4 Weeks Pregnant

Pregnancy – What development in the baby and mother happens during Weeks 4?

As the implantation has taken place during week 3, in the fourth week of pregnancy the blastocyst will get divided into different layers of cells, these cells will now convert into the embryo and placenta.

The placenta and embryo will later transform themselves into a fetus. The baby will be called a fetus until he or she is born.

The embryo is made up of two kinds of layers; one of them is called hypoblast, while the other one is referred to as epiblast.

The function of both these two layers is totally different from each other.

Responsibilities of the hypoblast:

1 – Yolk sac formation to provide nutrients to the fetus.

2 – Formation of extraembryonic mesoderm which will provide the required support to the yolk sac, it is also responsible for proper blood supply to the fetus.

Responsibilities of the epiblast:

The epiblast is made up of three different layers, the ectoderm, the endoderm, and the mesoderm.

1 – The ectoderm is responsible for the development of the nervous system, the hairs, and the skin tissues of the fetus.

2 – The endoderm is responsible for the development of the thyroid, the pancreas, the liver, and the gastrointestinal tracts of the fetus.

3 – The mesoderm is responsible for the development of the urogenital system, the skeleton, the connective tissues, the muscles, and the bloodstreams in the fetus.

During this week, the placental cells get attached to the linings in the uterus, the uterus linings are responsible for providing the fetus with enough oxygen and other nutrients for its proper growth, and they will also provide the growing embryo with proper blood supply.
