Flash Cards from Lecture - Urinary
RENAL CORTEX
MOST SUPERFICIAL REGION; DARK BROWN; MANY BLOOD VESSELS
RENAL MEDULLA
MIDDLE REGION; CONTAINS RENAL PYRAMID; AKA MEDULLARY PYRAMIDS
MEDULLARY PYRAMID
RENAL PYRAMID; CONTAIN LOOPING TUBULES OF NEPHRONS (AVG 7-11) ALSO CALLED LOBES; DARK CONE SHAPED; CONTAIN URINE COLLECTING TUBULES
RENAL COLUMN
PART OF RENAL CORTEX; SEPARATE RENAL PYRAMIDS FROM EACH OTHER; INWARD EXTENSIONS OF CORTEX; CONTAIN GLOMERULA
RENAL PELVIS
BASIN FOR COLLECTING URING; INNERMOST REGION OF KIDNEY; MAJOR CALYCES DRAIN INTO IT
MAJOR/MINOR CALYCES
FLUID FROM RENAL PAPILLA DRAIN INTO MINOR THEN INTO MAJOR CALYCES THEN INTO RENAL PELVIS
RENAL PAPILLA
At apex of renal pyramid; collecting ducts pass through; where urine flows into minor calyces
URETER
FIRST PART OF URINARY TRACT; LINED WITH TRANSISITIONAL EPITHELIUM; WALLS ARE SMOOTH MUSCLE FOR PERSITALSIS females is is short in males 4x longer 3 parts in males prostatic prostate gland) membranous c s pelvic diaphragm spongy( penis)
URINARY BLADDER
URETERS DRAIN INTO BLADDER VIA URETERAL ORIFICES; TRANSITIONAL EPITHELIUM; SMOOTH MUSCLE SOMETIMES CALLED DETRUSOR MUSCLE; 3 layers of muscle?? End narrows to form internal urethral sphincter
URETHRA
FINAL ORGAN OF URINARY SYSTEM;
NEPHRON
BLOOD FILTERING STRUCTURES OF KIDNEY; 2 PARTS RENAL CORPUSCLE AND RENAL TUBULE
GLOMERULUS
BALL OF LOOPING CAPILLARIES; NOT PRIMARY SITE OF GAS/NUTRIENT EXCHANGE
PERITUBULAR CAPILLARIES
EFFERENT ARTERIOLE BRANCHES FORM THIS; SURROUND TUBULES OF NEPHRON; DIFFUSION OF 02 AND CO2/NUTRIENTS DRAIN INTO INTERLOBULAR VEINS
PROXIMAL CONVULUTED TUBE
FIRST PART OF RENAL TUBE; TOUCHES GLOMERULUS
NEPHRON LOOP
PART OF RENAL TUBE
DISTAL CONVOLUTED TUBE
LAST PART OF RENAL TUBE, TOUCHES COLLECTION DUCT
CORTICAL COLLECTING DUCT
COLLECTING SYSTEM; NOT PART OF NEPHRON LOOP; IN RENAL CORTEX
MEDULLARY COLLECTING DUCT
COLLECTING SYSTEM; NOT PART OF NEPHRON LOOP; IN MEDULLA CORTEX
PAPILLARY DUCT
MEDULLARY COLLECTION DUCTS ENLARGE INTO THESE; EMPTY INTO MINOR CALYCES
RENAL CORPUSCLE 2 PARTS
GLOMERULUS AND ??
2 LAYERS OF GLOMERULUS CAPSULE
OUTER PARIETAL LAYER AND INNER VISCERAL LAYER THAT CONTAINS PODOCYTES
PODOCYTES
??
