Question 2

components of phospholipid bilayer

Answer 2

◦ Consists of a phospholipid bilayer with glycolipids, cholesterol, and proteins.

Question 3

what maintains membraine fluidity

Answer 3

Fluidity is maintained in a large part by the amount of short-chain and unsaturated fatty acids incorporated
within phospholipids

Question 4

▪ Intracellular Fluid (ICF) –

Comprises ____

Answer 4

▪ Intracellular Fluid (ICF) –

Comprises 2/3 TBW

Question 5

Extracellular Fluid (ECF) –… Comprises

Answer 5

Extracellular Fluid (ECF) –
o Comprises 1/3 TBW
o Consists of plasma and
interstitial fluid (ISF)

Question 6

Obese individuals have a lower or higher

TBW

Answer 6

Obese individuals have a lower

TBW

Question 7

does TBW have an affect on drug dossage

Answer 7

yes The amount of TBW is relevant
for drug dosages because fat
solubility varies with type of drug
and can affect effective
concentration of drug.

Question 8

whats the equation for total body water

Answer 8

(weight) 70 x 0.6

Question 9

how do you konw the percentage of ICF

Answer 9

Take 2/3 of the TBW. ( which remember was just 70 x 0.6)

Question 10

how do you find the total ECF

Answer 10

Take 1/3 of the TBW ( Which rember was just 70 x 0.6 )

Question 11

which is larger ECF OR ICF

Answer 11

ICF is higher

Question 12

total body water is what percentage of body weight

Answer 12

60

Question 13

how do you calculate the interstial fluid and plasma of the extracellular fluid (ECF)

Answer 13

Interstial Fluid (ISF) = 3/4 of of ECF 
Plasma = 1/4 of ECF

Question 14

total concentration of a solute is known as

Answer 14

osmolarity

Question 15

The osmolarity is approx

Answer 15

300 m osm

Question 16

what helps to maintain the intracellular and extacellular envinronments

Answer 16

Sodium ATPase pump

Question 17

is there a lot of Na intracellularlly

Answer 17

no Intracellular Na+ is maintained at a low concentration (which drives the Na+ -
dependent transposrt into the cells) compared with the high Na+

Question 18

what is the primary intracellular cation

Answer 18

❖ The primary intracellular cation is the postassium ion.

Question 19

osmolarity is equal to

Answer 19

osmostic pressure

Question 20

the pressure that pulls water into spaces is called

Answer 20

osmotic pressure or oncotic pressure

Question 21

the pressure that forces pushing water out of spaces is called

Answer 21

Hydrostac pressure

Question 22

the concentration of specific proteins is called

Answer 22

oncotic pressure

Question 23

the concentation of specific solutes is called

Answer 23

osmolarity

Question 24

function of lymphatic tissues

Answer 24

Lymphatic tissues and organs responsible for

providing immunity to disease

Question 25

◦ Net hydrostatic pressure forces water in or out

Answer 25

◦ Forces water out of solution

Question 26

Net osmotic pressure

◦ Forces water in or out of solution

Answer 26

Net osmotic pressure

◦ Forces water into solution

Question 27

◦ Both Net hydrostatic pressure and Net osmotic pressure control filtration and reabsorption through what

Answer 27

◦ Both control filtration and reabsorption through capillaries

Question 28

what 2 factors contribute to net hydrostatic pressure

Answer 28

Capillary hydrostatic pressure (CHP)

2. Interstitial fluid hydrostatic pressure (IHP)

Question 29

net filtation pressure is the difference between what two pressures

Answer 29

◦ Net hydrostatic pressure

◦ Net osmotic pressure

Question 30

what is the net filtration pressure equation

Answer 30

NFP = (CHP – IHP) – (BCOP – ICOP)

Filtration) – (Absorption

Question 31

what occurs a the arterial end of a capillary

Answer 31

At arterial end of capillary:
◦ Fluid moves out of capillary
◦ Into interstitial fluid

Question 32

what happens at the venous end of a capillary

Answer 32

◦ At venous end of capillary:
◦ Fluid moves into capillary
◦ Out of interstitial fluid

Question 33

how much is filtered each day and how much is reabsorbed

Answer 33

24 liters filtered , 20 L absorbed

Question 34

what is the effect of hemmoaraging on capillary dynamics

Answer 34

Capillary Dynamics
◦ Hemorrhaging
◦ Reduces CHP and NFP
◦ Increases reabsorption of interstitial fluid (recall of fluids)

Question 35

what is the effect of dehydration on capilary dynamics

Answer 35

◦ Dehydration
◦ Increases BCOP
◦ Accelerates reabsorption

Question 36

what happens if there is an increase in CHP or BCOP

Answer 36

◦ Increase in CHP or BCOP
◦ Fluid moves out of blood
◦ Builds up in peripheral tissues (edema)
