Pulmonary Circuit
Carries oxygen-poor blood to lungs.
Systemic Circuit
Delivers oxygenated blood to body tissues.
Pericardium
Double-walled sac enclosing the heart.
Pericardial Cavity
Fluid-filled space reducing heart friction. Between two layers of serous pericardium
Epicardium
Outer lining of the heart. Viseral layer and serous pericardium
Myocardium
Cardiac muscle layer of the heart; muscle cells
Endocardium
Inner lining of heart. (Valves, continuous w blood vessel lining)
Pericarditis
Inflammation of the pericardium. (Painful, pericardial friction rub)
Myocarditis
Inflammation of the myocardium. Weakens heart muscle
Endocarditis
Inflammation of the endocardium.(confined to heart valves- valve impairment)
Interatrial Septum
Separates right and left atria.
Interventricular Septum
Separates right and left ventricles.
, Fossa Ovalis
Remnant of fetal heart in atrium.
Superior Vena Cava and inferior vena cava
Two large veins that empty blood into right atrium.
Right and left pulmonary veins
Four veins that receive blood from lungs and empty it into left atrium
Right and left ventricles
Thick walled pumping chambers of the heart w trabeculae carneae
Pulmonary Trunk
Carries blood from right ventricle to lungs.
Left ventricle
pumps blood to the whole body via aorta
Aorta
Distributes oxygenated blood to the body.
Tricuspid Valve
Right AV valve with three cusps.
Mitral Valve
Left AV valve with two cusps.
Pulmonary Valve
Right semilunar valve with three cusps. No carne
Aortic Valve
Left semilunar valve with three cusps. No carne
Pulmonary Valve
Valve between right ventricle and pulmonary trunk.
Tricuspid Valve
Valve between right atrium and right ventricle.
Chordae Tendineae
Tendons connecting valves to papillary muscles. (Anchors cusps)
Papillary Muscles
Muscles that anchor chordae tendineae.
Incompetent Valve