RENAL TUBE IS ALSO KNOW AS SLANG TERM
PLUMBING FOR THE KIDNEY
3 PARTS OF RENAL TUBE
PROXIMAL CONVOLUTED TUBULE; DESCENDING AND ASCENDING LIMBS OF NEPHRON LOOP; DISTAL CONVOLUTED TUBULE
WHERE IS THE MAJORITY OF THE RENAL TUBULE LOCATED
IN RENAL CORTEX; ONLY NEPHRON LOOPS SLIP DOWN INTO MEDULLARY
NEPHRON IS MADE UP OF 2 PARTS
RENAL CORPUS AND RENAL TUBULE : DBL CHECK THIS
RENAL CORPUS 2 PARTS
GLOMERULUS AND GLOMERULAR CAPSULE
GLOMERULUS
BALL OF LOOPING CAPILLARIES
WHAT DO THE KIDNEYS FILTER OUT OF THE BLOOD
TOXINS, METABOLLIC WASTES; EXCESS H20 AND IONS
KIDNEYS FILTER WHAT
BLOOD
WHAT 3 NITROGENOUS WASTES FROM BLOOD DO THE KIDNEYS FILTER
UREA; URIC ACID; CREATINE
UREA COMES FROM
PROTEIN BREAKDOWN
URIC ACID COMES FROM
ALMOST INSOLUBLE; FROM PURIES (BEER/NUTS/BEANS)
CREATINE COMES FROM
PRODUCT OF METABOLISM
MAIN FUNCTIONS OF URINARY SYSTEM
FILTER BLOOD; REMOVE NITROGENOUS AND OTHER WASTES; REGULATE H20 AND ELECTROLYTES
KIDNEY AS A WHOLE IS WHAT TYPE OF ORGAN
A DIURETIC ORGAN; MEANING IT LOSES H20
WHAT HORMONE TELLS BODY TO HOLD ONTO H20
ADH ANTIDIURETIC HORMONE - MADE BY HYPOTHALAMUS AND STORED IN NEUROHYPOPHYSIS (POSTERIOR PITUITARY); BALANCES H20
WHAT HORMONE TELLS BODY TO RELEASE H20
ALDOSTERONE (STEROID) FROM ADRENAL CORTEX; BALANCES ELECTROLYTES
WHAT IS PROTECTING THE KIDNEYS POSTERIOLY
OBLIQUES; LATISIMUS DORSI; GLUTES
KIDNEYS ARE WHAT TYPE OF FANCY WORD POSITIONING
RETROPERITONEAL
RETROPERITONEAL MEANS
BEHIND THE PERITONEAL CAVITY
WHAT 3 LAYERS ARE THE KIDNEYS ENCASED IN
RENAL FASCIA; ADIPOSE CAPSULE; RENAL CAPSULE
RENAL FASCIA
??
ADIPOSE CAPSULE
??
RENAL CAPSULE
??
WHAT IS THE LOCATION, POSITIONING AND APPEARANCE OF EACH KIDNEY
RETROPERITONEAL - LOCATED BEHING THE PERITONEAL CAVITY; SUPERIOR PORTION OF KIDNEY IS LOCATED IN FRONT OF LOWEST RIB BONE/ CHECK THE RIB PART WITH TEACH
WHERE IS THE HILUS LOCATED AND WHAT DOES IT LOOK LIKE
??
2 MAJOR REGIONS OF THE KIDNEY
RENAL CORTEX (OUTER REGION); MEDULLA (INNER REGION)
HOW MANY LOBES DO HUMAN KIDNEYS HAVE
IS THIS THE MEDULLARY PYRAMID????
WHAT DOES THE LOBE CONSIST OF
?? ASK IS THIS THE MEDULLARY PYRAMID
RENAL PELVIS (BASIN)
SERVES AS A BASIN FOR COLLECTING URINE FROM MAJOR CALYCES
MAJOR AND MINOR CALYCES
FLUID FROM RENAL PAPILLA DRAIN INTO MINOR CALYCES THEN TO MAJOR CALYCES AND THEN TO RENAL PELVIS/BASIN
WHAT ENTERS THROUGH RENAL ARTERY
OXYGENATED UNFILTERED BLOOD (IE BLOOD/WASTER/H20)
WHAT LEAVES THROUGH RENAL VEIN
DEOXYGENATED FILTERED BLOOD (IE BLOOD WITHOUT WASTE/EXCESS WATER)
WHAT LEAVES THROUGH THE URETHRA
URINE (PROCESSED BLOOD PLASMA) (IE( EXCESS H20 AND TOXIC WASTE IN THE FORM OF URINE)
3 KEY ENTRY POINTS
MAY HAVE MISHEARD BUT CHECK - RENAL ARTERY IS ONLY WAY INTO KIDNEY
WHAT ARE THE MAIN STRUCTURES OF THE URINARY SYSTEM
KIDNEY; URETER; BLADDER; URETHRA
WHAT ARE WAYS TO TELL THE IVC FROM THE ABDOMINAL AORTA
AORTA HAS MANY MORE BRANCHES COMING OFF IT THAN IVC
RENAL ARTERY IS CARRYING WHAT
OXYGENATED BLOOD AND UNFILTERED
RENAL VEIN IS CARRYING
DEOXYGENATED FILTERED BLOOD
URETER CARRIES WHAT
WASTES GO INTO URETEER (CALLED URINE) AND EXCESS H20
WHICH SIDE OF THE BODY IS THE PULMONARY CIRCUIT
RIGHT SIDE; CALLED PULMONARY BECAUSE BLOOD IS FLOWING TO THE LUNGS (PUMONARY)
