Verified step by step guidance

Understand the term 'interstitial fluid': Interstitial fluid is a type of extracellular fluid that exists in the spaces between cells in tissues. It plays a crucial role in transporting nutrients, oxygen, and waste products between cells and the bloodstream.

Differentiate between intracellular and extracellular fluid: Intracellular fluid is the fluid contained within cells, while extracellular fluid is found outside cells. Interstitial fluid is a subset of extracellular fluid.

Clarify the location of interstitial fluid: Interstitial fluid is specifically located in the interstitial spaces, which are the small gaps between cells in tissues. It is not found inside blood vessels or within cells.

Eliminate incorrect options: The option 'It is a type of intracellular matrix' is incorrect because interstitial fluid is extracellular, not intracellular. The option 'It is the fluid contained within cells' is also incorrect for the same reason. The option 'It is the fluid inside blood vessels' refers to plasma, not interstitial fluid.

Confirm the correct answer: The correct description of interstitial fluid is 'It is a type of extracellular fluid found between cells,' as it accurately describes its location and function in relation to organ systems.
