👉 The bulk fluid, often referred to as the interstitial fluid, is a vital component of biological systems, primarily found in animals and plants. It fills the spaces between cells and within tissues, acting as a medium for the transport of nutrients, oxygen, hormones, and waste products. This fluid is crucial for maintaining cellular function, facilitating communication between cells, and ensuring the overall homeostasis of the organism. In animals, it is known as the extracellular fluid, while in plants, it is called the intercellular fluid. The bulk fluid's movement and composition are tightly regulated to support the physiological processes of the organism.
