Live birth
Live birth
Live birth (/laɪv bɜːrθ/) refers to the process in which a fetus is expelled from the uterus of its mother and begins to breathe independently. The term is primarily used in zoology and obstetrics to differentiate between this and other types of birth, such as oviparity and ovoviviparity.
Etymology
The term "live birth" originates from the Old English words "lif" and "byrd", which mean "life" and "birth" respectively. It was first used in the medical context in the late 19th century.
