Document Summary

Electrical impulse that triggers contraction of heart muscle originates in the sinoatrial node. Pulmonary vein carries oxygenated blood from lungs to left atrium. Capillaries permit o2 and nutrients to exchange with co2 and waste materials. Tricuspid valve lies between right atrium and right ventricle. Pulse force of blood ejected form heart causing regular expansion and contraction of arterial walls. Right atrium tricuspid valve right ventricle pulmonary valve. Atrioventricular node area of specialized cardiac tissue that receives cardiac impulse from sinoatrial node. Atrial flutter cardiac dysrhythmia characterized by rapid, regular, contractions. Aneurysm widening of weakened portion of arterial wall. Myocardial infraction dead myocardial tissue resulting from interrupted blood flow. Mitral valve prolapse valve between left atrium and ventricle becomes enlarged and protrudes into left atrium during systole.
