APHY 201 Ch 19-20 Kidneys and Fluids Ivy Tech Questions with Correct
Answers
Question 1:
1. regulation of ECF volume and blood pressure
Answer:
function of the kidneys
Question 2:
6. returns useful chemicals to blood
Answer:
control blood pressure
Question 3:
1. proteins --> amino acids --> forms ammonia
Answer:
urea
Question 4:
Largest solute in component in urine
Answer:
by liver
Question 5:
Nitrogenous waste excreted in urine. Creatinine clearance is a measure of the efficiency of the
Answer:
creatinine
kidneys in removing (clearing) creatinine from the blood and can be used as an rough estimate
of
Question 6:
What body systems carry out excretion?
Answer:
GFR since it is freely filtered, not reabsorbed, but is a bit secreted.
, Question 7:
1. integumentary
Answer:
sweat production (contains water, salt, urea)
Question 8:
2. respiratory
Answer:
expired air contains CO2 and water vapor
Question 9:
3. digestive
Answer:
feces contains water, salts, CO2, lipids, bile pigments, cholesterol, other metabolic waste, and
food residue
Question 10:
4. urinary afferent arteriole pressure efferent arteriole
with high osmotic pressure. renal portal system
arteriole -> peritubular capillaries (2nd capillary bed)
Answer:
many metabolic wastes, toxins, drugs, hormones, salts, H+, and water
blood vessel that supplies the glomerulus and is important in regulation of glomerular blood
form from a convergence of the capillaries of the glomerulus. They play an important role in
maintaining the glomerular filtration rate despite fluctuations in blood pressure. Contains blood
two capillary beds in a row: afferent arteriole -> glomerulus (1st capillary bed) -> efferent
Question 11:
What would cause an increase in glomerular filtration rate (GFR)?
Answer:
afferent arteriolar vasodilationon; efferent arteriolar vasoconstriction
Question 12:
What would cause an decrease in glomerular filtration rate (GFR)? peritubular capillariesdistal
convoluted tubules. Contain blood with high osmotic pressure. vasa recta
Answer:
afferent arteriolar vasoconstricton; efferent arteriolar vasodilationbranch off of the efferent
arterioles supplying the tissue near the glomerulus, the proximal and capillary bed branched
from the efferent arteriole of juxtamedullary nephron. Aids in the
