Extracellular Fluid Locations in the Body
Let's dive into the fascinating world of extracellular fluids and discover where they're located throughout our body. Understanding these locations is crucial for grasping how our body maintains homeostasis and supports various physiological functions.
Main Locations of Extracellular Fluid
1. Interstitial Fluid
- Located between cells (in the spaces between tissue cells)
- Makes up about 75% of all extracellular fluid
- Bathes cells and facilitates exchange of nutrients and waste products
Interstitial fluid is often called tissue fluid because it surrounds tissue cells and acts as a medium for cell-to-cell communication.
2. Blood Plasma
- Found within blood vessels
- Represents about 25% of extracellular fluid
- Contains dissolved proteins, nutrients, and other substances
3. Lymph
- Present in lymphatic vessels
- Derived from interstitial fluid
- Helps remove waste products and maintain fluid balance
