Urinary System, Urinalysis Post - Lab
Objective:
List the functions of the urinary system. Identify, on a model or image, the urinary system
organs, and state the general function of each. Compare the coure and length of the urethra in
males and females. Identify these regions of the dissected kidney (longitudinal section): hilum,
cortex, medulla, medullary pyramids, major and minor calyces, pelvis, renal columns, and
fibrous and perirenal fat capsules. Trace the blood supply of the kidney from the renal artery to
the renal vein. Define nephron, and describe its anatomy. Define glomerular filtration, tubular
reabsorption, and tubular secretion, and indicate the nephron areas involved theses processes.
Define micturition, and explain the differences in the control of the internal and external urethral
sphincters. Recognize the histologic structure of the kidney and ureter microscopically or in and
image. List the physical characteristic of urine, and indicate the normal pH and specific gravity
ranges. List substances that are normal urinary constituents. Conduct various urinalysis tests and
use them to determine the substances present in a urine specimen. Define the following urinary
conditions: calculu, casts, albuminuria, glycosuria, hematuria, hemoglobinuria, ketonuria, pyuria.
Discuss the possible causes and implications of the conditions list above.
