The Stages Of The Birthing Process

1. These enzymes are used by the sperm to create an opening in the corona radiata, zona pellucida, and plasma membrane of the oocyte for the sperm to pass through

At one month of pregnancy the baby is still any embryo and it is made up of two layers which will soon produce into body parts and organs. In the first two weeks of pregnancy a women isn’t actually pregnant because the women’s body is preparing for ovulation as usual. You usually ovulate (release an egg) around two weeks after the first day of your period this depends on the length of your period. Then during the third week after the first day of your last period your fertilised egg moves across the fallopian tube towards the womb. The egg starts off as a single cell but it divides multiple times. By the time the egg reaches the womb it becomes the mass of 100 cells which is known as an embryo. In the fourth week of pregnancy the embryo grows and develops in the lining of the womb. The outer cells reach out and link themselves with the mothers blood supply. The inner cells form

into an early stage embryo while still in a test tube. Scientists place the early stage embryo into

The baby begins to breathe through its nose and use its lungs. The hole in the heart begins to close. The digestive system boots up with the baby beginning to feed.

During the second trimester, a method is used called Dilation and Evacuation (D&E). During D&E, a forceps is used to take out larger pieces of the child, while a curette scrapes the smaller tissues out. Following this, a vacuum extracts any remaining pieces of the child. During the third trimester, a (now outlawed in most states) procedure is performed called “Partial Birth Abortion” During partial birth abortion, the child is partially delivered, and the skull is subsequently crushed or drilled into, thus killing the child.

A blastocyst is a ball of sixteen somatic cells that contains a thin spherical wall of cells surrounding a fluid-filled center which resembles a fluid-filled balloon. There are no organs or tissues at this stage and lacks a body plan. Eventually 9 six days after conception, the blastocyst attaches to the mom so it can join

Biological development of a fetus is vary rapid and complex over the nine-month period in the womb. When both the male spermatozoon and the female ovum combine it forms what is called a zygote which holds the twenty-three pairs of chromosomes. The zygote or the embryo undergoes cell division and makes its way to the uterine wall to implant itself, this process is completed about ten days after conception. By the end of the eighth week the organ systems have formed and human characteristics can start to be noticed. From the eighth week until birth the embryo is now labeled a fetus. Quickening can occur from the sixteenth week until birth, this is where the mother can feel the fetus moving. Around the twenty-second week viability can take place, this is where the fetus can survive outside the womb. The nine-month period of being pregnant is split into different trimesters. With the different trimesters there are different abortion procedures can be used to remove the fetus.

When an embryo becomes a fetus at eight weeks, it is approximately 3 centimeters; by the time the fetus is considered full-term, he or she may be 50 centimeters (Brisbane 60). The fetal stage, that takes place during week 9 to birth, result in a whole bunch of changes. (Brisbane 61). During the fetal stage, all parts of the body mature, and the overall of the baby size increases. Although all of the organ systems were formed during embryonic development, they continue to develop and grow during the fetal stage as well. During the third month, the reproductive system becomes developed and the sex of the baby becomes apparent (Staff). For girls, the ovarian follicles begin to form and for boys the prostate gland. Throughout months four through six, the heartbeat grows stronger and other body systems become further developed (Brisbane 63). Features such as fingernails, hair, eyelashes and toenails form. During the period from seven months until birth, the fetus continues to develop, put on weight, and prepare for life outside the womb (Brisbane 64). The lungs begin to expand and contract, preparing the muscles for breathing (Brisbane 64). The time in which the baby is born is a very critical. In some situations, a baby can be born as early as 7 months. When a baby is born too early, his ar her organs are not usually fully formed. This can result in many complications and health problems. Including, If premature pregnancy is the case, the baby would need some intensive care in hospitals. If the baby survives the stages, at the end of the nine month of pregnancy the baby will turn to a head-down position to prepare for birth. If the baby is not in the head-down position and in breech position a cesarean section may be required, which can cause many more complications. If a baby passes all these crucial factors, it is guaranteed to be born

The third stage of labor happens after you baby has come out, when your womb contracts and the placenta comes out through the vagina.

    According to parents.com, after conception, a fetus begins to develop rather quickly. In the fifth week of pregnancy, a baby’s heart begins to beat. A baby also develops three distinct layers, ectoderm, endoderm, and mesoderm. These three layers will eventually form the body systems that are necessary

Important stages of pregnancy: Pregnancy is counted from the first day of the mother 's last period. Important development immediately takes place after fertilisation of egg and sperm cells. It divides into many cells in the first week, which forms a zygote made out of 100 to 150 cells that are already differentiating. In the second week, the zygote is then changed to an embryo and it sticks to the uterine wall. This process takes up to nine months to form and develop a baby.

[1] "Development of the embryo begins at Stage 1 when a sperm fertilizes an oocyte and together they form a zygote."

Giving birth is something that happens many times daily all over the world. Though many people who have not experienced giving birth, such as men, may think all the woman has to do is push a couple times and it's over, that is not the case. There are three stages to giving birth according to BabyCentre including contractions, pushing, and delivering the placenta.

The fetal stage is the stage in which is marked by rapid growth and preparation

Birth of a child can be such a happy time, especially when the little one is very healthy. We all have seen the movies when a new child is born, some of us are lucky to see it first hand. Some of us do get goose bumps, me being one of them. It is just so exciting to see that little life come out of what has been in that big belly for nine months. We sometimes refer to the birth of a child as labor. If only it was as easy as the name sounds. However, it is not. There are three main stages in birth. The first stage is the longest stage that can last 12 to 14 hours with the first birth, and later births are shorter. Dilation and effacement of the cervix take place here. That is when the uterine contractions gradually become more frequent and
