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 1585, Anne bore twins, baptized Hamnet and Judith Shakespeare. Hamnet died at the age of eleven, by which time William Shakespeare was already a successful playwright. Around 1589, Shakespeare wrote Henry VI, Part 1, which is considered to be his first play.
