CSCC BIO 2301 Unit 4 questions
with 100% correct
answers(GUARANTEED SUCCESS)
- answer
List 5 substances eliminated in the urine by the kidneys - answer
Ions/Electrolytes
Water Balance
pH/Hydrogen Ions
Organic Nutrients
Nitrogenous Waste Management
List 4 nitrogen containing waste products found in the urine - answer
Creatinine
Uric Acid
Urea
Ammonium ions
What is the functional unit of the kidney? - answer Nephron
What are the 2 parts of the nephron? - answer Glomerulus
Renal Tubule
What are the 4 parts of the renal tubule? - answer Bowman's capsule
Proximal Convoluted Tubule
Loop of Henle
Distal Convoluted Tubule
, List the 3 processes involved in making urine and state the main region of
the nephron where each occurs. - answer Filtration - glomerulus to
Bowman's Capsule
Reabsorption-Proximal Convoluted Tubule
Secretion -distal convoluted tubal
What gets filtered? - answer Everything in the plasma (but NOT plasma
proteins) will be filtered
What 2 things does filtration require? - answer requires a filter (with
holes, aka: fenestrations) and also a pressure gradient.
What 2 unique characteristics of the glomerulus make it perfectly suited
for filtration? - answer Arterioles are high pressure vessels and so there is
high pressure coming in to the glomerulus (through the afferent arteriole)
and high pressure leaving the glomerulus (through the efferent arteriole)
What are the 3 pressures involved in filtration? - answer Glomerular
Hydrostatic Pressure (GHP)
Glomerular Osmotic Pressure (GOP)
Capsular Hydrostatic Pressure (CHP)
What is the definition of glomerular filtration rate (GFR) - answer the
volume of filtrate formed every minute. It is directly related to the net
filtration pressure
What is the normal value for GFR? - answer 125 mL/min
The clearance of what substance can be used to measure GFR? - answer
creatinine
Why is GFR regulated? - answer it is VERY important that GFR stays at its
normal value of 125 ml/min because the rate of reabsorption depends on
the rate of filtration.
