Interstitial fluid - Definition

January 2017


Definition

Interstitial fluid is 90% water, and occupies the empty space between the cells and blood capillaries. It functions as a facilitator of interaction between these two organisms. Excess of interstitial fluid is dealt with by the lymphatic capillaries, which turn the superfluous fluid into lymph. This is then transported to the neck where it once again joins the bloodstream via the left subclavian vein. Interstitial fluid has a relatively similar composition to blood plasma.
