Biol 373 Unit 4c and 4d Questions With Complete Solutions
__ AVP is made at night Correct Answer More
__ neurons synthesize AVP and thus control vasopressin
secretion Correct Answer hypothalamic
__ produced during aerobic respiration is the main source of
acid in the body Correct Answer CO2
Acidosis affects the nervous system because Correct Answer
neurons are less excitable and the CNS is depressed
Aldosterone acts Correct Answer via intracellular receptors,
yielding gene transcription and synthesizing or modulating
pumps and channels
Aldosterone is Correct Answer a steroid
Alkalosis affects the nervous system as it results in Correct
Answer hyperexcitability of neurons, sensory changes, twitches
and tetanus
Aquaporins are Correct Answer water channels
Are there transports for HCO3- on the apical membrane?
Correct Answer No there are not. The indirect method is used
instead.
Are vessels close enough for heat exchange in the kidney?
Correct Answer No
, AVP __ water therefore preventing __ Correct Answer
conserves, diuresis
Blocking ANG II could be a treatment for Correct Answer
hypertension
Buffers for pH include Correct Answer HCO3- in ECF,
proteins, hemoglobin, phosphate in cells, phosphate, ammonia in
urine
Can kidneys restore lost water? Correct Answer No. Kidneys
can conserve water but not restore.
Countercurrent exchange system Correct Answer System in
which arterial and venous vessels travelling very close with fluid
moving in opposite directions allows for transfer from one
vessel to another
Decreased flow rate leads to __ renin release Correct Answer
increased
Dehydration affects which 2 areas Correct Answer
hypothalamus and adrenal cortex
Dehydration is a result of a __ in osmolarity and a __ of volume
Correct Answer Increase, decrease
