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.
Pulmonary Circulation. The pulmonary circulation carries the blood to and from the lungs. In the heart, the blood flows from the right atrium into the right ventricle; the tricuspid valve prevents backflow from ventricles to atria.The right ventricle contracts to force blood into the lungs through the pulmonary arteries.n the lungs oxygen is picked up and carbon dioxide eliminated, and the oxygenated blood returns to the heart via the pulmonary veins, thus completing the circuit. In pulmonary circulation, the arteries carry oxygen-poor blood, and the veins bear oxygen-rich blood. Sections in this article: 1  Introduction.
