Surfactant is a complex substance containing phospholipids and a number of apoproteins. This essential fluid is produced by the Type II alveolar cells, and lines the alveoli and smallest bronchioles.
William and Anne Shakespeare had three children. Their first child was Susanna, born a mere six months after the wedding of her parents. She was christened on May 26, 1583, and twins arrived in January, 1585.
William Shakespeare was baptized April 26, 1564, and although it's impossible to know exactly what day he was born, it is widely agreed upon that he was born April 23 of that year. April 23 would be a very convenient day for Shakespeare's birth, as he died on the same day in 1616, and it is also St. George's Day. He grew up in Stratford-upon-Avon, a town 22 miles southeast of Birmingham, with seven siblings, three of which did not live to adulthood. William Shakespeare was the oldest surviving child of John and Mary Shakespeare.
