1

Between an adult male, female, elder, and baby which has the higher body water content?

the baby due to low body fat therefore low bone mass

2

Why do males have 10 percent more body water content that females?

Males have more skeletal muscle than women who have higher body fat

3

What are the 2 main fluid compartments?

Intracellular fluid and extracellular fluid

4

What are the 2 subparts of the extracellular fluid? Percentages?

Plasma- 20%
Interstitial fluid-80%

5

What is the fluid in the blood called?

plasma

6

Which of the compartments consist of 2/3 total fluid content?

intracellular fluid

7

What is the fluid between cells called?

Interstitial fluid

8

Which of the compartments consist of 1/3 total fluid content?

Extracellular fluid

9

What is the percentage of the ICF in the body?

40%

10

What is the percentage of ECF in the body?

20%

11

What is the percentage of the total body weight of ECF and ICF?

60%

12

Nonelectrolytes

do not dissociate in water; no charged particles are created

13

Electrolytes

dissociate into ions in water; ions conduct electrical current

14

What are some examples of electrolytes?

acids, bases, salts, and some proteins

15

What are some examples of nonelectrolytes?

glucose and most organic molecules

16

What is the major cation in the ECF?

Na+

17

What is the major anion in the ECF?

Cl-

18

What is the major cation in the ICF?

K+

19

What is the major anion in the ICF?

HSO4-(2-)

20

Where are the electrolyte concentrations similar except for higher protein content of plasma?

ECF

21

Where are there more proteins than in plasma?

ICF

22

Where do exchanges between plasma and IF occur?

Across capillary walls

23

Where do exchanges between IF and ICF occur?

Across plasma membranes

24

What must occur for the body to remain stable?

its inout through ingestion or metabolic production = its output through excretion or metabolic consumption

25

Which 2 factors are regulated to maintain fluid balance?

1. ECF osmolality
2. ECF volume

26

How is ECF osmolality regulated?

must be regulated to prevent swelling or shrinking of cells

27

What is ECF osmolality involved in maintaining?

water balance

28

How is ECF volume regulated?

must be regulated to help maintain BP

29

What is ECF volume involved in maintaining?

maintaining sodium balance

30

What leads to net water flow?

a change in solute concentration in any compartment
