Body Fluid composition

water containing electrolytes, blood cells, and other soluble molecules

Intracellular fluid (ICF)

fluid located within the cells



intra--> inside (like how intravenous is inside the vein)

Extracellular fluid

all fluid outside of the cells

Intravascular fluid

fluid inside the blood and lymphatic vessels



vascular volume dictates BP

Interstitial fluid

fluid between cells



inter-->between



(think international, as it means between countries)

, the proportion of dissolved particles in a given weight of fluid (mOsm/kg)

Osmolarity

concentration of dissolved substances in a given volume of fluid

280-300 mOsm/kg

what cells monitor changes in body fluid osmolaltiy

Hypothalamic cells, which control the secretion of ADH to adjust water excretion by

kidneys
