Fluid Balance: Fluid Movement

Question 1

Intracellular Fluid (ICF) (2)

Answer 1

1. Fluid within the cells
2. 2/3s of body fluid is within the cells

Question 2

Extracellular Fluid (ECF)

Answer 2

1. Fluid outside of cells
2. Two compartments
   
   1. Interstitial Fluid: Fluid surrounding cells
   2. Vascular Space: Fluid within the blood vessels

Question 3

Which is the most stable and is fairly resistant to major fluid shifts ICF or ECF?

Answer 3

ICF

Question 4

Which fluid is the least stable; it is quickly lost or gained in response to fluid intake or losses

Answer 4

Vascular fluid is the least stable, fluid in blood vessels

Question 5

1. Which fluid is the reserve fluid?
2. **Replacing fluid **either in the __?__ or __?__ depending on the need

Answer 5

1. Reserve Fluid is the interstitial fluid (fluid surrounding cells)
2. Blood vessles (Vascular fluid) or cells (Intracellular)

Question 6

Osmolarity

Answer 6

Osmolarity: Concentration of solute (particles) per Kg or water, which creates pulling power of that solution for water

Question 7

Isotonic

Answer 7

Isotonic has the same osmolality as normal plasma
