👉 Collecting fluid, also known as interstitial fluid, is a vital component of the body's circulatory system, existing between cells and within the spaces between them. It acts as a medium for the exchange of nutrients, gases, and waste products between blood vessels and cells. This fluid is derived from both plasma and interstitial spaces, with a composition that closely resembles plasma but with lower protein concentrations due to filtration processes. Collecting fluid flows through the body via lymphatic vessels, eventually returning to the bloodstream, where it completes its role in maintaining cellular homeostasis and facilitating the transport of substances necessary for cell function and waste removal.
