Term
WHY IS THE LEFT SIDE OF THE HEART HAVE A BIGGER MUSCLE? |
|
Definition
IT'S NOT A FACTOR THAT THE LEFT VENTRICLE PUMPS MORE BLOOD OR HAS TO PUMP BLOOD TO ENTIRE BODY WHICH IS TRUE BUT NOT WHY IT'S THICKER, IT'S BECAUSE IT HAS A HIGHER AFTERLOAD. |
|
|
Term
WHAT IS THE FORMULA FOR CONTRACTILITY? |
|
Definition
CHANGE IN PRESSURE/CHANGE IN TIME |
|
|
Term
WHAT IS THE ONLY WAY WE CAN INCREASE CONTRACTILITY? |
|
Definition
|
|
Term
WHEN WE HAVE INCREASES SYMPATHETIC OUTPUT TO THE HEART, WHAT WILL THE SLOPE OF THE LEFT VENTRICULAR PRESSURE CURVE DURING ISOVOLUMETIC CONTRACTION DO? |
|
Definition
|
|
Term
|
Definition
THE INTRINSIC RHYTHM OF THE SA NODE. |
|
|
Term
DO WE HAVE A RMP WITH THE SA NODE? |
|
Definition
|
|
Term
DESCRIBE WHY THE SA NODE DOESN'T HAVE A RMP. |
|
Definition
CALLING THE SLOPE PHASE 4 WHICH IS ALSO ACLLED SPONTANEOUS DEPOLARIZATION, CAUSED BY A DECREASED K CONDUCTANCE WHICH GOES HAND IN HAND WITH INCREASE NA CONDUCTANCE. |
|
|
Term
FOR A SA NODE AS K CONDUCTANCE IS FALLING WHAT IS NA CONDUCTANCE DOING? AS THE RATIO CHANGES WHAT IS HAPPENING TO THE MEMBRANE POTENTIAL? |
|
Definition
|
|
Term
WHEN PHASE 0 IS REACHED OF THE SA NODE WHAT CATION CHANNEL IS BEING ACTIVATED? |
|
Definition
|
|
Term
IN TERMS OF THE DIFFERENT PHASES OF THE SA NODE THE HR CAN BE RELATED TO WHAT? |
|
Definition
THE RATE AT WHICH THE CONDUCTANCE RATIOS CHANGE. AND IT'S REFLECTED BY THE RATE AT WHICH THE MEMBRANE POTENTIAL CHANGES. |
|
|
Term
WHAT DOES SNS DO TO THE CONDUCTANCE RATIO? |
|
Definition
IT SPEED THE RATE AT WHICH K CONDUCTACNE FALLS OR IT SPEEDS UP THE RATE AT WHICH THE NA CONDUCTANCE RISES. |
|
|
Term
WHAT DOES THE PNS DO IN PHASE 4 OF THE SA NODE? |
|
Definition
IT DECREASES THE SLOPE, NOT ONLY DOES IT DECREASE THE SLOPE BUT IT CAN ACTUALLY DECREASE THE LOWER POINTS OF THAT. YOU END UP WITH A LONG SLOPE, ACTION POTENTIAL THEN LONG SLOPE. |
|
|
Term
DESCRIBE ELECTRICAL AND MECHANICAL ACTIVITY. |
|
Definition
ELECTRICAL ACTIVITY IS BEFORE MECHANICAL ACTIVITY. |
|
|
Term
WHAT DETERMINES THE PRELOAD? |
|
Definition
|
|
Term
WHAT SETS OUR VENOUS RETURN? |
|
Definition
THE VASCULARE RESISITANCE IN THE VENOUS SYSTEM |
|
|
Term
WHAT ARE THE 2 PARTS OF THE VASCULARE RESISITANCE? |
|
Definition
VENOCONSTRICTION AND VENODILATION./ MUSCULOSKELTAL PUMP AND THORACOABDOMINAL PUMP |
|
|
Term
WHAT HAPPENS TO VENOUS RETURN IF YOU OVERINFLATE THE LUNGS WITH POSITIVE PRESSURE? |
|
Definition
|
|
Term
WHAT DOES THE VALSALVA MANEUVER DO TO VENOUS RETURN? |
|
Definition
|
|
Term
WHAT ARE THE 2 PRINCIPLES THAT ALTER AFTERLOAD? |
|
Definition
VASOCONSTRICTION AND VASODILATION/ PLASMA VOLUME |
|
|
Term
PRELOAD AND AFTERLOAD COORELATE WITH EITHER ARTERIAL OR VENOUS? |
|
Definition
PRELOAD=VENOUS AFTERLOAD = ARTERIAL |
|
|
Term
AS WE INCREASE THE VENTRICULAR VOLUME THE VENTRICLE BECOMES LESS WHAT? |
|
Definition
|
|
Term
AT WHAT STAGE OF DIASTOLE DO WE HAVE THE HIGHEST COMPLIANCE? |
|
Definition
|
|
Term
WHAT IS THE CAUSE OF DIASTASIS? |
|
Definition
A REDUCTION IN VENTRICULAR COMPLIANCE |
|
|
Term
WHAT HAPPENS TO ACTIVE AND PASSIVE TENSION WHEN WE GO BEYONG OPTIMAL LENGTH? |
|
Definition
PASSIVE TENSION INCREASES AND ACTIVE TENSION DECREASES |
|
|
Term
WHAT IS ISOMETRIC CONTRACTION IN TERMS OF LENGTH AND TENSION? |
|
Definition
SAME LENGTH BUT INCREASE IN TENSION (CAN'T PICK UP A HEAVY OBJECT) |
|
|
Term
WHAT IS ISOTONIC CONTRACTION IN TERMS OF LENGTH AND TENSION? |
|
Definition
SAME TENSION (TONE) AND DECREASE IN LENGTH. |
|
|
Term
IN A SKELETEL MUSCLE DECRIBE ISOTONIC VS ISOMETRIC CONTRACTION. DOES THIS CONCEPT WORK FOR CARDIAC MUSCLE? |
|
Definition
IF YOU LIFT A LOAD, YOU BEGIN WITH ISOMETRIC CONTRACTION UNTIL THE TONE OF THE MUSCLE EXCEEDS THE LOAD. NO |
|
|
Term
IF YOU HAVE A SKELETAL MUSCLE AND HANG WEIGHT FROM IT, AT REST THAT WEIGHT IS GOING TO GENERATE A CERTAIN AMOUNT OF WHAT TYPE OF TENSION? |
