What are the prenatal development phases?

There are three phases of prenatal development: concept phase, embryonic phase and fetal phase. Each phase of prenatal development is performed over about 40 weeks, which is the average length of most pregnancies. The concept stage is the shortest and the fetal phase is the longest. It is a good idea for a mother to realize exactly what is happening during each stage of development so that she can better understand what is happening with her child and her body.

The concept phase takes only about two weeks and during this time the sperm finds the way to the egg and implants inside. After the egg implantation, the egg tube passes through the uterus. The egg can take a week to get into the uterus and implants in. At this stage, the egg is referred to as a zygot and the cell division has already begun. The cell division continues until Zygota becomes a blastocyst, which is already Made up primitive basic components that make up the human body.

Once the blastocystIt goes to the wall of the uterus, becomes known as an embryo and begins with an embryonic stage of prenatal development. At this stage of development, the embryo begins to look like something that resembles a child when the cells are still divided. The embryonic stage usually lasts until the woman has been pregnant for 11 weeks. At the end of the embryonic stage, the embryo, legs and heart rhythm will have an embryo. It is at this stage of prenatal development that most women are for their first ultrasound, which helps doctors to determine that the child usually evolves.

At the end of 11 weeks, embryo becomes known as the fetus and begins a fetal stage. Most women combine the fetal phase with the beginning of the second trimester, which occurs at the end of the third month of pregnancy. During this, the child's sex, and other main organs of the body begin to form and the fetus can have hair, teeth and even small nails and nails before the end of this phase. This is the pregnancy phase when most women feel their children kicking for the first time, and sex can usually be determined by ultrasound for about 20 weeks. At the end of the fetal phase will be plFrom about 40 weeks fully developed and ready for delivery.
