Water movement between ICF compartment and ECF compartment is primarily a function of what? Osmotic Forces In addition to osmosis, what force is involved in the movement of water between the plasma and interstitial fluid spaces? Hydrostatic pressure At the arterial end of capillaries, why does fluid move from the intravascular space into the interstitial space? Capillary hydrostatic pressure is higher than the capillary oncotic pressure Low plasma albumin causes edema as a result of a r...

Hydrostatic Pressure Correct Answer--Pushing pressure -Mechanical force of water pushing against cellular membranes Oncotic pressure / gradient Correct Answer-- Pulling effect on water, dependent on albumin(colloid) -Oncotic pressure exerted by proteins in the plasma pull water into the circulatory system Intracellular fluid (ICF) Correct Answer--Fluid within cells and comprises approx. 2/3 (40%) total body water Extracellular fluid (ECF) Correct Answer--Fluid outside the cells and co...

Ans: intracellular = two-thirds. extracellular = one-third. Is the ICF or ECF subdivided into more categories? what are these? Ans: ECF. Into intravascular and interstitial. What percentage of the ECF is intravascular fluid? interstitial? Ans: intravascular 25%. (4-5%) interstitial 75%. (15-16%) beca...

Water movement between ICF compartment and ECF compartment is primarily a function of what? Osmotic Forces In addition to osmosis, what force is involved in the movement of water between the plasma and interstitial fluid spaces? Hydrostatic pressure At the arterial end of capillaries, why does fluid move from the intravascular space into the interstitial space? Capillary hydrostatic pressure is higher than the capillary oncotic pressure Low plasma albumin causes edema as a resu...

Fluid regulation mechanisms - Answer--The thirst center. The thirst center in the hypothalamus stimulates or inhibits the desire for a person to drink. -Antidiuretic hormone. ADH regulates the amount of water the kidney tubules absorb and is released in response to low blood volume or in response to an increase in the concentration of sodium and other solutes in the intravascular fluids. -The RAAS. The RAA system controls fluid volume, in which when the blood volume decreases, blood flow t...

What makes up 1/3 of the body's water content? extracellular fluid (ECF)--15 liters Where is intracellular fluid (ICF)? Figure 13-1 inside cell membranes What are fluids used to deliver? dissolved nutrients, electrolytes, cells for immunity, and histamine Where does aldosterone come from and when is it secreted? adrenal cortex; sodium levels in ECF are too low or have dropped Why is aldosterone secreted? to prevent water and sodium loss aldosterone actions -triggers kidney nephrons to reab...
