Cardiovascular Anatomy Flashcards
Aorta
Artery carrying blood from the heart (left ventricle) to the rest of the body
Aortic valve
Heart valve between the left ventricle and ascending aorta
Atrial septum
Heart tissue that separates the right atrium from the right atrium
AV node
Atrioventricular node: receives the electrical activity from the SA node and conducts it to the ventricles; the right bundle and the left bundle
Left atrium
LA: chamber in the heart hat receives oxygenated blood from the pulmonary vein
Left ventricle
LV: chamber in the hear that receives oxygenated blood from the left atrium
Mitral valve
Hear valve between left atrium and left ventricle
Myocardium
Heart muscle
Pulmonary artery
Artery carrying blood from the heart (right ventricle) to the lungs
Pericardium
The lining surrounding the heart
Pulmonary artery
Artery carrying blood from the heart (right ventricle) to the lungs
Pulmonary vein
Vein carrying blood from the lungs to the heart (left atrium)
Pulmonic valve
Heart valve between the RV and pulmonary artery
Right atrium
RA: chamber in the hear that receives blood from the vena cava, sends it to the right ventricle
Right ventricle
RV: chamber in the hear that receives blood from the RA, sends it to the lungs
SA node
Sinoatrial node; pacemaker of the heart
Tricuspid valve
Heart valve between right atrium and right ventricle
Ventricular septum
Heart tissue that separates the right ventricle from the left ventricle
Aneurysm
Localized ballooning of a vessel due to a weakened vessel wall
Artery
Blood vessel carrying blood away from the heart,; muscular, contracts
Bruit
A whooshing sound heard during auscultation indicative of blockage or aneurysm
Dissection
Blood flow into the wall layers of an artery causing the arterial walls to split apart
Deep venous thrombosis
DVT, deep clot in the extremity
Embolism
Obstruction of blood vessel by a traveling clot of blood or foreign substance
Hemangioma
Tumor consisting of blood vessels
Stenosis
Narrowing of a body opening or passage
Thrombus
blood clot or blockage
Vein
Vessels carrying blood towards the heart; soft, compressible
