CH- 25 FINAL
URINARY SYSTEM
| Question | Answer |
|---|---|
| THE MECHANISM THAT ESTABLISHES THE MEDULLARY OSMOTIC GRADIENT DEPENDS MOST ON THE PERMEABILITY PROPERTIES OF THE | LOOP OF HENLE |
| URINE PASSES THROUGH THE | PELVIS OF THE KIDNEY TO URETER TO BLADDER THEN TO URETHRA |
| WHAT IS NOT ASSOCIATED WITH THE RENAL CORPUSCLE | A VASA RECTOR |
| AN INCREASE IN THE PERMEABILITY OF THE CELLS OF THE COLLECTING TUBULE TO WATER IS DUE TO A | INCREASE IN PRODUCTION OF ADH |
| THE URINARY BLADDER IS COMPOSED OF ________ EPITHELIUM | TRANSITIONAL |
| THE KIDNEYS ARE STIMULATED TO PRODUCE RENIN | BY DECREASE IN THE BLOOD PRESSURE |
| WHAT IS NOT A FUNCTION OF THE URINARY SYSTEM | ELIMINATES SOLID, UNDIGESTED WASTES AND EXCRETES CARBON DIOXIDE WATER SALTS AND HEAT |
| WHICH GLAND SITS ATOP THE KIDNEY | ADRENAL |
| THE ______ ARTERY LIES ON THE BOUNDRY BETWEEN THE CORTEX AND MEDULLA OF THE KIDNEY | ACRUATE |
| THE GLOMERULUS DIFFERS FROM OTHER CAPILLARIES IN THE BODY THAT IS | IS DRAINED BY EFFERENT ARTERIOLE |
| THE DESCENDING LIMB OF THE LOOP OF HENLE | CONTAINS FLUID THAT BECOMES MORE CONCENTRATED AS IT MOVES DOWN INTO THE MEDULLA |
| WHAT IS THE CORRECT STATEMENT ABOUT THE URETERS | THE URETERS ARE CAPABLE 0F PERISTALSIS LIKE THAT OF THE GASTROINTESTINAL TRACT |
| THE FATTY TISSUE SURROUNDING THE KIDNEYS IS IMPORTANT BECAUSE IT | STABILIZES THE POSITION OF THE KIDNEYS BY HOLDING THEM INTO THEIR NORMAL POSITION |
| THE RENAL CORPUSCLE IS MADE UP OF | BOWMANS CAPSULE AND GLOMERLUS |
| THE FUNCTIONAL AND STRUCTURAL UNIT OF THE KIDNEYS IS THE | NEPHRON |
| THE JUXTOGLOMERULAR APPARATUS IS RESPONSIBLE FOR | REGULATING THE RATE OF FILTRATE FORMATION AND CONTROLLING SYSTEMIC BLOOD PRESSURE |
| THE CHIEF FORCE PUSHING WATER AND SOLUTES OUT OF THE BLOOD ACROSS THE FILTRATION MEMBRANE IS ________ | GLOMERULAR HYDROSTATIC PRESSURE (GLOMERULAR BLOOD PRESSURE) |
| WHAT STATEMENT DESCRIBES THE HISTOLOGY OF THE URETERS | THEY ARE TRILAYERED (MUCOSA,MUSCULARIS,ADVENTITIA) |
| TRUE OR FALSE: THE MALE URETHRA SERVES BOTH THE URINARY AND REPRODUCTIVE SYSTEMS AT THE SAME TIME | TRUE |
| WHAT ACTS AS A TRIGGER FOR THE INITIATION OF MICTURITION | THE STRETCHING OF THE BLADDER WALL |
| THE FILTRATION MEMBRANE DOES NOT INCLUDE | RENAL FASCIA |
| THE MECHANISM OF WATER REABSORBTION BY THE RENAL TUBULE IS | OSMOSIS |
| MOST ELECTROLYTE REABSORPTION BY THE RENAL TUBULES IS | HORMONALLY CONTROLLED IN DISTAL TUBULE SEGMENTS |
| THE MACULA DENSA CELLS RESPOND TO | CHANGES IN SOLUTE CONTENT OF THE FILTRATE |
| WHAT IS NOT REABSORBED BY THE PROXIMAL CONVOLUTED TUBULE | CREATININE |
| THE FLUID THAT GLOMERULAR (BOWMANS) CAPSULE IS SIMILAR TO PLASMA EXCEPT THAT IT DOES NOT CONTAIN A SIGNIFICANT AMOUNT OF | PLASMA PROTEIN |
| ALCOHOL ACTS AS A DIURETIC BECAUSE IT | INHIBITS THE RELEASE OF ADH |
| THE FUNCTION OF ANGIOTENSIN II IS TO | CONSTRICT ARTERIOLES AND INCREASE BLOOD PRESSURE |
| A DISEASE CAUSED BY INADEQUATE SECRETION OF ANTIDIURETIC HORMONE (ADH) BY THE PITUITARY GLAND WITH SYMPTOMS OF POLYURIA IS | DIABETES INSIPIDUS |
| AN IMPORTANT CHARACTERISTIC OF URINE IS ITS SPECIFIC GRAVITY OR DENSITY. WHICH SHOULD BE | 1.001-1.035 |
