Chapter 43, Part 1 Review

We lose fluids through

• sweat

• breath

• feces

• all of the above

The passive movement of substances across a membrane to achieve equal concentration is known as:

• acid-base balance

• neutral charged ions

• fluid excretion

• diffusion

Water movement between the ICF and ECF compartments is determined by:

• Osmotic forces

• Plasma oncotic pressure

• Antidiuretic hormone

• Buffer systems

what % of the body’s water is ECF

• 33

• 40

• 70

• 90

Substances (like salts) which break apart or dissolve in a water solution to form electrically charged particles

• secretions

• diuretics

• solutes

• electrolytes

The dissociated particles of an electrolyte

(Hint: they carry either a + or - charge)

• solutes

• ions

• hormones

• solutes

Which of the following "fluid compartments" makes up the majority of the body's fluid percentage?

• plasma

• lymph

• intracellular

• interstitial

The intracellular fluid compartment makes up what percentage of the body's distribution of water?

• approx 10%

• approx 35%

• approx 65%

• approx 90%

This hormone is released from the posterior pituitary and promotes water reabsorption from the kidney tubule back into the blood

(Hint: it assists in reducing fluid output)

• norepinephrine

• antidiuretic hormone

• aldosterone

• atrial natriuretic hormone

This hormone is released by the adrenal cortex and increases Na+ reabsorption by the kidney tubules

(Hint: it reduces water output from body)

• norepinephrine

• antidiuretic hormone

• aldosterone

• atrial natriuretic hormone
