| LAMINAR FLOW IS THE PARABOLIC, BULLET-SHAPED PROFILE. IT IS LAYERS OF BLOOD TRAVELING AT DIFFERENT VELOCITIES. |
|
|
Term
| WHAT CREATES TURBULENT FLOW? |
|
Definition
| THE BLOCKAGE ON THE WALLS MAKES THE LAMINAR FLOW BOUNCE INTO OTHER LAYERS OF FLUID CREATING TURBULENT FLOW WHICH IS NOISY. |
|
|
Term
| IT IS BECAUSE OF ___ FLOW THAT WE CAN MEASURE BLOOD PRESSURE. |
|
Definition
| TURBULENT. KOROTKOFF SOUNDS ARE CREATED BY TURBULENT FLOW. |
|
|
Term
| WHEN DO YOU STOP HEARING KOROTKOFF SOUNDS? |
|
Definition
| WHEN YOU GO BELOW THE DIASTOLIC BLOOD PRESSURE. WHEN THE CUFF PRESSURE FALLS BELOW DIASTOLIC BLOD PRESSURE, YOU QUIT HEARING KOROTKOFF SOUNDS BECAUSE THE BLOOD FLOW IS BACK TO LAMINAR FLOW. WHEN YOU TAKE A PERSON'S BLOOD PRESSURE, YOU ARE LISTENING FOR LAMINAR FLOW. |

|
Term
| ACCORDING TO POISEUILLE'S LAW WHAT ARE THE 3 MAJOR DETERMINANTS? |
|
Definition
| VISCOSITY, LENGTH, AND RADIUS |
|
|
Term
| ARE VISCOSITY AND RESISTANCE DIRECTLY OR INDIRECTLY PROPORTIONAL? |
|
Definition
| DIRECTLY. IF YOU INCREASE THE VISCOSITY OF THE BLOOD, THE RESISTANCE INCREASES. |
|
|
Term
| WHAT IS TOTAL RESISTANCE? |
|
Definition
| THE SUMMATION OF THE RESISTERS. |
|
|
Term
| WHAT HAPPENS TO THE TOTAL RESISTANCE IF YOU ADD ANOTHER RESISTER? |
|
Definition
|
|
Term
| DESCRIBE PARALLEL RESISTERS. |
|
Definition
| ARE CERTAIN TYPES OF RESISTERS THAT YOU CAN CHOOSE WHICH ONE TO GO THROUGH. |
|
|
Term
| HOW DO YOU CALCULATE THE TOTAL RESISTANCE OF PARALLEL RESISTERS? |
|
Definition
| IT ENDS UP BEING THE RECIPROCAL OF THE TOTAL RESISTANCE 1/RT= 1/R1 + 1/R2 + 1/R3 ETC... IF YOU ADD THEM UP YOU DON'T GET THE TOTAL RESISTANCE. YOU GET THE RECIPROCAL OF THE TOTAL RESISTANCE. |
|
|
Term
| WHAT HAPPENS IF YOU ADD A RESISTER IN PARALLEL TO A CIRCUIT? |
|
Definition
| IT DECREASE TOTAL RESISTANCE. EX. JUST LIKE ADDING ANOTHER LANE ON THE HWY. |
|
|
Term
| DOES ALL THE SYSTEMIC VASCULAR BEDS THAT INDUCE A RESISTANCE CONTRIBUTE TO THE TOTAL RESISTANCE? |
|
Definition
| YES. THEY ARE IN PARALLEL |
|
|
Term
| ARE UPPER, MIDDLE, AND LOWER LOBES IN PARALLEL OR A SERIES? |
|
Definition
|
|
Term
|
Definition
| NO. IF YOU REMOVE A SMALL RESISTER, IT WILL NOT HAVE AS MUCH OF AN EFFECT AS IF YOU TAKE OUT A LARGE RESISTER. |
|
|
Term
| WHAT 3 THINGS IN THE BODY ARE CONSIDERED IN SERIES? |
|
Definition
| ARTERIES, CAPILLARIES, AND VEINS. SO THE SYSTEMIC CIRCUIT IS IN SERIES. |
|
|
Term
| IF YOU HAVE INCREASE RESISTANCE IN THE HEPATIC CAPILLARIES WHAT HAPPENS? |
|
Definition
| YOUR PRESSURE WILL GO UP BECAUSE YOU WILL HAVE TO MAINTAIN FLOW. SO YOU WILL HAVE AN INCREASE IN THE HEPATIC PORTAL VEIN PRESSURE AND A DECREASE IN DOWNSTREAM PRESSURE. THE HEPATIC CAPILLARIES START BEHVING LIKE OUR ARTEROLES, AND INCREASE SITE OF RESISTANCE. |
|
|
Term
| THE RENAL ARTERY GIVES RISE TO THE ___ CAPILLARIES, WHICH GIVE RISE TO THE _____ CAPILLARIES BEFORE THEY EMPTY INTO THE RENAL VEIN. |
|
Definition
| GLOMERULLAR, PERITUBULAR. SO IN THE KIDNEYS, I HAVE 2 CAPILLARY BEDS IN SERIES. |
|
|
Term
| DO YOU SEE SERIES CIRCUITS AND PARALLEL CIRCUITS IN SYSTEMIC CIRCULATION? |
|
Definition
|
|
Term
| IF R = RESISTANCE, THEN WHAT IS CONDUCTANCE? WHAT DOES RESISTANCE AND CONDUCATANCE TELL US? |
|
Definition
| RESISTANCE TELLS US HOW HARD IT IS FOR SOMETHING TO FLOW. CONDUCTANCE TELLS US HOW EASY SOMETHING IS TO FLOW. |
|
|
Term
| TRUE OR FALSE? CONDUCTANCE IN A SERIES CIRCLE ADDS AS RECIPROCALS, AND CONDUCTANCE IN A PARALLEL CIRCUIT ADDS DIRECTLY. |
