LEFT ATRIUM • general features: lies to the left of and slightly posterior to the right atrium; receives blood from the pulmonary blood circuit via the pulmonary veins; • right and left pulmonary veins: total of _________________ vessels; drain into the left atrium; return oxygenated blood to the heart from the _______________; • auricle of the left atrium: similar in structure to the auricle of the right atrium; only part of left atrium to contain pectinate muscles; LEFT VENTRICLE • general features: walls are thickest in this chamber; receives blood from the left atrium; drained by the aorta; trabeculae carneae are muscle bundles that line the ventricular walls; • left atrioventricular valve: also known as the ___________________ or __________________ valve; consists of 2 cusps; made up of dense connective tissue covered by endothelium; • papillary muscles of the left ventricle: are ____________ in number; internal projections of the myocardium; each attaches to a separate cusp of the bicuspid valve via the chordae tendineae; • aorta: drains the left ventricle; carries blood to most parts of the body within the systemic blood circuit; • aortic semilunar valve: similar in structure to the pulmonary semilunar valve, consisting of 3 cusps; made up of dense connective tissue covered by endothelium.
