Question 1

In a healthy young adult, body fluid is

Answer 1

60%

Question 2

Total body water depends on various of factors including

Answer 2

Age, sex, weight and amount of body fat

Question 3

Total body decreases as we

Answer 3

Age (45%)

Question 4

Healthy young man has about ___________ percent of body fluid

Answer 4

60

Question 5

Healthy young woman has about ___________ percent of body fluid

Answer 5

50

Question 6

If there is protein and fat, which one does water attract more?

Answer 6

Protein

Question 7

body fat is hydrophobic, therefore

Answer 7

less fluid

Question 8

Explain the difference between males & females in relation to body fluid

Answer 8

Males have more protein in their body, more skeletal muscle and low body fat, that’s why they have more body water than women. However women have more body fat and small amount of skeletal muscle, therefore less body water than men

Answer 9

1) Low

2) Low

Question 27

What reflects the distribution of Na and K on two sides of cellular membrane ?

Answer 27

Na/ K pump

Question 28

Solutes are unequally distributed because of

Answer 28
