Parturition is precipitated by several factors, including hormonal changes, mechanical stretching of the uterus, fetal signals, and maternal physiological changes. Hormones such as oxytocin and prostaglandins increase, promoting uterine contractions. The stretching of the uterine walls from the growing fetus stimulates further contractions. Additionally, the fetus releases signals that promote labor as it approaches maturity, while maternal factors like increased estrogen levels also play a crucial role in preparing the body for delivery.
Parturition is the term meaning delivery of a developed fetus. A related term, oviposition, means delivery of an egg containing an embryo.
They develop in the uterine horn, as the fetus grows, it will move into the uterus and then through the birthing canal at parturition.
Reproduction, females are bred by males, carry the fetus until parturition (birth).
This is where the egg is produced and the site in which the fetus grows until the parturition date where it will travel down into the birth canal.
hormone that stimulates milk production and the secretion of progesterone in mammals; hormone which stimulates secretion from the crop gland in birds. prolactin gonadotropic hormone secreted by the anterior pituitary; in females it stimulates growth of the mammary glands and lactation after parturition [syn: lactogenic hormone, luteotropin].
Parturition means to give birth.
