Obstetrics (from the Latin obstare, "to stand by") is the medical specialty dealing with the care of all women's reproductive tracts and their children during pregnancy (prenatal period), childbirth and the postnatal period. Veterinary obstetrics is the same concept for veterinary medicine although theriogenology is more commonly used term that includes obstetrics, gynecology, and andrology. Almost all modern obstetricians are also gynecologists.

Prenatal care is important in screening for various complications of pregnancy. This includes routine office visits with physical exams and routine lab tests:

3D ultrasound of 3-inch (76 mm) fetus (about 14 weeks gestational age)

Fetus at 17 weeks

Fetus at 20 weeks

genetic screening for downs syndrome (trisomy 21) and trisomy 18 the national standard in the United States is rapidly evolving away from the AFP-Quad screen for downs syndrome- done typically in the second trimester at 16–18 weeks. The newer integrated screen (formerly called F.A.S.T.E.R for First And Second Trimester Early Results) can be done at 10 plus weeks to 13 plus weeks with an ultrasound of the fetal neck (thick skin is bad) and two chemicals (analytes) Papp-a and bhcg (pregnancy hormone level itself). It gives an accurate risk profile very early. There is a second blood screen at 15 to 20 weeks which refines the risk more accurately. The cost is higher than an "AFP-quad" screen due to the ultrasound and second blood test but it is quoted to have a 93% pick up rate as opposed to 88% for the standard AFP/QS. This is an evolving standard of care in the United States.

Sir Thomas More ( /ˈmɔr/; 7 February 1478 – 6 July 1535), known by Catholics as Saint Thomas More since 1935, was an English lawyer, social philosopher, author, statesman, and noted Renaissance humanist. He was an important councillor to Henry VIII of England and was Lord Chancellor from October 1529 to 16 May 1532. He is commemorated by the Church of England as a "Reformation martyr". He was an opponent of the Protestant Reformation and in particular of Martin Luther and William Tyndale.

More coined the word "utopia" – a name he gave to the ideal and imaginary island nation, the political system of which he described in Utopia published in 1516. He opposed the King's separation from the Catholic Church and refused to accept the King as Supreme Head of the Church of England, a title which had been given by parliament through the Act of Supremacy of 1534. He was imprisoned in 1534 for his refusal to take the oath required by the First Succession Act, because the act disparaged papal power and Henry’s marriage to Catherine of Aragon. In 1535, he was tried for treason, convicted on perjured testimony and beheaded.
