WHAT ARE THE FOUR (4) CHAMBERS OF THE HEART ? THE ATRIA IS THE TOP CHAMBERS & THE BOTTOM CHAMBERS ARE CALLED VENTRICLES
WHERE DOES THE BLOOD ENTERS & LEAVES THE HEART ? THE BLOOD ENTERS THE HEARTS THROUGH THE ATRIA AND LEAVES THE HEARTS FROM THE VENTRICLES
WHAT ARE THE FOUR (4) VALVES OF THE HEART ? * THE 2 ANTRIOVENTRICULAR VALVES (AV VALVES),PREVENT THE BLOOD FROM FLOWING BACKWARD THROUGH THE SYSTEM. THE SEPARATE THE ATRIA & VENTRICULES ON EACH SIDE OF THE HEART. * THE 2 SEMILUNAR VALVES (SL VALVES), SEPARATE THE VENTRICULES FROM OUTGOING VESSELS
WHAT DOES THE SEPTUM DO ? DIVIDES THE RIGHT AND LEFT SIDE OF THE HEART
THE HEART HAS HOW MANY LAYERS OF TISSUE ? THREE (3)
NAME THE THREE (3) LAYERS OF TISSUE OF THE HEART. *ENDOCARDIUM * MYOCARDIUM *PERICARDIUM
WHAT IS THE ENDORCARDIUM ? SMOOTH LAYER OF CELLS LINING THE INSIDE OF THE HEART AND FORMING THE VALVES
WHAT IS THE MYOCARDIUM ? THE THICKEST LAYER, CONSISTING OF MUSCLE TISSUE
WHAT IS THE PERICARDIUM ? DOUBLE MEMBRANE THAT COVERS THE OUTSIDE OF THE HEART, PROVIDING LUBRICATION BETWEEN THE HEART AND SURROUNDING STRUCTURES TO PREVENT TISSUE DAMAGE

HOW MANY TYPES OF BLOOD VESSELS IN THE BODY ? THREE (3)
WHAT ARE THE THREE (3) MAIN TYPES OF BLOOD VESSELS IN THE BODY ? *ARTERIES *VEINS * CAPILLARIES
FUNCTIONS OF THE ARTERIES? CARRY BLOOD AWAY FROM THE HEART
FUNCTIONS OF THE VEINS? CARRY BLOOD BACK TO THE HEART
FUNCTIONS OF THE CAPILLARIES? MICROSCOPIC VESSELS THAT CARRY BLOOD BETWEEN THE ARTERIAL & VENOUS VESSELS
NAME OF THE LARGEST ARTERY IN THE BODY ? AORTA
ARTERIES HAVE A LAYER OF WHAT ? MUSCULAR LAYER OF TISSUE THAT HELPS PUMP BLOOD WHILE VEINS ARE MUCH THINNER
WHAT ARE SOME METHODS TO ASSESS THE HEART CONDITION ? * MEASURING PULSE AND BLOOD PRESSURE * LISTENING TO HEART SOUNDS * DETERMINING CARDIAC OUTPUT * INSERTING A CARDIAC CATHETER * USING ECHOCARDIOGRAPHY
EVERY TIME YOUR HEART BEATS, BLOOD SURGES AGAINST THE WALLS OF THE ARTERIES, THAT IS YOUR ___________. PULSE
WHAT ARE THE EIGHT (8) DIFFERENT PLACES THAT YOU CAN TAKE YOUR PULSE FROM ? * RADIAL ARTERY IN THE WRIST * LARGE CAROTID ARTERY IN THE THROAT * BRACHIAL ARTERY * TEMPORAL ARTERY * POPLITEAL ARTERY * POSTERIOR TIBAL ARTERY * PEDAL ARTERY * FEMORAL ARTERY
DESCRIBE "BLOOD PRESSURE" IS THE FORCE OF THE BLOOD AGAINST THE WALLS OF THE ARTERIES
DESCRIBE "SYSTOLIC BLOOD PRESSURE" & "DIASTOLIC BLOOD PRESSURE" SYSTOLIC BLOOD PRESSURE IS WHEN THE VENTRICULES CONTRACT WHILE THE DIASTOLIC BLOOD PRESSURE OCCURS WHEN THE VENTRICULES RELAX
WHAT IS CONSIDER A HEALTHY SYSTOLIC PRESSURE ? LESS THAN 140 AND MORE THAN 90
WHAT IS CONSIDER A HEALTHY DIASTOLIC PRESSURE ? LESS THAN 100
THE "LUB-DUP" SOUND OF THE HEART CAN BE HEARD USING WHAT ? A STETHOSCOPE
CHARACTERISTIC SOUNDS OF THE HEART RESULT FROM WHAT ? THE OPENING & CLOSING OF THE VALVES IN THE HEART AS THE BLOOD IS PUMPED FROM THE ATRIA TO THE VENTRICLES AND THEN TO THE LUNGS AND THE THROUGHOUT THE BODY
WHAT IS A HEART RATE ? HEART REGULATES THE RATE AT WHICH THE BLOOD CIRCULATES TO THE TISSUES
WHAT IS A STROKE VOLUME ? THE AMOUNT OF BLOOD CONTAINED IN THE VENTRICLES.
THE BLOOD IS PUMPED INTO THE ARTERIES WITH EACH _________. HEARTBEAT
