body fluids

the total water in the body accounts for more than half of body mass (typically 45 kg in a 70 kg man). About two-thirds of the total body water (30 L) is in intracellular fluid (ICF) and one-third (15 L) in extra cellular fluid (ECF) - all body fluids external to cells; of this, blood plasma accounts for ∼3 L, interstitial fluid in the tissues and lymph for ∼12 L. See also hydration status, water balance.


1. the trunk, or animal frame, with its organs.
2. the largest and most important part of any organ.
3. any mass or collection of material.

body cavity
see cavity.
ellipsoid body
formed in degenerating myelin sheaths. Each contains a fragment of myelin apparently undergoing enzymatic digestion around a fragment of degenerating axon.

gelatinous body
a 3-5 mm glycogen-rich body in the dorsal surface of the lumbosacral enlargement of the spinal cord in birds.
geniculate b's (lateral)
two metathalamus eminences, one on each side just lateral to the medial geniculate bodies, marking the termination of the optic tract.
geniculate b's (medial)
two metathalamus eminences, one on each side, just lateral to the superior colliculi, concerned with hearing.
Heinz body, Heinz-Ehrlich body
a dark staining refractile body of erythrocytes, consisting of denatured hemoglobin. See also Heinz body anemia.

body louse
mamillary body
either of the pair of small spherical masses in the interpeduncular fossa of the midbrain, forming part of the hypothalamus.

Pappenheimer body
dark, basophilic, iron-containing granules seen in erythrocytes (siderocytes). Occur in hemolytic anemia.
para-aortic b's
enclaves of chromaffin cells near the sympathetic ganglia along the abdominal aorta, which secrete catecholamines during prenatal and early postnatal life, aiding the adrenal medulla. Tumors of these structures produce clinical signs similar to those of pheochromocytoma.

body surface area (BSA)
the total surface area of the body. Used to calculate drug dosages, particularly in the use of toxic drugs such as those used in cancer chemotherapy. This minimizes errors introduced by variations in distribution, metabolism and excretion of the drug. Several equations can be used to express the area, based on body weight, but conversion tables are usually used. See Table 21.
trapezoid body
transverse ridge crossing the ventral surface of the medulla oblongata.
vitreous body
the transparent gel filling the posterior segment of the eyeball between the lens and retina. Called also vitreous and vitreous humor.
