What is parturition?

Parturition is the process of giving birth to offspring, which can occur in various animals including mammals and birds. In mammals, it involves a complex series of physiological and hormonal changes that prepare the female for the delivery of her offspring.

The process of parturition typically involves three stages: The first stage, called the latent phase, is characterized by contractions of the uterus that gradually become stronger and more frequent. During this phase, the cervix begins to dilate and the fetal membranes rupture, releasing amniotic fluid.

The second stage, known as the active phase, is marked by stronger and more coordinated contractions of the uterus, which push the fetus through the birth canal. This stage can take several hours and may involve the use of various interventions, including forceps or vacuum extraction, to assist with delivery.

The third and final stage of parturition involves the delivery of the placenta, which provides nutrients and oxygen to the fetus throughout pregnancy. After the placenta is delivered, the uterus continues to contract to prevent excessive bleeding and help the uterus return to its pre-pregnancy state.

Overall, parturition is a complex and carefully orchestrated process that requires precise hormonal and physiological changes to ensure the safe delivery of offspring.
