Cardiology |
The study of the heart |
|
|
Precordium |
The area of the anterior chest wall overlying the heart and great vessels. |
|
|
3 layers of tissue in the heart? |
Endocardium, myocardium, and epicardium |
|
|
Endocardium |
Innermost layer that lines the valves. Has a smooth and shiny surface. |
|
|
Myocardiun |
The middle layer of the heart. The thickest layer. Composed of cardiac muscle. |
|
|
Epicardium |
Thin outermost layer. Helps form the pericardium. |
|
|
Pericardium |
Sling like structure that supports the heart. Attaches the heart to diaphragm and blood vessels. Has three layers |
|
|
Pericardium |
Sling like structure that supports the heart. Attaches the heart to diaphragm and blood vessels. Has three layers |
|
|
Three layers of pericardium? |
Epicardium(visceral pericardium-innermost), parietal pericardium, fibrous pericardium |
|
|
Pulmonary Circulation |
The path of blood flow from the right side back to the left |
|
|
Pulmonary Circulation |
The path of blood flow from the right side back to the left |
|
|
Systemic Circulation |
The path of blood flow from the left to all of the organs and back to the right |
|
|
Atrium |
Upper chambers that receive blood into the heart |
|
|
Atrium |
Upper chambers that receive blood into the heart |
|
|
Centricles |
The lower chambers that pump blood out of the heart |
|
|
Great vessels |
The superior and inferior vena cava, pulmonary artery, pulmonary veins, and the aorta |
|
|
Great vessels |
The superior and inferior vena cava, pulmonary artery, pulmonary veins, and the aorta |
|
|
Atrioventricular Valves |
Between the atria and ventricles. Blood flows through them into the ventricles |
|
|
Great vessels |
The superior and inferior vena cava, pulmonary artery, pulmonary veins, and the aorta |
|
|
Atrioventricular Valves |
Between the atria and ventricles. Blood flows through them into the ventricles |
|
|
Semilunar valves |
Control the outflow of blood. Exit valves |
|
|
Chordae Tendineae |
Tough fibrous bands of tissue that attach the cusps and ventricular wall |
|
|
Stenosis |
Narrowing of the valves |
|
|
Murmur |
Abnormal heart sounds |
|
|
Coronary artwries |
Supply the myocardium with blood and oxygen. |
|
|
Ischemia |
When coronary blood flow diminishes and the myocardium experiences oxygen deprivation |
|
|
What does the cardiac conduction system contain? |
The sinoatrial node, the atrial conducting fibers, the atrioventricular node, and the His-Purkinje sytem |
|
|
Sinoatrial Node( SA) |
Creates a electrical signal for the heart called the cardiac impulse.(60-100 times per min) Called the "pacemaker" of the heart. |
|
|
Atrioventricular Node( AV) |
1) acts as a path for the cardiac impulse to travel from the atrial conducting fibers to the His. 2)slows the cardiac impulse as it moves through the AV to the His. |
|
|
Bundle of His and it's two branches? |
Specialized conduction tissue located in the interventricular septum. Divided into left and right bundle branches which send out long fibers called purkinje fibers. |
|
|
Purkinje Fibers |
Conduct the cardiac impulse through the ventricles, ensuring a coordinated contraction of both ventricles. |
|
|
Two important qualities of the heart? |
Automaticity( automatic) and rhythmicity( has a rythm) |
|
|
Electrocardiogram (ECG) |
Record of electrical signals of the heart |
