Why do men have 10% more total body water (TBW) than women? Answer:
They have more lean muscle mass.
Which are the characteristics that describe why infants are more vulnerable to
changes in total body water (TBW)? Answer: 80% of their body weight is
water.
They have a greater body surface area.
They lose weight rapidly in the first six months.
They have a high metabolic rate.
Which change in water homeostasis is seen as people age? Answer: Decreased
muscle mass, resulting in decreased total body water
Which is the best description of an electrolyte found in body fluid? Answer: An
electrically charged particle
Which statements are true about extracellular fluid (ECF)? Answer: It contains
plasma. It has two compartments. It is fluid that exists between the cells.
Which is the purpose of antidiuretic hormone (ADH) in the body? Answer:
Promotes vasoconstriction and water reabsorption
Which processes control fluid balance in the human body? Answer: ADH,
Renin, Aldosterone, Drinking Water, Cellular respiration
Which physiological factors are responsible for the decreased total body water
(TBW) in older adults? Answer: Decreased muscle mass, Decreased fat stores
Plasma is contained in which compartment? Answer: Intravascular

body water reserve? Answer: An obese 76-year-old female
Why are women at greater risk for dehydration? Answer: They have more fat
cells. They have less lean muscle mass.
Which is the best explanation of osmolarity? Answer: A measure of the
concentration of particles in plasma or urine
Which component of plasma is a solvent? Answer: Water
What is the description of diffusion? Answer: Diffusion is the passive
movement of solute across a permeable membrane.
What is the goal of hydrostatic pressure in the body? Answer: To have the body
reach equilibrium
What is the effect of a hypertonic fluid? Answer: To pull water from the
isosmotic fluid space into the hyperosmotic fluid space
What are ways that fluid leaves the body? Answer: Urine
Sweat
Expiration
How does the body maintain homeostasis? Answer: By balancing fluid intake
and output
Which mechanism regulates fluid intake in the body? Answer: Thirst
What is the best description of solutes? Answer: Solutes are particles in the
plasma and urine that can be measured.
