líkamsvessa

Líkamsvessa refers to the liquids produced by the human body as part of normal physiological processes. The term covers a broad range of fluids, both circulating inside the body and secreted or excreted to the outside.

Common internal bodily fluids include blood, lymph, cerebrospinal fluid, and various digestive secretions such as gastric juice, bile, and pancreatic juice. Externally excreted or secreted fluids include urine, sweat, tears, saliva, mucus from the respiratory and digestive tracts, semen, and vaginal secretions. The composition, volume, and appearance of these fluids can vary with age, health, hydration, and disease.

In medicine, analysis of body fluids is central to diagnosis and monitoring. Urinalysis can reveal kidney function and metabolic conditions; blood tests assess systemic health; cerebrospinal fluid analysis aids in diagnosing infections, inflammation, or bleeding in the central nervous system; semen and vaginal secretions can be evaluated for fertility, infections, and gynecological health. Saliva and other fluids are increasingly used in diagnostics and research as noninvasive or supplementary sources of information.

Collection and handling of líkamssvessa require appropriate techniques and biosafety measures. Depending on the fluid, samples may be obtained in clinical settings or at home, stored under suitable conditions, and transported to laboratories for analysis. Some bodily fluids can carry infectious agents, so standard precautions, proper protective equipment, and correct disposal procedures are essential.
