URINE INTRO Flashcards
study of microscopes, their uses and their techniques of operation.
Microscopy
commonly used microscope
Bright-Field Compound Microscope
used to observe spirochetes in leptospiral or syphilitic infections
Dark-Field Microscope
used in the identification of malarial parasite
Fluorescent Microscope
used in the study of urinary sediments esp. in differentiating sodium urates and calcium phosphates
Polarizing Microscope
used in the study of urinary sediments, counting platelets and vaginal smears
Phase-Contrast Microscope
for wet preparations without need for special staining techniques
Nomarski Differential Interference Contrast Microscope
for research and special laboratory procedures
Electron Microscope
Gross or macroscopic, chemical and microscopic analyses of the different body fluids other than blood

Nephron
glomerulus, renal tubule, collecting tubules
Nephron
specific gravity of glomerular filtrate
1.008-1.012
pH of glomerular filtrate
7.4 pH
Glomerular filtrate: cell-free, protein free, iso-osmotic with plasma, contains all the filterable mol.
Glomelular filtrate
Tubular reabsorption parts
Proxial convulated tube
Distal convulated tube
Steps in urine formation
Glomerular filtration
Tubular Reabsorption
Tubular secretion
vol. of blood that enter the renal arteries/minute (1200ml/min)
Total Renal Blood Flow
portion of TRBF which actually passes thru the glomeruli and peritubular capillaries
Effective Renal Blood Flow
rate at which blood passes thru the glomeruli to the capsule by filtration (120-130ml/min)
Glomerular Filtration Rate
amount of plasma flowing thru the functional renal tissues/minute (660ml/min)
Effective Renal Plasma Flow
Urine composition
97% Water
3% Solutes
Inorganic Substances
Other substances
Formed elements
ratio of the amount of plasma filtered (ERPF) to the total blood plasma flow(GFR)
Filtration Fraction
Solutes in urine
Urea
Organic substances:creatinine & uric acid
