| BLOOD FLOOD THROUGH THE HEART | BEGINS IN THE RIGHT ATRIUM, WHICH RECEIVES DEOXYGENATED BLOOD FROM THE INFERIOR AND SUPERIOR VENAE CAVAE. THE ATRIA CONTRACT, AND BLOOD PASSES THROUGH THE TRICUSPID VALVE INTO THE RIGHT VENTRICLE; THE VENTRICLES CONTRACT, AND THE BLOOD PASSES FROM THE RIGHT VENTRICLE TO THE LUNGS VIA THE PULMONARY ARTERY. OXYGENATION OCCURS IN THE LUNGS, AND THE BLOOD RETURNS TO THE LEFT ATRIA THROUGH THE PULMONARY VEINS; THE ANTRIA CONTRACT, AND BLOOD PASSES THROUGH THE MITRAL (BISCUPID) VALVE INTO THE LEFT VENTRICLE; THE VENTRICLES CONTRACT, AND OXYGEN-RICH BLOOD IS SENT OUT TO THE BODY THROUGH THE AORTA. |
| DYSPNEA | DIFFICULT OR PAINFUL BREATHING |
| ORTHOPNEA | CONDITION IN WHICH AN INDIVIDUAL MUST SIT OR STAND TO BREATHE COMFORTABLY |
| TACHYCARDIA | RAPID BUT REGULAR HEART RATE EXCEEDING 100 BEATS PER MINUTE |
| BRADYCARDIA | A SLOW HEARTBEAT, A PULSE BELOW 60 BEATS PER MINUTE |
| FIVE TYPES OF SHOCK | CARDIOGENIC, HYPOVOLEMIC, NEUROGENIC, ANAPHYLACTIC, (SEPTIC, SEPTICEMIA) |
| PATHWAY OF BLOOD FLOW THROUGH THE HEART | THE SUPERIOR AND INFERIOR VENA CAVAE BRING OXYGEN POOR-BLOOD THAT HAS PASSED THROUGH ALL OF THE BODY TO THE RIGHT ATRIUM, THE RIGHT ATRIUM CONTRACTS TO FORCE BLOOD THROUGH THE TRICUSPSID VALVE INTO THE RIGHT VENTRICLE, AS THE RIGHT VENTRICLE CONTRACTS TO PUMP THE OXYGEN-POOR BLOOD THROUGH THE PULMONARY VALVE INTO THE PULMONARY ARTERY, AN THEN ENTERS THE LUNGS CAPILLARIES WHERE LOOSES-EXPELLED-EXHALED CARBON DIOXIDE CO2, AT THE SAME TIME OXYGEN ENTERS THE CAPILLARIES OF THE LUNGS AND IS BROUGHT BACK TO THE HEART VIA THE PULMONARY VEINS. THE NEWLY OXYGENATED BLOOD ENTERS THE LEFT ATRIUM AND THE WALLS OF THE LEFT ATRIUM CONTRACT TO FORCE BLOOD THROUGH THE MITRAL VALVE INTO THE LEFT VENTRICLE, THE LEFT VENTRICLE PROPELS THE BLOOD THROUGH THE AORTIC VALVE INTO THE AORTA SO BLOOD TRAVELS TO ALL PARTS OF THE BODY. THE AORTIC VALVE CLOSES TO PREVENT RETURN OF AORTIC BLOOD TO THE LEFT VENTRICLE. |
| SA NODE | SINOATRIAL NODE-PACEMAKER OF THE HEART, LOCATED IN THE RIGHT ATRIM AT THE JUNCTION OF THE SUPERIOR VENA CAVA |
| LIFESTYLE FACTOR FOR CARDIAC DISEASE INDIVIDUAL CAN CHANGE | SMOKING, OBESITY AND OVERWEIGHT HIGH BLOOD CHOLESTEROL, HYPERTENSION, SEDENTARY LIFESTYLE, DIABETES MELLITUS |
| LIFESTYLE CAN NOT CHANGE | HEREDITARY, RACE, GENDER (MEN ARE AT GREATER RISK), INCREASING AGE |
| BETA BLOCKERS | TO SLOW THE HEART RATE AND LOWER BLOOD PRESSURE LIKE PROPANOLOL, ATENOLOL, TENORMIN, LOPRESSOR, INDERAL |
| BETA BLOCKERS ENDS IN (LOL) | PROPANOLOL, ATENOLOL |
| CARDIAC CYCLE | ATRIAL CONTRACTION, VENTRICULAR CONTRACTION, RECOVERY, HEART REST |
| CAD | CORONARY ARTERY DISEASE |
| CHF | CONGESTIVE HEART FAILURE |
| AORTA | THE LARGEST ARTERY VESSEL |
| THE LARGEST VEIN IN THE BODY | THE INFERIOR AND SUPERIOR VENAE CAVAE |
| BLOOD PRESSURE HIGHER THAN 119 SYS, 79 DYS | PRIMARY HYPERTENSION |
| <120 S, <80 D | BP NORMAL |
