Water located in-between cells is referred to as what?

The correct answer is interstitial fluid because it refers specifically to the fluid found in the spaces between cells in tissues. This fluid plays a crucial role in the transportation of nutrients, waste products, and signaling molecules between blood and cells, facilitating cellular function and homeostasis.

Interstitial fluid is a component of the extracellular fluid, which includes all body fluids outside the cells, such as blood plasma and lymph. However, it is distinct from intracellular fluid, which is the fluid contained within the cells themselves. Understanding the different compartments of body fluid is essential in sports nutrition, as hydration status and the balance of fluids can significantly impact athletic performance and recovery.
