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.
Shakespeare's only son, Hamnet, died in 1596 at the age of 11. His older daughter Susanna later married a well-to-do Stratford doctor, John Hall. Their daughter Elizabeth, Shakespeare's first grandchild, was born in 1608. In 1616, just months before his death, Shakespeare's daughter Judith married Thomas Quiney, a Stratford vintner.
