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 artery transports blood from the heart to the lungs. While most major arteries branch off from the aorta, the main pulmonary artery extends from the right ventricle of the heart and branches into left and right pulmonary arteries. The left and right pulmonary arteries extend to the left lung and right lungs. The pulmonary arteries are unique in that unlike most arteries which carry oxygenated blood to other parts of the body, the pulmonary arteries carry de-oxygenated blood to the lungs. After picking up oxygen, the oxygen rich blood is returned to the heart via the pulmonary veins. 1 of 1.
