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 main pulmonary artery is responsible for transporting oxygen-depleted blood away from the heart and back toward the lungs. The main artery splits into the left pulmonary artery and the right pulmonary artery, each of which directs the blood to the corresponding lung. Along with the umbilical arteries, these are the sole arteries in the body that transport oxygen-depleted blood. The umbilical arteries are located in the uterus. The pulmonary artery, or pulmonary trunk, originates from the bottom of the right ventricle of the heart. The artery is wide and short, measuring 1.2 inches wide and 2 inches long. When blood pressure increases in the right or left pulmonary artery or the main pulmonary artery, this is referred to as pulmonary hypertension and can result in symptoms such as fainting, dizziness and shortness of breath.
