The human birthing process
Table of Contents
The baby soon outgrows the energy requirements that the placenta previously met, and is time to be conceived into the open world by the mother.
The release of oxytocin, a hormone, instructs the mother’s body that the food supply for the baby can no longer be met, which bring about contractions in the mother and soften the tissue of the cervix where the baby will pass through.
The ‘waters then break’ caused by the pressure of the contractions, the amniotic fluid which once surrounded the fetus is released.
This is where the baby is pushed down the cervix through the vagina, out to the open world. This is the hardest stage of labor, and it involves the mother ‘pushing’ with the contractions to force the baby out. This is a natural behavioral response in the mother due to the pain involved in getting the baby out.
This is where the placenta is excreted after the newly born baby, as it is no longer required in the body and has served its function. The newly born baby must survive in the open world with its maternal parents there to help them learn, grow up healthily and care for.
