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.
My friends and family say I am obsessive about the subject. Shakespeare had three children. Susannah was born in May 1583, six months after William married Anne (so Anne was pregnant at the time of the wedding). Two years later (1585) the twins Judith and Hamnet (girl and boy) arrived.
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.