| PLACE IN THE CORRECT SEQUENCE FROM THE FORMATION OF A DROP OF URINE TO ITS ELIMINATION FROM THE BODY | NEPHRON,COLLECTING DUCT, MINOR CALYX, MAJOR CALYX, URETER, URETHRA |
| WHAT IS A CORRECT STATEMENT ABOUT NEPHRONS | THE PARIETAL LAYER OF THE GLOMERULAR CAPSULE IS SIMPLE SQUAMOUS EPITHELIUM |
| WHAT WOULD HAPPEN IF THE CAPSULAR HYDROSTATIC PRESSURE WERE INCREASED ABOVE NORMAL | NET FILTRATION WOULD DECREASE |
| WHAT IS NOT PART OF THE JUXTAGLOMERULAR APPARATUS | PODOCYTE CELLS |
| TUBULAR REABSORPTION______ | BY ACTIVE MECHANISMS USUALLY INVOLVES MOVEMENT AGAINST AN ELECTRICAL AND OR CHEMICAL GRADIENT |
| WHAT WOULD NOT BE A REASON SUBSTANCES ARE EITHER NOT REABSORBED OR ARE INCOMPLETELY REABSORBED FROM THE NEPHRON | THEY ARE EXTREMELY COMPLEX MOLECULES |
| REABSORPTION OF HIGH LEVELS OF GLUCOSE AND AMINO ACIDS IN THE FILTRATE IS ACCOMPLISHED BY | SECONDARY ACTIVE TRANSPORT |
| WHAT IS A FUNCTION OF THE LOOP OF HENLE | FORM A LARGE VOLUME OF VERY DILUTE URINE OR A SMALL VOLUME OF VERY CONCENTRATED URINE |
| FETAL KIDNEYS DO NOT HAVE TO WORK VERY HARD BECAUSE | THE PLACENTA ALLOWS THE MOTHERS URINARY SYSTEM TO CLEAR WASTE FROM FETAL BLOOD |
| WHAT BEST DESCRIBES KIDNEY FUNCTION IN OLDER ADULTS (70YRS OR OLDER) | KIDNEY FUNCTION DECREASES DUE TO KIDNEY ATROPHY |
| THE FACTOR FAVORING FILTRATE FORMATION AT THE GLOMERULUS IS TH | GLOMERULAR HYDROSTATIC PRESSURE |
| IF THE Tm FOR A PARTICULAR AMINO ACID IS 120mg/100ml AND THE CONCENTRATION OF THAT AMINO ACID IN THE BLOOD IS 230mg/100ml THE AMINO ACID WILL____ | APPEAR IN THE URINE |
| IF ONE SAYS THE CLEARANCE VALUE OF GLUCOSE IS ZERO WHAT DOES THIS MEAN | NORMALLY ALL THE GLUCOSE IS REABSORBED |
| EXCRETION OF DILUTE URINE REQUIRES | IMPERMEABILITY OF THE COLLECTING TUBULE TO WATER |
| WHAT IS NOT A METHOD BY WHICH CELLS OF THE RENAL TUBULES CAN RAISE BLOOD PH | BY SECRETING SODIUM IONS |
| IN THE ASCENDING LIMB OF THE LOOP OF HENLE THE | THICK SEGMENT MOVES IONS OUT INTO INTERSTITIAL SPACES FOR REABSORPTION |
| WHAT IS A CORRECT STATEMENT ABOUT URINARY SYSTEM DEVELOPMENT | KIDNEYS DEVELOP FROM UROGENITAL RIDGES |
| WHAT DOES NOT DESCRIBE THE IMPORTANCE OF TUBULAR SECRETION | RIDDING THE BODY OF BICARBONATE IONS |
| TRUE OR FALSE: REABSORPTION OF WATER IS HORMONALLY CONTROLLED | TRUE |
| WHAT IS THE FUNCTION OF THE JUXTAGLOMERULAR APPARATUS | TO HELP REGULATE BLOOD PRESSURE AND THE RATE OF BLOOD FILTRATION BY THE KIDNEYS |

| WHAT HORMONE IS RESPONSIBLE FOR FACULTATIVE WATER REABSORPTION | ADH |
| WHAT IS NOT GLOMERULAR FILTRATION CONTROL METHOD | ELECTROLYTE LEVELS |
| WHAT IS THE MOST IMPORTANT HORMONE REGULATORS OF ELECTROLYTE REABSORPTION AND SECRETION | ANGIOTENSISN II AND ALDOSTERONE |
| WHICH CELLS OF THE KIDNEY ARE CHEMORECEPTORS THAT RESPOND TO CHANGES IN SOLUTE CONTENT OF THE FILTRATE | MACULA DENSA CELLS |
| THE CAPILLARY BED THAT SURROUNDS THE DESCENDING AND ASCENDING LOOP OF HENLE OF THE JUXTAMEDULLARY NEPHRONS IS CALLED THE | VASA RECTA |
| URINE CRYSTALS IN THE RENAL PELVIS ARE CALLED | RENAL CALCULI |
| THE NEED TO GET UP IN THE MIDDLE OF THE NIGHT TO URINATE IS CALLED | NOCTURIA |
