Study Notes

Medical Terminology Study Notes

Angiogram: X-ray test for visualizing blood flow in arteries or veins; 'angi' means vessel and 'gram' refers to a recording.
Angioplasty: Procedure where a tube or balloon opens up an artery; combines 'angi' for vessel and 'plasty' meaning plastic surgery.
Anoxia: State of being without oxygen; derived from 'a' indicating absence and 'ox' representing oxygen.
Aorta: The largest artery in the human body, crucial for blood circulation.
Aortic Stenosis: Condition characterized by the narrowing of the aortic valve; 'aortic' relates to the aorta and 'stenosis' means narrowing.
Apex of the Heart: Refers to the lower tip of the heart, significant in cardiac anatomy.
Arrhythmia: Irregular heartbeat; 'arrhythmic' indicates the absence of a normal rhythm.
Arterial Anastomosis: Surgical procedure creating a connection between two arteries; 'anastomoien' means providing a communication opening.
Arteriography: An X-ray diagnostic procedure specifically for imaging arteries.
Arteriole: A small type of artery, important in the vascular system.
Arteriosclerosis: A condition involving thickening and hardening of arterial walls; linked to loss of elasticity.
Artery: The primary blood vessels that transport blood away from the heart.
Atherectomy: Surgical removal of plaque from a blood vessel; 'ather' pertains to fatty substances and 'ectomy' means to cut out.
Atheroma: Fatty lumps that form within arteries' inner lining; 'oma' indicates a tumor-like growth.
Atherosclerosis: Hardening and narrowing of arteries due to plaque buildup, impacting blood flow.
Atrial: Pertaining to the atria, the upper chambers of the heart.
Atrioventricular Node: Component of the heart's electrical control system coordinating its upper section.
Atrium; Atria: The two upper chambers of the heart that receive blood.
Brachial Artery: Artery branching from the aorta supplying blood to the arm.
Bradycardia: Condition indicating a slow heartbeat, typically fewer than 60 beats per minute.
Bundle of His: Atrioventricular bundle of fibers located within the heart's septum, vital for electrical conduction.
Capillary: The smallest type of blood vessel; facilitates material exchange between blood and tissue.
Carbon Dioxide (CO2): Waste gas produced by body cells, transported to the lungs for exhalation.
Cardiogenic Shock: A condition where the heart fails to pump adequate blood, leading to poor oxygen and nutrient delivery to tissues.
Cardiomegaly: Enlargement of the heart, often indicative of underlying conditions.
Cardiomyopathy: Disease impacting heart muscle function, categorized into various types.
Coronary Arteries: Blood vessels branching from the aorta, supplying oxygen-rich blood to the heart muscle.
Cyanosis: Bluish skin discoloration, indicating low oxygen levels in the blood.
Deoxygenated Blood: Blood that is poor in oxygen, returned to the heart from the body.
Diastole: Phase of heart relaxation, allowing chambers to fill with blood.
Electrocardiogram: Diagnostic test recording the heart’s electrical activity, denoted as 'ECG'.
Endocardium: The inner lining of the heart, important for cardiac function.
Endothelium: The innermost layer of blood vessel walls, crucial for vascular health.
Hypercholesterolemia: Condition involving elevated cholesterol levels in the blood.
Hypoxia: Decreased oxygen availability in inhaled air, often experienced at high altitudes.
Interventricular Septum: Wall dividing the ventricles of the heart, critical for chamber function.
