluid plays a crucial role in maintaining the body's homeostasis by facilitating the transport of nutrients, waste products, and signaling molecules. It also helps cushion and protect organs, ensuring they function properly without direct contact with each other. The remaining fluid is produced by various tissues and organs, including the kidneys, liver, and bone marrow, and is constantly being replenished and balanced by the body's complex fluid regulation mechanisms.
