Cardiovascular
Abbreviations and Common Terms
| Term | Definition |
|---|---|
| CARDIO | HEART |
| VASCULAR | BLOOD VESSELS |
| 4 CHAMBERS of: | 2 ATRIA "RECEIVING ROOMS" 2 VENTRICLES "SENDING ROOMS" |
| HEART IS SEPARATED INTO R/L - RIGHT | RIGHT SIDE RECEIVES BLOOD FROM BODY; DELIVERS TO THE LUNGS |
| HEART IS SEPARATED INTO R/L - LEFT | LEFT SIDE RECEIVESS BLOOD FROM LUNGS; DELIVERS OXYGEN-RICH BLOOD TO BODY |
| VALVES BETWEEN EACH ATRIUM/VENTRICLE: 2 VALVES - R/L - RIGHT | RIGHT ATRIOVENTRICULAR VALVE |
| VALVES BETWEEN EACH ATRIUM/VENTRICLE: 2 VALVES R/L - LEFT | LEFT ATRIOVENTRICULAR VALVE (MITRAL VALVE) |
| VALVES PLACED BETWEEN EACH VENTRICLE/LARGE ARTERY: | PULMONARY & AORTIC |
| WHICH SIDE IS OXYGEN - RICH BLOOD | LEFT |
| WHICH SIDE IS OXYGEN - POOR BLOOD | RIGHT |
| VALVUL/O | VALVE; PREVENTS BACKFLOW OF BLOOD |
| MITRAL VALVE | CONNECTS THE LEFT ATRIUM & VENTRICLE |
| AORTIC VALVE | CONNECTS THE LEFT VENTRICLE TO THE OUTGOING BLOOD VESSEL; THE AORTA |
| TRICUSPID VALVE | CONNECTOR BETWEEN ATRIUM AND VENTRICLE |
| PULMONARY VALVE | CONNECTS RIGHT VENTRICLE AND OUGOING BLOOD VESSEL; THE PULMONARY ARTERY |
| RIGHT VENTRICLE | SENDS BLOOD TO LUNGS FOR FRESH O2 AND TO DISCARD EXCESS CO2 |
| LEFT VENTRICLE | FRESH BLOOD IS SENT OUT FROM HEART VIA LEFT VENTRICLE TO THE REST OF THE BODY; PROVIDES O2 & COLLECTS THE BODY'S CO2 WASTE. |
| ATRI/O | ATRIUM - UPPER CHAMBER OR PORTION OF EACH SIDE OF HEART |
| SEPT/O | SEPTUM - (Plural: Septa) "Partition" OR "Dividing Structure" |
| VENTRICUL/O | VENTRICLE - LOWER CHAMBER OR PORTION OF EACH SIDE OF HEART. (Venter "Stomach" + Icle "Little" = Little Stomach |
| CARDI/O | HEART Ex. Cardiovascular, Cardiology I&O are dropped when combining: Ex. Myocarditis |
| CORON/O | HEART Ex. Coronary Artery |
| CIRCULATION LOOP BEGINS | LEFT VENTRICLE FORCES BLOOD INTO AORTA (Main Outgoing Vessel)--> AORTA BRANCHES INTO ARTERIES--> BLOOD FLOWS INTO CAPILLARIES (Tiny Vessels)-->O2 PASSES INTO TISSUES AND GIVES BACK THEIR WASTE |
| CIRCULATION LOOP RETURN | AFTER WASTE IS PICKED UP, JOURNEY BEGINS BACK TO HEART VIA VEINS --> SMALLER VEINS COLLECT INTO LARGER VEINS AND COLLECT INTO THE (Upper) SUPERIOR VENA CAVA & (Lower) INFERIOR VENA CAVA AND RETURN BLOOD TO THE RIGHT ATRIUM |
| CIRCULATION LOOP RETURN | AT THE SAME TIME THE LEFT VENTRICLE PUMPS BLOOD INTO THE AORTA, THE RIGHT VENTRICLE PUMPS BLOOD INTO THE PULMONARY ARTERY |
| PULMONARY ARTERY | CARRIES BLOOD TO THE LUNGS TO ATTAIN O2 AND DISCARD CO2 --> AFTER GAS EXCHANGE(S) |
| PULMONARY VEIN | --> BLOOD RETURNS VIA THE MAIN PULMONARY VEIN --> PULMONARY VEIN DUMPS O2 RICH BLOOD INTO THE LEFT ATRIUM. WHEN VALVE OPENS BETWEEN LEFT ATRIUM AND LEFT VENTRICLE, BLOOD FILLS THE VENTRICLE AND CYCLE REPEATS |
| AORT/O | AORTA - MAIN ARTERY LEAVING HEART; DISTRIBUTES OXYGENATED BLOOD THROUGH BODY |
| ARTERI/O | ARTERIES ARE THE LARGE BLOOD VESSELS THAT CARRY OXYGENATED BLOOD FROM HEART TO BODY'S TISSUES. (Artery: "Trachea or Windpipe") Ex. Arteriosclerosis |
| ATHER/O | FATTY PLAQUE "Gruel or Poridge" Ex. Atherosclerosis |
| ARTERIOSCLEROSIS | HARDENING OF AN ARTERY |
| ATHEROSCLEROSIS | HARDENING OF ARTERY DUE TO FATTY PLAQUE BUILD UP |
| PHLEB/O, VEN/O | (Phlebo "vein" + tomy "inscision") = PHLEBOTOMY; THE DRAWING OF BLOOD |
| ANGI/O, VAS/O, VASCUL/O | VESSEL; "jar" or "pitcher" |
