  3. Name vessel D? Answer: Right Renal Artery What is area AB? Answer: adrenal gland Questions:

  4. What is area 9? Answer: renal capsule In which structure is urine stored until it can be expelled from the body, give letter & name it! Answer: BD (urinary bladder) Questions:

  5. Name & indicate function of the structure labeled with *? Answer: Ureters carry urine from the kidney to the bladder Questions: *

  9. An individual is suffering from chronic kidney failure, what would be the result of their Benedict’s & Biuret tests? Answer: - Benedict’s = no sugar + Biuret = excess proteins What is the normal pH of urine? Answer: 4.5-8.0 Questions:

  10. Identify the structure labeled 3 Answer: peritubular capillaries If urine smells like over-ripe apples, what condition may be suspected? Answer: Acetouria/Diabetes Questions:

  13. These are the final branches of the interlobular arteries Answer: Afferent arterioles The arteries between the arterioles & arcuate arteries are called …? Answer: Interlobular Questions:

  14. Identify the structure labeled 5 Answer: arcuate vein These cells along with JG cells form the juxtaglomerular apparatus. Answer: Macula Densa Questions:

  15. Identify the #21 blood vessel Answer: interlobular This term is used to describe the position of the kidneys Answer: retroperitoneal Questions:

  16. Identify the structure labeled w/ the red arrow Answer: urethra What is pyuria? Answer: pus (WBC) in urine Questions:

  20. Which tube represents a + Benedict’s test? Tube on the right (Orange) Name the 3 main stages of urine formation in the order they occur. Answer: Filtration, Reabsorption & Secretion Questions:

  21. What is polydipsia? Answer: Great dehydration which results in feelings of thirst Suppose a urine sample revealed abnormal results, such as protein in the urine. If there is a result differing from the norm (i.e., color, pH, substances present), should the physician always make an immediate diagnosis of a disorder? Why or why not? Answer: Physician may test the urine several times over a certain time period before drawing any conclusions.

  23. What are casts & how do they formed? Answer: molds that are precipitates of proteins & agglutinations of cells (several types: hyaline, epithelial, granular (coarse and fine), fatty, waxy, red-blood cell, and white-blood cell. ) Questions:

  24. Urinalysis is performed, what does a + Benedict’s mean? Answer: Excess sugar in the urine. Elevated concentrations of uric acid in the plasma cause this condition. Answer: Gout Questions:
