Medical Terminology Code (3401 ) Cardiovascular System Objectives Identify, pronounce, spell, and build words related to the cardiovascular system.  The cardiovascular (CV) system is composed of the heart and blood vessels.  The heart is located between the lungs, with its apex directed toward the left. The heart wall is divided into three layers: Epicardium Myocardium Endocardium  Epicardium is the outer protective layer of the heart wall Myocardium is the muscular thick middle layer wall of the heart. It is composed of cardiac muscle fibers, which enable heart contractions. Endocardium is the thin inner layer of the heart wall, this layer lines the inner heart chambers and covers heart valves Pericardium is the fibrous sac that surrounds the heart. The vascular system consists of: 1. Arteries, the vessels that carry blood away from the heart. Arterioles are small arteries that lead into the capillaries. 2. Capillaries, the smallest vessels, through which exchanges take place between the blood and the tissues. 3. Veins carry blood back to the heart. The small veins that receive blood from capillaries and drain into the veins are venules. Roots for the Heart Combining Meaning Word Analysis form Cardi/o Heart Cardi/o/megaly : enlargement of the heart. megaly: enlargement Atri/o Atrium Atri/o/megaly : enlargement of the atrium. megaly: enlargement Ventricul/o Ventricle Ventricul/ar : pertaining to a ventricle Valvul/o Valve Valvulitis : inflammation of a valve Sten/o Narrowing Valve stenosis :narrowing of valve opening Roots for the Blood Vessels Combining Meaning Word Analysis form Angi/o Vessel Angi/o/plasty : repair of a vessel Vas/o Vessel Vaso/constriction: narrowing of a blood vascul/o vessel Vascul/itis : inflammation of blood vessels Arteri/o Artery Arteri/o/scler/osis : hardening of the artery Arteriol/o Arteriole Arteriol/itis : inflammation of an arteriole Aort/o Aorta Aort/o/stenosis : narrowing of the aorta Ven/o, ven/i Vein Ven/o/stasis : stopping of flow of blood in a vein Phleb/o Vein Phlebostasis -stasis: stopping of flow Phleb/ectasis : expansion of a vein -ectasis: dilation, expansion Combining form Meaning Word Analysis Ather/o Fatty plaques Athero Sclero : hardening Osis: condition Thromb/o Blood clot Thrombolysis: destruction of blood vessels clots Embol/o Embolus Embolectomy : surgical removal of embolus Hemangi/o blood vessel Hemangioma : tumor of blood vessel Analysis of common medical terms Cardiovascular Cardio : heart Vasculo : blood vessels ar : pertaining to Pericardium Peri : around Cardi : heart um: singular noun ending Myocardium Myo : muscle Cardi: heart um: singular noun ending Endocardium Endo : within Cardi: heart um: singular noun ending Cardiologist Cardio: heart Logist : specialist Cardiology Cardi: heart Logy : science Hematologist hemato: blood Logist : specialist Cardiomyopathy Cardi : heart Myo : muscle Pathy : condition Thank You
