QUESTIONS AND CORRECT ANSWERS

◉ Intracellular fluid (ICF).
Answer: Comprises all fluids within cells


2/3 of TBW


◉ Extracellular fluid (ECF).
Answer: comprises all fluid outside of cell


1/3 of TBW


includes Interstitial fluid & intramuscular fluid


also includes lymph & transcellular fluids (synovial intestinal,
cerebrospinal fluid), sweat, urine, pleural, peritoneal, pericardial,
intraocular fluids


◉ Interstitial fluid.
Answer: Space between cells and outside blood vessels

,◉ Intramuscular Fluid.
Answer: Blood plasma


◉ What are the 3 primary sources of body water?.
Answer: 1- drinking
2- water ingested in food
3- water derived from oxidation metabolism


◉ hydrostatic pressure.
Answer: pushes water


◉ osmotic/oncotic pressure.
Answer: pulls water


◉ Filtration.
Answer: if fluid moves out of the capillary into interstitial space


◉ reabsorption.
Answer: if fluid moves back into the capillary from the interstitial
space

, ◉ Net Filtration/ Starling Forces.
Answer: the forces of filtration and reabsorption working together


forces favoring filtration- forces opposing filtration


◉ Forces Favoring Filtration.
Answer: Capillary hydrostatic pressure (blood pressure)
+interstitial oncotic pressure (water-pulling)


◉ Forces opposing filtration.
Answer: capillary oncotic pressure
+interstitial hydrostatic pressure


◉ 4 forces that determine if filtration or reabsorption occurs.
Answer: 1- capillary hydrostatic pressure
2-capillary oncotic pressure
3-Interstitial hydrostatic pressure
4-Interstitial oncotic pressure


◉ capillary hydrostatic pressure.
Answer: the outward movement of water from the capillary to the
interstitial place (being pushed out)
