Medical Terminology:A Programmed Approach Paula Bostwick and Heidi Weber Chapter 12: The Cardiovascular System
Learning Outcomes • Identify and discuss the structure and function of the cardiovascular system. • Define combining forms used in building words that relate to the cardiovascular system. • Summarize common diagnoses, laboratory tests, and clinical procedures used in testing and treating disorders of the cardiovascular system. • Define the major pathological terms of the cardiovascular system. • Define surgical terms related to the cardiovascular system. • Recognize common pharmacological classifications used to treat disorders of the cardiovascular system. Define major pathological conditions of the cardiovascular system
Function/Structure • Delivers blood to the body • Oxygen and Nutrients to the body • Removes waste and Carbon Dioxide
Combining Forms • angi(o) blood vessel • aort(o) aorta • arteri(o), arter(o) artery • ather(o) fatty matter • atri(o) atrium
Combining Forms • cardi(o) heart • hemangi(o) blood vessel • pericardi(o) pericardium • phleb(o) vein
Combining Forms • sphygm(o) pulse • thromb(o) blood clot • vas(o) blood vessel • ven(o) vein
Heart Valves • Four Chambers • Four valves allow blood flow in one directions • Pulmonary, Aortic,Tricuspid, and Mitral Valves
bicuspid valve mitral valve semilunar valve pulmonary valve aortic valve Structure & Function • valves • arteries • veins • lumen • atrioventricular valve • tricuspid valve
Vessels • Carry blood within the heart • To tissues and organs • Expand and Constrict to regulate blood flow
Blood Pressure • Pressure in arteries • Sphygmomanometer • Stethoscope • Contraction and Relaxation pressures
Fetal Circulation • Fetal circulation is the circulatory system of the unborn child. • Includes the umbilical cord and the blood vessels within the placenta
Diagnostic, Procedural, Labs • Diagnostic, procedure and laboratory findings assist the physician in diagnosing medical conditions. • Final diagnosis • Assist in treatment planning
Pathological Conditions • Heart Rhythm • Sinus rhythm normal • Abnormal rhythms can be life threatening • risk factor • arrhythmia • bradycardia • tachycardia • atrial fibrillation • fibrillation • dysrhythmia • flutter • bruit • murmur
Pathological Conditions (cont.) • rub gallop palpitations • atrioventricular block • heart block • premature atrial contractions (PACs) • premature ventricular contractions (PVCs)
Blood Pressure • Elevated blood pressure can lead to cardiovascular disorders • Low blood pressure is usually not treated. • hypertensive heart disease • hypertension = high blood pressure • hypotension = low blood pressure • essential hypertension • secondary hypertension
Diseases of the Blood Vessels • Blood vessels carry blood throughout the body • Damaged blood vessels compromise flow • Decreasing oxygen to the tissues and organs.
Artery, Heart, Lung Disease • Heart and lungs work together to provide oxygen • Inadequate heart function • Cause lung disease.
Valve Conditions • Valves responsible for maintaining blood flow • Diseased valves cause cardiovascular symptoms
Surgical Terms • Cardiovascular surgery • Blockages within the cardiac vessels • Disorders of the heart valves
Pharmacological Terms • Medications can treat CV diseases and symptoms • Drug Therapy • Angina, heart attack, hypertension, high cholesterol, congestive heart failure, rhythm disorders and vascular problems
Chapter Review • Identify and discuss the structure and function of the cardiovascular system. • Define combining forms used in building words that relate to the cardiovascular system. • Summarize common diagnoses, laboratory tests, and clinical procedures used in testing and treating disorders of the cardiovascular system. • Define the major pathological terms of the cardiovascular system. • Define surgical terms related to the cardiovascular system. • Recognize common pharmacological classifications used to treat disorders of the cardiovascular system. Define major pathological conditions of the cardiovascular system
