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.
In 1582, at the age of eighteen, William Shakespeare married twenty-six-year-old Anne Hathaway. Their first daughter, Susanna, was not baptized until six months after her birth-a fact that has given rise to speculation over the circumstances surrounding the marriage.
