INSENSIBLE FLUID LOSSES OCCURS WHERE
|
THRU THE SKIN AND LUNGS. THEY R CALLED INSENSIBLE CAUSE THEY CAN'T BE SEEN OR MEASURED
|
|
|
DESCRIBE A ISOTONIC SOLUTIONS
|
SOLUTE THAT HAS THE SAME CONCENTRATION AS ANOTHER SOLUTION, FLUID DOESNT SHIFT BETWEEN ISOTONIC SOLUTIONS CAUSE THEY'RE EQUALLY CONCENTRATED AND ALREADY IN BALANCE
|
|
|
DESCRIBE A HYPORTONIC SOLUTION
|
THE SOLUTE CONCENTRATION OF A HYPOTONIC SOLUTION IS LESS THAN THAT OF SERUM. THEREFORE IT SHIFTS OUT OF THE INTRAVASCULAR COMPART AFTER ADMINISTRATION
|
|
|
DESCRIVE A HYPERTONIC SOLUTION
|
THE SOLUTE CONCENTRATION OF A HYPERTONIC SOLUTION IS HIGHER THAN THAT OF SERUM, THEREFORE IT DRAWS FLUID INTO THE INTRAVASCULAR SPACE AFTER ADMINISTRAION
|
|
|
HOW DOES SOLUTES MOVE THRU THE BODY
|
THRU THE INTRACELLULAR, INTERSTITIAL AND INTRAVASCULARE COMPARTMENTS BY CROSSING SEMIPERMABLE MEMBRANES THRU THE CELLS AND CAPILLARIES
|
|
|
WHAT IS DIFFUSION
|
SOLUTES MOVING FROM AREAS OF HIGHER CONCENTRATION TO AREAS OF LOWER CONCENTRATION UNTIL BOTH ARE EQUAL AND REQUIRES NO ENERGY
|
|
|
WHAT IS ACTIVE TRANSPORT
|
SOLUTES MOVE FROM AN AREA OF LOWER CONCENTRATION TO AN AREA OF HIGHER CONCENTRATION WHICH REQUIRES ENERGY FROM A MOLECULE CALLED ADENOSINE TRIPHOSPHATE (ATP)
|
|
|
WHAT IS OSMOSIS
|
FLUIDS MOVES PASSIVELY FROM AREAS WITH MORE FLUID (AND FEWER SOLUTES) TO AREAS WITH LESS FLUID (AND MORE SOLUTES)
REMEMBER IN OSMOSIS FLUID MOVES IN DIFFUSION SOLUTES MOVE |
|
|
WHAT IS HYDROSTATIC PRESSURE
|
THE PRESSURE OF BLOOD PUSHING AGAINST CAPILLARY WALLS FORCING FLUIDS AND SOLUTES OUT INTO THE INTERSTITIAL FLUID
|
|
|
WHAT IS PLASMA COLLOID OSMOTIC PRESSURE
|
THE PULLING FORCE OF ALBUMIN THAT ACTS AS A WATER MAGNET TO ATTRACT AND HOLD WATER INSIDE VESSELS
|
|
|
WHAT HAPPENS WHEN HYROSTATIC PRESSURE EXCEEDS PLASM COLLOID OSMOTIC PRESSURE
|
WATER & SOLUTES CAN LEAVE THE CAPILLARIES AND ENTER THE INTERSTITIAL FLUID
|
|
|
WHAT HAPPENS WHEN HYDROSTATIC PRESSURE IS LESS THAN PLASMA COLLOID OSMOTIC PRESSURE
|
WATER AND SOLUTES RETURN TO THE CAPILLARIES
|
|
|
WHAT ARE THE KIDNEYS JOB WHEN MAINTAINING FLUID BALANCE
|
FILTERING BLOOD (180L DAILY) PRODUCE URINE (1-2L DAILY)
CONSERVES WATER OR EXCRETES EXCESS FLUID TO MAINTAIN BALANCE |
|
|
WHAT DOES THE ANTIDIURETIC HORMONE WORK
|
THE ADH REGULATES FLUID BALANCE BY RESTORING BLOOD VOLUME BY REDUCING DIURESIS AND INCREASING WATER RETENTION
|
|
|
WHAT ARE THE STEPS OF THE ADH
|
THE HYPOTHALAMUS SENSES LOW BLOOD VOL. AND INCREASE SERUM OSMOLALITY & SIGNALS THE PITUITARY GLAND, THE PIT GLAND SECRETES ADH IN THE BLOODSTREAM, ADH CAUSE THE KIDNEY TO RETAIN WATER, WATER RETENTION BOOSTS BLOOD VOLUME & DECREASES SERUM OSMOLALIYY`
