Fluid and pH Grade A q&a
Fluid balance in the human body is roughly equivalent to:
pH balance.
water balance.
nonelectrolyte balance.
acid-base balance. - (correct answer)water balance
What system is responsible for the most common route of water loss from the body?
digestive system
respiratory system
urinary system
integumentary system - (correct answer)Urinary system
Water loss from the body that we do not notice is known as
sensible water loss.
obligatory water loss.
nonsense water loss.
insensible water loss. - (correct answer)Insensible water loss
What part of the brain controls the thirst mechanism?
hypothalamus
pons
medulla oblongata
cerebellum - (correct answer)Hypothalamus
What is the most potent stimulus of the thirst mechanism?
atrial natriuretic peptide (ANP)
, osmolarity of the plasma
increased blood pressure
increased plasma volume - (correct answer)Osmolarity of the plasma
What type of neuron detects changes in the number of solute particles in plasma?
nociceptor
baroreceptor
osmoreceptor
chemoreceptor - (correct answer)Osmoreceptor
Which hormone does NOT regulate fluid balance in the body?
antidiuretic hormone (ADH)
atrial natriuretic peptide (ANP)
angiotensin-II
vitamin D3 (calcitriol) - (correct answer)vitamin D3 (calcitriol)
What effect does an increase in antidiuretic hormone (ADH) have on the volume of
extracellular fluid (ECF)?
ECF decreases when antidiuretic hormone (ADH) is present.
ECF increases initially, then decreases when antidiuretic hormone (ADH) is present.
ECF increases when antidiuretic hormone (ADH) is present.
Antidiuretic hormone (ADH) has no effect on ECF. - (correct answer)ECF increases
when antidiuretic hormone (ADH) is present.
What condition accompanies over hydration, or hypotonic hydration?
hyponatremia
hyperglycemia
hypercalcemia
