This piece is from of Nabucco, an opera in four acts by Italian composer Giuseppe Verdi (1818-1901) to an Italian libretto by Temistocle Solera. It is also known by its Italian title Va, Pensiro, (Fly, My Thoughts).Nabucco was based on the Biblical story of the plight of the Jews as they are exiled from their homeland by the Babylonian King Nebuchadnezzar. The historical events are used as background for a romantic and political plot.he popular song  Rivers of Babylon  uses some of the words from the same Psalm. Verdi's first opera, Oberto, which was produced by Milan's La Scala in November 1839 achieved a degree of success, after which Bartolomeo Merelli, La Scala's impresario, offered the young composer a contract for two more works.
Veins can be classified as pulmonary veins and systemic veins. The pulmonary veins are a set of veins that deliver oxygenated blood from the lungs to the heart and the Systemic veins drain the tissues of the body and deliver deoxygenated blood to the heart.
The pulmonary vein is the only vein to carry oxygenated blood which is on its way to the heart from the lungs. The diagram also shows you that the right and side of the heart, both atrium and ventricle, contains only deoxygenated blood.his blood moves through the heart on its way to the lungs where it picks up oxygen and releases carbon dioxide. The left hand side of the heart contains only oxygenated blood which has come from the lungs and is destined to be distributed throughout the body.
