Here a number of bodily fluid's and their definitions:
and some definitions for existing terms (such as blood).
amniotic fluid: Amniotic fluid is a bodily fluid consisting of watery liquid surrounding and cushioning a growing fetus within the amnion. It allows the fetus to move freely without the walls of the uterus being too tight against its body. Buoyancy is also provided.
aqueous humour:
Aqueous humour is a bodily fluid consisting of a thick watery substance that fills the space between the lens and the cornea.
bile: Bile is a bodily fluid consisting of a bitter, yellow or green alkaline fluid secreted by hepatocytes from the liver of most vertebrates. In many species, bile is stored in the gallbladder between meals and upon eating is discharged into the duodenum where the bile aids the process of digestion of lipids.
blood: Blood is a bodily fluid composed of blood plasma and blood cells suspended within the plasma that circulates around the organism's body. Blood performs may important functions including the supplying of oxygen and nutrients, removal of waste, circulation of white blood cells, detection of antibodes, coagulation, transportation of antibodies and the regulation of pH and body temperature.
blood plasma: Blood plasma is a bodily fluid that comprises the liquid component of blood, in which the blood cells are suspended. It makes up about 55% of total blood volume.
breast milk: Breast milk is a bodily fluid produced that is secreted from two milk-secreting glandular organs on a female's chest.
cerebrospinal fluid: Cerebrospinal fluid is a clear bodily fluid that occupies the subarachnoid space and the ventricular system around and inside the brain. CSF is a clear bodily fluid that occupies the subarachnoid space and the ventricular system around and inside the brain.
chyle: Chyle is a bodily fluid consisting of a milky fluid consisting of lymph and emulsified fats; formed in the small intestine during digestion of ingested fats.
chyme: Chyme is a bodily fluid consisting of a liquid substance found in the stomach before passing through the pyloric valve and entering the duodenum. It results from the mechanical and chemical breakdown of a bolus and consists of partially digested food, water, hydrochloric acid, and various digestive enzymes.
ear wax: Ear was is a bodily fluid consisting of a yellowish, waxy substance secreted in the ear canal of humans and many other mammals. It plays an important role in the human ear canal, assisting in cleaning and lubrication, and also provides some protection from bacteria, fungi, and insects.
excreta: Excreta are bodily fluid consisting of waste matter, such as sweat or feces, discharged from the body.
feces: Feces is an excreta consisting of waste products expelled from an animal's digestive tract through the anus (or cloaca) during defecation.
sweat: Sweat is an excreta consisting primarily of water as well as a smaller amount of sodium chloride that is excreted by the sweat glands in the skin of mammals.
urine: Urine is a liquid excreta containing water and waste products made by the kidneys, stored in the bladder, and leaves the body through the urethra.
interstitial fluid: Interstitial fluid is a bodily fluid consisting of a solution which bathes and surrounds the cells of multicellular animals. It is the main component of the extracellular fluid, which also includes plasma and transcellular fluid.
lymph: Lymph is a bodily fluid consisting of a usually clear coagulable fluid that passes from intercellular spaces of body tissue into the lymphatic vessels, is discharged into the blood by way of the thoracic duct and right lymphatic duct, and resembles blood plasma in containing white blood cells and especially lymphocytes but normally few red blood cells and no platelets.
mucus: Mucus is a bodily fluid consisting of a slippery secretion of the lining of the mucous membranes in the body. It is a viscous colloid containing antiseptic enzymes (such as lysozyme) and immunoglobulins. Mucus is produced by goblet cells in the mucous membranes that cover the surfaces of the membranes. It is made up of mucins and inorganic salts suspended in water.
oronasal secretion: Oronasal secretion is a fluid secreted from the body via the mouth or nose.
pleural effusion: Pleural effusion is a bodily fluid that is produced in exess and accumulates in the pleural cavity, the fluid-filled space that surrounds the lungs. Excessive amounts of such fluid can impair breathing by limiting the expansion of the lungs during inhalation.
pus: Pus is a bodily fluid consisting of a whitish-yellow or yellow substance produced during inflammatory responses of the body that can be found in regions of pyogenic bacterial infections. Pus is produced from the dead and living cells which travel into the intercellular spaces around the affected cells.
saliva: Saliva is a slightly alkaline secretion of water, mucin, protein, salts, and often a starch-splitting enzyme (as ptyalin) that is secreted into the mouth by salivary glands, lubricates ingested food, and often begins the breakdown of starches.
sebum: Sebum is an oily bodily fluid secreted from the sebaceous glads that is made of fat (lipids) and the debris of dead fat-producing cells. In the glands, sebum is produced within specialized cells and is released as these cells burst. Sebum acts to protect and waterproof hair and skin, and keep them from becoming dry, brittle and cracked. It can also inhibit the growth of microorganisms on skin.
synovial fluid: Synovial fluid is a bodily fluid secreted by the synovial membrane into the joint cavity to form a thin layer at the surface of cartilage.
tears: Tears is a bodily fluid consisting of a drop of the clear salty liquid secreted by glands (lacrimal glands) in the eyes. Tears wet the membrane covering the eye and help rid the eye of irritating substances.
vitreous humor: Vitreous humor is a bodily fluid consisting of a clear gel that fills the space between the lens and the retina of the eyeball of humans and other vertebrates.
vomit: Vomit is a bodily fluid consisting of the expulsed contents of the stomach of an organism disgorged through the mouth or nose.
