A&P CHAPTER 22: URINARY SYSTEM Flashcards
3 MAJOR FUNCTIONS OF URINARY SYSTEM
EXRETION (REMOVAL OF WASTE FROM BODY FLUID)
ELIMINATION (DISCHARGE OF WASTES FROM BODY)
HOMEOSTATIC REGULATION (OF VOLUME AND SOLUTE CONCENTRATION OF BLOOD PLASMA)
HOW DO KIDNEYS HELP MAINTAIN HOMEOSTASIS
REGULATION OF PH/ACID-BALANCE AND VOLUME OF EXTRACELLULAR FLUID
WHAT HORMONE DOES KIDNEY SECRETE
ERYTHROPOIETIN WHICH HELPS CONTROL RBC PRODUCTION
WHAT VITAMIN DOES THE KIDNEY ACTIVATE
VITAMIN D
WHAT ENZYME DOES THE KIDNEY SECRETE
RENIN WHICH HELPS MAINTAIN BLOOD VOLUME AND PRESSURE
WHAT PROCESS DOES THE KIDNEY CARRY OUT DURING FASTING PERIODS
GLUCONEOGENESIS
WHAT SUPPLIES THE KIDNEYS WITH BLOOD
RENAL ARTERIES
WHAT DO NEPHRONS DO
FUNCTIONAL UNITS OF THE KIDNEY THAT FILTER BLOOD (GLOMULUS) AND RETURN NEEDED SUBSTANCES BACK TO BODY (TUBULE)
WHAT DO KIDNEY COLLECTING DUCTS DO
RESPONSIBLE FOR MAINTAINING WATER AND SODIUM ION BALANCE OF THE BODY WITH TYPE A AND B CELLS, BALANCING ACID/BASES IN BLOOD
GLOMERULAR FILTRATION
INITIATES URINE FORMATION IN RENAL CORPUSCLE
USES HYDROSTATIC PRESSURE TO FORCE FLUIDS AND SOLUTES THROUGH MEMBRANES
GLOMERULAR MESANGIAL CELLS
SPECIALIZED PERICTYES THAT ENGULF MACROMOLECULES CAUGHT IN FILTRATION MEMBRANE
GLOMERULAR FILTRATION RATE WILL DECREASE IF WHAT
INADEQUATE BLOOD PRESSURE
SYMPATHETIC STIMULATION
DECREASED NECESSARY IONS
TUBULAR REABSORPTION
MOVES SELECT SUBSTANCES BACK INTO BLOOD
MECHANISM FOR SODIUM TUBULAR REABSORPTION
PRIMARY ACTIVE TRANSPORT
MECHANISM FOR NUTRIENTS TUBULAR REABSORPTION
SECONDARY ACTIVE TRANSPORT
MECHANISM FOR WATER TUBULAR REABSORPTION
PASSIVE TUBULAR WATER REABSORPTION
MECHANISM FOR IONS TUBULAR REABSORPTION
PASSIVE TUBULAR SOLUTE REABSORPTION
HOW ANTIDIURETIC HORMONE AFFECTS FILTRATE
INHIBITS URINE OUTPUT
HOW ALDOSTERONE AFFECTS FILTRATE
CONTROLS REABSORPTION OF SODIUM IONS
HOW ATRIAL NATRIURETIC PEPTIDE AFFECTS FILTRATE
REDUCED BLOOD SODIUM IONS
HOW PARATHYROID HORMONE AFFECTS FILTRATE
INCREASES REABSORPTION OF CALCIUM IONS
WHAT DOES TUBULAR SECRETION DO
MOVES SELECTED SUBSTANCES FROM BLOOD INTO PERITUBULAR CAPILLARY FOR SECRETION
VASA RECTA
RETURNS SOLUTES AND WATER REABSORBED IN THE RENAL MEDULLA TO THE BLOODSTREAM WITHOUT CHANGING CONCENTRATION GRADIENT
UREA IS A RESULT OF ___
AMINO ACID CATABOLISM
URIC ACID IS A RESULT OF ___
METABOLISM OF ORGANIC BASES IN NUCELIC ACIDS
WHAT MAKES URINE YELLOW
UROCHROME PIGMENT FROM DESTRUCTION OF HEMOGLOVIN
DIFFERENCE BETWEEN RENAL CORPUSCLE AND TUBULE
CORPUSCLE: FILTERS
TUBULE: REABSORBS/SECRETES
RENAL CLEARANCE
VOLUME OF PLASMA THE KIDNEYS COMPLETELY REMOVE OVER A MINUTE TIMEFRAME
WHAT IS MICTURITION
URINATION
