BLOOD PRESSURE REGULATION IN KIDNEYS Flashcards
IN RELATION TO SPINAL LEVELS WHERE ARE THE KIDNEYS LOCATED
T12-L3
HOW MUCH BLOOD PER MIN DO THE KIDNEYS FILTER
1.2L
WHAT ARE THE THREE MAJ PROCESSES OF URINE FORMATION
GLOMERULAR FILTRATION, TUBULAR REABSORPTION, TUBULAR SECRETION
WHAT IS THE ARTERIAL SUPPLY TO THE KINDEYS
RENAL ARTERIES
WHAT PLAYS AN IMPORTANT ROLE IN LONG TERM BLOOD PRESSURE REGULATION
NEPHRONS
WHAT SYSTEM IS CRITICALLY INVOLVED IN BLOOD VOLUME, ELECTROLYTE BALANCE, AND SYSTEMIC VASCULAR RESISTANCE
RENIN-ANGIOTENSIN-ALDOSTERONE SYSTEM
WHAT IS THE ROLE OF THE RENIN-ANGIOTENSIN-ALDOSTERONE SYSTEM
MAINTAIN BLOOD VOLUME/PRESSURE, ELECTROLYTE BALANCE AND SYSTEMIC VASCULAR RESISTANCE
WHERE DOES HORMONE REGULATED REABSORPTION OCCUR
IN THE DISTAL CONVOLUTED TUBULE AND CONVOLUTED DUCTS
WHAT RELAEASES ANTIDIURETIC HORMONE
POSTERIOR PITUATARY GLAND
WHEN WOULD THE POSTERIOR PITUATARY GLAND RELEASE ADH
IN RESPONSE TO DEHYDRATION (INCREASED EXTRA CELLULAR FLUID OSMOLARITY)
HOW DOES ANTIDIURETIC HORMONE WORK
INCREASES THE PERMEABILITY OF THE D.C.T AND C.D TO WATER, BY INSERTING AQUAPORINS INTO THE APICAL MEMBRANE OF TUBULE CELLS SO THAT WATER IS REABSORBED BACK INTO THE BODIES SYSTEM RATHER THAN BEING EXCRETED
IS ADH RELEASE REDUCED IN AN OVERHYDRATED STATE
YES
WHAT INHIBITS THE RELASE OF ADH
CAFFEINE AND ALCOHOL
WHAT STRUCTURES RELEASES ALDOSTERONE
RELEASED BY THE ADRENAL GLAND
WHAT STIMULUS INITIATES THE RELEASE OF ALDOSTERONE
LOW BLOOD PRESSURE
