Movement of Fluids

Question 1

Hypertonic

Answer 1

Have a higher osmolality than the body fluids

3% NaCl

Question 2

Hypotonic

Answer 2

Lower osmolality

0.45% NaCl

Question 3

Osmolality

Answer 3

The concentration of dilutes in body fluids determined by the total solute concentration w/in a fluid compartment

Question 4

Osmosis

Answer 4

Primary mode of movement

Water moving from less to high concentrated area

Question 5

Diffusion

Answer 5

Intermingling of molecules (solid, liquid, gas)
High—> low concentration
Equalizer

Question 6

Filtration

Answer 6

Movement of water & particles
High —> Low pressure
Movement between vascular compartment and interstitial fluid

Question 7

Filtration terms

Answer 7

Hydrostatic pressure: the pressure a fluid exerts w/in a closed system on the walls of its container

Question 8

Osmotic pressure

Answer 8

The power of a solution to draw water across a semi permeable membrane

Question 9

Active transport

Answer 9

Used to maintain Na+ ⬆️ in ECF, K+ ⬆️ in ICF. Moves Na+ from cells, and K+ into cells
Lower —> higher concentration
Must have ATP to occur
Na+ K+ pump

Question 10

Isotonic

Answer 10

Has the same osmolality as body fluids 0.9% NaCl (saline)
