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.
We know that Shakespeare was baptized on April 26, 1564 and it is assumed that he was born on April 23, 1564. We also know that in 1582 at age eighteen, Shakespeare married Anne Hathaway, an older women who was twenty six at the time. Shakespeare left Stratford for London to make his fortune roughly fours years later.
