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.
Birth and childhood. William Shakespeare was probably born on about April 23, 1564, the date that is traditionally given for his birth. He was John and Mary Shakespeare's oldest surviving child; their first two children, both girls, did not live beyond infancy. Growing up as the big brother of the family, William had three younger brothers, Gilbert, Richard, and Edmund, and two younger sisters: Anne, who died at seven, and Joan.
