) What are the differences between intercellular fluid, extracellular fluid, and interstitial fluid?
a. ICF- found inside the cell
b. ECF- in between the vessels
c. ISF- filtrate in the blood, between cells and capillaries
B) What are osmotic pressure and oncotic pressure?
a. Osmotic pressure is the pressure exerted by the solutes in solution; in the bloodstream,
osmotic pressure is exerted by electrolytes (mainly Na) and plasma proteins; Osmotic
pressure is a force that pulls water into the bloodstream from the ICF and ISF
b. Oncotic pressure also called colloidal osmotic pressure is a type of osmotic pressure
exerted specifically by albumin in the bloodstream. Like osmotic, but uses albumin
C) What are the major solutes in the body?
a. Potassium
b. Magnesium
c. Phosphates
d. Sodium
D) What are the differences between isotonic, hypotonic, and hypertonic solutions?
a. Isotonic—has same tonicity as blood 0.9% NS
b. Hypotonic—fewer particles and more water than blood 0.45% NS; given when
dehydrated causes a fluid shift from ECF to ICF to deliver water to the body
c. Hypertonic—3.0% NaCl contains more particles and less water than blood; solutes
added to bloodstream cause fluid to shift from ICF to ECF causing body cells to shrink
causes cells to diminish swelling especially in cerebral edema
E) Starlings law of capillary forces balances which two forces?
a. Explains that there are two major forces at every capillary cell interface in the body;
hydrostatic and osmotic pressure. Hydrostatic pressure forcesfluid out of the capillary
pores into the tissues and osmotic pressure pulls water from the tissues into the
bloodstream (to obtain homeostasis)
