(24 cards)
most extracellular fluid found between the cells of the body
interstitial fluid
fluid found as blood plasma like CSF, synovial fluid etc etc
intravascular fluid space
who has more fluid
men 60%
normal fluid intake is through?
- ingestion of liquids and moist foods (2300mL/day)
- metabolic synthesis of water (200mL/day)
normal fluid loss is through?
- the kidneys (1500mL/day)
- evaporation from the skin (600mL/day)
- exhalation from the lungs (300mL/day)
- in the feces (100mL/day)
the kidneys excrete excess water through?
dilute urine
the kidneys excrete electrolytes through?
concentrated urine
what hormones promote urinary reabsorption when dehydrated
angiotensin II
aldosterone
what hormone promotes excretion to decrease blood volume
ANP
fluid balance is regulated y what hormones
angiotensin II
aldosterone
ANP
what hormone directly regulates water loss in the kidneys
ADH
what forms when electrolytes dissolve and dissociate
ions
4 general functions of ions
osmosis
acid-base balance
electrical current
cofactors
used to measure the number of electrolytes
milliequivalent (mEq)
osmotic pressure exerted by proteins on either side of the capillary membrane is called?
oncotic pressure
compares the forces at the arterial end of capillary with those at the venous end
starling equation
occurs when excess interstitial fluid collects, causes swelling in the tissues
edema
this is a major homeostatic challenge that keeps the body fluids at an appropriate level
pH
acts quickly to temporarily bind excess H+ or OH-
buffer system
how is pH corrected
through breathing
hypoventilation
respiratory acidosis
hyperventilation
respiratory alkalosis
non-respiratory acid accumulates
metabolic acidosis
non-respiratory acid lost
metabolic alkalosis
