👉 The huge fluid, often referred to as the interstitial fluid or extracellular fluid, is a vital component of the body's internal environment, primarily found outside of cells. It fills the spaces between cells and within the cavities of tissues, making up about 60% of the total body water. This fluid plays a crucial role in maintaining cellular function by facilitating the transport of nutrients, oxygen, and waste products. It also acts as a medium for chemical reactions and helps in the regulation of temperature, pH levels, and pressure within tissues. Composed mainly of water, it contains electrolytes, proteins, glucose, and various waste products, all essential for sustaining life processes and ensuring the proper functioning of organs and systems.
