Fetal development chart at nine weeks of pregnancy

Diagram of the baby's development process at 9 weeks of pregnancy. By the 9th week of pregnancy, the test tube embryo has taken shape and is about 25mm long. Only then can it be called a "fetus" in the true sense. So, what is the actual fetal development chart at nine weeks of pregnancy? Let's have a simple understanding of this issue. I hope the following points will be helpful to everyone!

By the 9th week of pregnancy, the test tube embryo has already taken shape. From today on, your test tube embryo can be called a "fetus" or "baby". In order to accept the new resident, your uterus will swell greatly. Now the size of the fetus is about 2.5 cm, and there are certain changes in many parts of the fetus. For example, the tail of the embryo has disappeared. Now all the baby's organs, muscles, and nerves begin to work. The arms begin to bend slightly from the wrists, the feet begin to get rid of the webbed surface, and the eyes begin to cover.

At 9 weeks of pregnancy, let's take a closer look at the baby's body transformation.

The tail of the fetus during the test tube embryo period has disappeared, and the whole fetus has changed. Look! We have just started calling the test tube embryo a "fetal baby." This is a critical point and a key period of the entire pregnancy, from which the fetus begins to grow and develop its organ system. At 9 weeks, the fetus is about 25mm and many parts of the fetus have changed. Now all the neuromuscular organs of the human body start working. The baby's eyes begin to cover up, the arms are bent at the wrists, and the feet begin to loosen their webbed surfaces, so that the ankles can be seen. The arms are longer and the elbows have already appeared. Although you cannot determine the baby's gender through B-ultrasound at this moment, the baby's reproductive organs are already growing and developing.

Next, let’s take a closer look at it.

Fetal body transformation

The fetus's brain, eyes, mouth, ears, digestive tract, hands, and feet begin to grow and develop.

The head looks particularly large in the whole body, almost accounting for most of the body length. The cheeks, jaw, upper eyelids and earlobes have grown and formed, and the face looks more like a face. The little tail has completely disappeared, and the eyes, fingers and toes are clearly visible.

Because the skin of the fetus is completely transparent, the formed liver, ribs and subcutaneous blood vessels can be clearly seen through the skin, and the heart, liver, and intestines are more developed.

The fetus itself has developed a blood circulation system, and its kidney function has become relatively developed. It now has a urethra and can excrete a little urine, but its bones and joints are still growing and developing.

Embryonic transformation

The embryo has already taken shape. The fetus is swaying in the amniotic fluid of the pregnant woman, and seems to be very happy. Sometimes the upper and lower legs can be flexed and extended alternately, and the hands can reach the face, which shows that the spinal nerves and other nerve centers are very developed.
