body fluid, bodily fluids, or biofluids are liquids originating from inside the bodies of living people. they include fluids that are excreted or secreted from the body as well as body water that normally is not. the dominating content of body fluids is body water. approximately 60-65% of body water is contained within the cells (in intracellular fluid) with the other 35-40% of body water contained outside the cells (in extracellular fluid). this fluid component outside of the cells includes the fluid between the cells (interstitial fluid), lymph and blood. there are approximately 6 to 10 liters of lymph in the body, compared to 3.5 to 5 liters of blood. ==list of body fluids==  by type: * intracellular fluid * extracellular fluid **intravascular fluid (blood plasma) **interstitial fluid **lymphatic fluid (sometimes included in interstitial fluid) **transcellular fluid in plants: * plant exudates ==health== body fluid is the term most often used in medical and health contexts. modern medical, public health, and personal hygiene practices treat body fluids as potentially unclean. this is because they can be vectors for infectious diseases, such as sexually transmitted diseases or blood-borne diseases. universal precautions and safer sex practices try to avoid exchanges of body fluids. body fluids can be analyzed in medical laboratory in order to find microbes, inflammation, cancers, etc. ===clinical samples=== clinical samples are generally defined as non-infectious human or animal materials including, but not limited to, blood, saliva, excreta, body tissue and tissue fluids, and also fda-approved pharmaceuticals that are blood products.packaging guidelines for clinical samples - retrieved 7 august 2014. in medical contexts, it
