paragraph_text: The aortic and pulmonary valves are located at the base of the aorta and the pulmonary trunk respectively. These are also called the ``semilunar valves ''. These two arteries receive blood from the ventricles and their semilunar valves permit blood to be forced into the arteries, and prevent backflow from the arteries into the ventricles. These valves do not have chordae tendineae, and are more similar to the valves in veins than they are to the atrioventricular valves. The closure of the semilunar valves causes the second heart sound.

paragraph_text: While pulmonary hypertension is unusual before 20 years of age, it is seen in 50% of individuals above the age of 40.  Progression to Eisenmenger's syndrome occurs in 5 to 10% of individuals late in the disease process.

paragraph_text: ABC and its variations are initialism mnemonics for essential steps used by both medical professionals and lay persons (such as first aiders) when dealing with a patient. In its original form it stands for Airway, Breathing, and Circulation. The protocol was originally developed as a memory aid for rescuers performing cardiopulmonary resuscitation, and the most widely known use of the initialism is in the care of the unconscious or unresponsive patient, although it is also used as a reminder of the priorities for assessment and treatment of patients in many acute medical and trauma situations, from first - aid to hospital medical treatment. Airway, breathing, and circulation are all vital for life, and each is required, in that order, for the next to be effective. Since its development, the mnemonic has been extended and modified to fit the different areas in which it is used, with different versions changing the meaning of letters (such as from the original 'Circulation' to 'Compressions') or adding other letters (such as an optional ``D ''step for Disability or Defibrillation).

paragraph_text: Theologus Autodidactus, written by the Arabian polymath Ibn al-Nafis (1213–1288), is the first example of a science fiction novel. It deals with various science fiction elements such as spontaneous generation, futurology, the end of the world and doomsday, resurrection, and the afterlife. Rather than giving supernatural or mythological explanations for these events, Ibn al-Nafis attempted to explain these plot elements using the scientific knowledge of biology, astronomy, cosmology and geology known in his time. Ibn al-Nafis' fiction explained Islamic religious teachings via science and Islamic philosophy.

paragraph_text: The United States two - dollar bill ($2) is a current denomination of U.S. currency. The third U.S. President (1801 -- 09), Thomas Jefferson, is featured on the obverse of the note. The reverse features an engraving of the painting The Declaration of Independence by John Trumbull. Throughout the $2 bill's pre-1929 life as a large - sized note, it was issued as a United States Note, National Bank Note, silver certificate, Treasury or ``Coin ''Note and Federal Reserve Bank Note. When U.S. currency was changed to its current size, the $2 bill was issued only as a United States Note. Production went on until 1966, when the series was discontinued. Ten years passed before the $2 bill was reissued as a Federal Reserve Note with a new reverse design. Two - dollar bills are seldom seen in circulation as a result of banking policies with businesses which has resulted in low production numbers due to lack of demand. This comparative scarcity in circulation, coupled with a lack of public knowledge that the bill is still in production and circulation, has also inspired urban legends and occasionally has created problems for people trying to use the bill to make purchases.

paragraph_text: The Times used contributions from significant figures in the fields of politics, science, literature, and the arts to build its reputation. For much of its early life, the profits of The Times were very large and the competition minimal, so it could pay far better than its rivals for information or writers. Beginning in 1814, the paper was printed on the new steam-driven cylinder press developed by Friedrich Koenig. In 1815, The Times had a circulation of 5,000.

paragraph_text: Some of the blood entering the right atrium does not pass directly to the left atrium through the foramen ovale, but enters the right ventricle and is pumped into the pulmonary artery. In the fetus, there is a special connection between the pulmonary artery and the aorta, called the ductus arteriosus, which directs most of this blood away from the lungs (which are not being used for respiration at this point as the fetus is suspended in amniotic fluid).

paragraph_text: Humans have two lungs, a right lung and a left lung. They are situated within the thoracic cavity of the chest. The right lung is bigger than the left, which shares space in the chest with the heart. The lungs together weigh approximately 1.3 kilograms (2.9 lb), and the right is heavier. The lungs are part of the lower respiratory tract that begins at the trachea and branches into the bronchi and bronchioles, and which receive air breathed in via the conducting zone. The conducting zone ends at the terminal bronchioles. These divide into the respiratory bronchioles of the respiratory zone which divide into alveolar ducts that give rise to the microscopic alveoli, where gas exchange takes place. Together, the lungs contain approximately 2,400 kilometres (1,500 mi) of airways and 300 to 500 million alveoli. Each lung is enclosed within a pleural sac which allows the inner and outer walls to slide over each other whilst breathing takes place, without much friction. This sac also divides each lung into sections called lobes. The right lung has three lobes and the left has two. The lobes are further divided into bronchopulmonary segments and lobules. The lungs have a unique blood supply, receiving deoxygenated blood from the heart in the pulmonary circulation for the purposes of receiving oxygen and releasing carbon dioxide, and a separate supply of oxygenated blood to the tissue of the lungs, in the bronchial circulation.

paragraph_text: When the Buffalo nickel had been in circulation for the minimum 25 years, it was replaced with little discussion or protest. The problems of die life and weak striking had never been solved, and Mint officials advocated its replacement. In January 1938, the Mint announced an open competition for a new nickel design, to feature early President Thomas Jefferson on the obverse, and Jefferson's home, Monticello on the reverse. In April, Felix Schlag was announced as the winner. The last Buffalo nickels were struck in April 1938, at the Denver Mint, the only mint to strike them that year. On October 3, 1938, production of the Jefferson nickel began, and they were released into circulation on November 15.

paragraph_text: Muslim physicians contributed to the field of medicine, including the subjects of anatomy and physiology: such as in the 15th century Persian work by Mansur ibn Muhammad ibn al-Faqih Ilyas entitled Tashrih al-badan (Anatomy of the body) which contained comprehensive diagrams of the body's structural, nervous and circulatory systems; or in the work of the Egyptian physician Ibn al-Nafis, who proposed the theory of pulmonary circulation. Avicenna's The Canon of Medicine remained an authoritative medical textbook in Europe until the 18th century. Abu al-Qasim al-Zahrawi (also known as Abulcasis) contributed to the discipline of medical surgery with his Kitab al-Tasrif ("Book of Concessions"), a medical encyclopedia which was later translated to Latin and used in European and Muslim medical schools for centuries. Other medical advancements came in the fields of pharmacology and pharmacy.
