Final answer:
Spontaneous delivery is the natural process of giving birth without medical intervention, driven by a positive feedback system that is essential for the well-being of the mother and baby. In some cases, a Caesarian section may be utilized as an alternative delivery method for safety.
Step-by-step explanation:
Spontaneous delivery refers to the natural process of childbirth where the body expels the baby without medical intervention. During a spontaneous delivery at full term, the body undergoes significant changes, with labor and delivery being driven by a positive feedback system. This system ensures that once labor begins, the events of childbirth progress rapidly, which is essential for the safety of both the mother and the baby. Labor is marked by the rupture of the amniotic sac, commonly known as the 'water breaking', and is followed by strong uterine contractions. If there are complications or health concerns, an alternative delivery method, such as a Caesarian section, may be performed to ensure a safe birthing process.
