The pain of childbirth can not be compared to the joy of the cry of a newborn baby" this is a consolation message given to a mother who is going through the fear of giving birth. The process is said to be among one of the most painful processes that humans can go through. It is very painful and sometimes deadly, but the result from it brings joy and happiness to the mother, her family and the society at large. The process is characterized by a series of physical, emotional, psychological and hormonal changes in the body of the "baby carrier".
Nevertheless, it is one of the necessities of life, through which we all came to be. The over seven billion world population were all brought forth either by natural or artificial means. It is only the woman who stands tall to carry this cross for all of humanity. This is mainly due to the fact that they contain the necessary organs required for this unique process. Let us exploit the various mechanism of this amazing biological process
PARTURITION OR BIRTH
Is the process of bringing forth a child from the womb or uterus of a female reproductive system. This process can only occur in the female structure(body).
Parturition is climaxed by several weeks of pregnancy. During which the baby to be born matures from a clot of blood into and fully grown child within forty weeks or nine months. This period is divided into three sections each comprising of three months called the trimesters of pregnancy. The process begins after the fission of the male and female sex cells to form a structure known as ZYGOTE. The fission process is also known as fertilization, it occurs in the tube that connects the womb to the ovary where the female eggs are produced. This tube is called the fallopian tube, it serves as the meeting place for both the egg and the sperm after sexual intercourse.
After fertilization, the zygote moves to the womb or the uterus where it attaches itself to the mineral-rich layer of the uterine wall (implantation). At this stage, the zygote feeds the food lining in the uterus through diffusion via its membrane. After about a week a cord known as the umbilical cord is formed that connects the growing baby to another newly formed structure called the placenta which is connected to the mother. The zygote starts to differentiate where the specialization of cells begins. The cells divide rapidly and specialize forming the various organs of the body. Moving forward, the specialized cells begin to develop and enlarge. The cells continue to mature until about forty weeks where it is fully matured.
A complete baby is formed and the mother's body can't contain it anymore hence the need for it to expel. The period between fertilization and birth is called GESTATION PERIOD. The period varies from one mammal to the other. The one mentioned above is that of a human being.
STAGES OF CHILDBIRTH.
There are three stages of childbirth. Each stage is characterized by its own distinct physical and hormonal control. These stages occur in the last week of pregnancy
THE FIRST STAGE: DILATION
This is the first stage of labour. This prepares the various structures involved in the process. The vagina increase in size and the cervix which is the link between the vagina and the womb also open creating the birth canal. Signals of labour are given by the discharge of mucus or blood which block the cervix during pregnancy through the vagina. It is characterized by slight contractions of the walls of the uterus and the abdomen. This break the amniotic fluid leading to the lubrication of the virginal passage. This may take some hours or days for first-time mothers. As time goes on the cervix of the vagina opens wider up to about between six and ten centimetres.
SECOND STAGE: EXPULSION
This is the real process that the child comes out of. It is the most important and perhaps the most painful of all the three stages. It usually lasts for a few minutes and expels the baby from the mom's womb to the external environment. It is most painful in first-time mothers. Sometimes the tissues of the vagina over stretches leading to mechanical tearing of the vagina tissues. There are a series of powerful contractions and relaxations of the vaginal and abdominal walls. The resultant of these two forces of contraction gradually pushes the baby out of the womb through the birth canal. The baby is well-positioned such that the hard is pointing to the cervix. Also, the baby assumes a streamlined shape allowing for easy passage through the cancel. Few instances were recorded during birth where the child starts coming with other places other than the head. Special massaging mechanisms are employed to turn the baby in the right position.
THIRD STAGE: PLACENTAL STAGE
This is the final stage of childbirth it proceeds the coming of the child. It involves the removal of the placenta, umbilical cord and other things that accompanies it. It forms the climax of the whole process, the walls contract again to force the placenta and the umbilical cord and its associates from the womb of the mother. These things are collectively called after birth.
Sometimes, childbirth does not follow the known process, when this happens several measures are put in place to make sure the process comes naturally. But if all attempts fall, the surgical operation is one of the assured ways to ensure survival. The surgical operation ensures that at least one of the mother or the child survives. The process cut open the lower abdomen and get into contact with the child in the womb to ensure that both the mother and the unborn child is safe. This is done when all attempts of childbirth through the natural process fails. This is very critical and is often the last option due to its narrow surviving chance.
All mammals give birth to their younger ones for continuity and succession. childbirth is a very painful process the help bring smiles to the face of society. it consists of three stages the first stage which is the dilation stage, signals the mother and prepares the way for the unborn child to pass the second one is the expulsion stage where the abdominal and vaginal wall contracts and relax powerfully to push the child out through the birth canal into the external environment. the last stage is the placental stage. this is when the afterbirth comes out of the womb to climax the entire process.
