Anatomy Chapter 25 (Urinary System) Test Bank | Complete
UPDATED ACTUAL Exam Questions and CORRECT Answers
Graded A+
Question 1.
Urine should be...
Correct Answer: Color - pale yellow to deep amber
odor - odorless
pH - 4.5-8.0 (usually more acidic)
Osmolarity - 40-1350 mOsmol/kg
WBC - 0-2 HPF (high power field)
Protein, nitrites, blood, glucose -none
Bilirubin - (-0.3 mg/100 mL)
Question 2.
Why should a sick person get a urinalysis?
Correct Answer: It can help diagnose and monitor a wide range of health
conditions, including urinary tract infections (UTI), disease(s), and diabetes
Question 3.
Identify parts of the urinary system
Correct Answer: renal artery, renal vein, kidney, ureter, bladder, and urethra
Question 4.
What kind of epithelial tissue cells is the bladder and ureters made of?
Correct Answer: Transitional epithelial tissue cells
‣ Describe how a person knows that they need to go to the bathroom -
✓✓When the bladder fills, stretching its walls and activating nerves that send
signals up the spinal cord to your brain, creating a sensation of fullness and
pressure that tells you its time to urinate
Question 5.
Why is there a renal artery and vein coming in and out of kidneys?
Correct Answer: Kidneys need massive blood flow to act as the body's primary
filters, removing waste, regulating fluids, and balancing electrolytes. Arteries
bring 'dirty' blood in and veins taking 'clean'/deoxygenated blood out
Question 6.
Describe some of the problems that a person may have if they damaged the renal
pyramids of the kidney
, Correct Answer: Symptoms like blood in urine, painful urination, fever,
fatigue, and swelling in hands and feet
Question 7.
How does fluid move for tubular filtration?
Correct Answer: Urine forms by glomerular filtration (from blood to tube),
tubular reabsorption and tubular secretion, all of which occur in the nephrons
Question 8.
What is tubular absorption?
Correct Answer: Fluid moves from tube to blood
Question 9.
What is tubular secretion?
Correct Answer: Fluid moves back from the blood into the tube again
Question 10.
Parts of the kidney
Correct Answer: cortex, renal pyramids, medulla, minor calyx, major calyx,
renal pelvis, renal artery, renal vein, renal hilum
‣ Parts of a nephron -✓✓Artery, bowman's capsule, glomerulus, proximal
convoluted tubule, distal convoluted tubule, loop of Henle, collecting duct
Question 11.
Explain what is filtered and how it is filtered at the glomerulus, and what is lost
Correct Answer: Glomerular filtration removes water and these dissolve
substances from the plasma of blood: sodium, potassium, calcium, magnesium
positive ions, negative ions of chloride, bicarbonate, amino acids, glucose,
urea, creatinine.
99% of the fluid gets reabsorbed in the renal tubules
Question 12.
Explain where most of the items forced out at the glomerulus are reabsorbed into the
blood
Correct Answer: The proximal convoluted tubule
