Question 32

Filtration Rate/Starling Equation

Answer 32

Question 33

Interstitium and Starling Equation

Answer 33

Question 34

Blood Pressure

Answer 34

Question 35

Concept of Net Filtration

Answer 35

Question 36

Movement of Water accross Cell Membrane

Answer 36

Question 37

Answer 37

D. Plasma Space, Interstitial same and intracellular space would all loose fluid proportionally. When we sweat we lose more water than we do salt. So ECF becomes concentrated and water will flow from inside to outside cell. But all 3 would loose water proportionally.

Question 38

Answer 38

B. Most of the water would come from the extracellular space (plasma + interstitial) Why is this different? Because when we bleed we lost an isotonic fluid so we didn’t create an osmotic imbalance. Therefore there’s no osmotic force that draws out water from our intracellular space.

Question 39

Isotonic vs. Isosmotic

Answer 39

Question 40

Solutions and Isosmotic vs. Isotonic

Answer 40

Question 41

Answer 41

D. Expansion of both the extracellular space and the intracellular space ## Footnote Glucose get’s taken into the cells very quickly and you end up with a infusion of water with essentially no solute. This is very bad. Blood cells will undergo hemolysis — RBC’s would explode because they would take in the water.
