WHAT IS THE URINARY SYSTEM?
THE GROUP OD ORGANS THAT PRODUCES URINE, MAINTAINING FLUID AND ELECTROLYTE BALANCE FOR THE BODY.
WHAT IS URINE?
THE FLUID MADE BY THE KIDNEY AND ELIMINATED FROM THE BODY
WHAT IS UREA?
WASTE DERIVED FROM AMMONIA PRODUCED THROUGH PROTEIN METABOLISM.
WHAT ARE THE FLANKS?
THE PART OF THE BODY BELOW THE RIBS AND ABOVE THE HIP BONES.
WHAT IS THE NEPHRON?
A MICROSCOPIC STRUCTURE WITHIN THE KIDNEY THAT PRODUCES URINE.
WHAT IS THE HILUM?
THE NOTCHED PART OF THE KIDNEY WHERE THE URETER AND OTHER STRUCTURES JOIN KIDNEY TISSUE.
HOW MUSH URINE IS PRODUCED IN A NORMAL ADULT?
1CC/KG PER HOUR. 600CC/DAY
WHAT IS THE CORTEX?
THE OUTER TISSUE OF AN ORGAN SUCH AS THE KIDNEY
WHAT ARE THE PYRAMIDS?
THE VISIBLE TISSUE STRUCTURES WITHIN THE MEDULLA OF THE KIDNEY.
WHAT IS THE PAPILLA?
THE TIP OF A PYRAMID; IT JUTS INTO THE HOLLOW SPACE OF THE KIDNEY.
WHAT IS THE RENAL PELVIS?
THE HOLLOW SPACE OF THE KIDNEY THAT JUNCTIONS WITH A URETER.
WHAT IS THE BOWMANS CAPSULE?
THE HOLLOW, CUP-SHAPED FIRST PART OF THE NEPHRON TUBULE.
WHAT IS THE GLOMERULUS?
A TUFT OF CAPILLARIES FROM WHICH BLOOD IS FILTERED INTO A NEPHRON.
WHAT IS THE PROXIMAL TUBULE?
THE PART ID THE TUBULE BEYOND BOWMANS CAPSULE
WHAT IS THE DECENDING LOOP OF HENLE?
THE PART OF THE TUBULE BEOND THE PROXOMAL TUBULE
WHAT IS GLOMERULAR FILTRATION?
THE REMOVAL OF WATER AND OTHER ELEMENTS FROM THE BLOOD IN THE NEPHRONE TUBULE.
WHAT IS REABSORPTION?
THE MOVEMENT OF A SUBSTANCE FROM A NEPHRON TUBULE BACK INTO THE BLOOD.
WHAT IS SECRETION?
THE MOVEMENT OF A SUBSTANCE FROM THE BLOOD INTO A NEPHRON TUBULE.
WHAT IS FILTRATE?
THE FLUID PRODUCED IN BOWMANS CAPSULE BY FILTRATION OF BLOOD.
WHAT IS THE GLOMERULAR FILTRATION RATE?
THE VOLUME PER DAY AT WHICH BLOOD IS FILTERED THROUGH CAPILLARIES OF THE GLOMERULERS.
WHAT IS SIMPLE DIFFUSION?
THE RANDOM MOTION OF MOLECULES FROM AND AREA OF HIGH CONCENTRATION TO AND AREA OF LOWER CONCENTRATION
WHAT IS OSMOSIS?
THE DIFFUSION PATTERN OF WATER IN WHICH MOLECULES MOVE TO EQUALIZE CONCENTRATION ON BOTH SIDES OF A MEMBRANE.
WHAT IS OSMOLARITY?
THE MEASURE OF A SUBSTANCES CONCENTRATION IN WATER.
WHAT IS HYPEROSMOLAR?
A SOLUTION THE HAS A CONCENTRATION OF THE SUBSTANCE GREATER THAN THAT OF A SECOND SOLUTION
WHAT IS HYPO OSMOLAR?
A SOLUTION THAT HAS A CONCENTRATION OF THE SUBSTANCE LOWER THAN THAT OF A SECOND SOLUTION.
WHAT IS FACILLITATED DIFFUSION?
A FORM OF MOLECULAR DIFFUSION IN WHICH A MOLECULE SPECIFIC CARRIER IN A CELL MEMBRANE SPEEDS THE MOLECULES MOVEMENT FROM A REGION OF HIGHER CONCENTRATION TO ONE OF LOWER CONCENTRATION
WHAT ARE THE 3 PRIMARY FUNCTIONS OF THE KIDNEYS?
FORM URINE
CONTROL ARTERIAL BLOOD PRESSURE
REGULATING ERYTHROCYTE DEVELOPMENT
WHAT IS CREATININE?
A WASTE PRODUCT CAUSED BY METABOLISM WITHIN MUSCLE CELLS.
WHAT IS BUN?
BLOOD UREA NITROGEN TEST. DIRECTLY MEASURES BLOOD CONCENTRATION OF UREA AND IS AN INDIRECT INDICATOR OF GFR.
WHAT IS RENIN?
AN ENZYME PRODUCED BY KIDNEY CELLS THAT PLAYS A KEY ROLE IN CONTROLLING ARTERIAL BLOOD PRESSURE?
WHAT IS ERYTHOPOITIN?
A HORMONE PRODUCED BY KIDNEY CELLS THAT STIMULATED MATURATION OF RED BLOOD CELLS.
WHAT IS OSMOTIC DIURESIS?
GREATLY INCREASED URINATION AND DEHYDRATION THAT RESULTS WHEN HIGH LEVELS OF GLUCOSE CANNOT NE REABSORBED INTO THE BLOOD FROM THE KIDNEY TUBULES AND THE OSMOTIC PRESSURE OF THE GLUCOSE IN THE TUBULES ALSO PREVENTS WATER REABSORPTION.
