How does human fetus taste
Development from embryo to baby
Pregnancy weeks at a glance
At the moment the embryo is still a cell ball about 2 mm in size. The cells are already sorted according to the structures that will later develop from them.
In the 5th week of pregnancy, the embryo looks roughly like a tadpole and is about 3 mm in size. The heart starts beating. Very rough facial features (e.g. mouth and nostrils) develop.
The embryo is about 5 mm in size. The extensions that later become arms and legs form paddle-like structures - the later hands and feet. The embryo is now making its first movements.
The embryo is approximately 1.2 cm. The organs become more complex and fingers and toes are formed, which are initially webbed.
In the 8th week of pregnancy, your child is no longer called an embryo, but a fetus. Officially, it keeps this name until it is born. It is about 1.6 cm tall and 1 gram in weight. The organs, nerves and muscles all start working.
The fetus is approximately 2.3 cm and weighs 2 grams. He already has eyelids, but they remain closed for the time being. Elbows and ankles are formed. The development of the genitals also begins now.
The fetus is about 3 cm tall and 4 grams in weight. He can now swallow and develops details such as fingernails and downy hair on the skin.
Your child is about 4.1 cm tall and weighs 7 grams. Although it is so tiny, all the important organs and body parts are already in place. In the next few months they will differentiate, grow and sometimes change their position.
The fetus is now about 5.4 cm tall and 14 grams. Ears and eyes migrate to the correct position on the head. The brain now forms connections between the nerve cells.
Your child is about 7.5 cm tall and weighs 23 grams. He now has a fingerprint that is unique in the world (even if it is a multiple pregnancy).
The fetus is approximately 8.7 cm and weighs 43 grams. In the 14th week of pregnancy, he can already grimace, grasp and blink - but not yet see, the eyes are not yet developed enough for that.
The fetus is about 10.1 cm tall and weighs 70 grams. He's not breathing yet, but he has frequent hiccups. All joints on the arms and legs are fully developed.
The fetus is approximately 11.6 cm and weighs 100 grams. He is now slowly using his unfinished lungs, but he can only 'breathe' amniotic fluid. Oxygen is supplied through the umbilical cord.
The fetus is about 13 cm long and 140 grams. Big enough that you could feel its movements for the first time. You can now hear your heartbeat with a special stethoscope.
The fetus is approximately 14.2 cm long and weighs 190 grams. He is now swallowing amniotic fluid. The taste buds develop in the mouth.
Your child is approximately 15.3 cm long and weighs 240 grams. The regions for sensory perception in particular are developing in the brain: smelling, hearing, tasting, seeing and feeling. So far, however, the fetus can only taste and feel.
The fetus is around 16.4 cm and weighs 300 grams. It is now covered in what is known as cheese smear. This whitish substance contains a lot of fat and protects the skin from the amniotic fluid.
From the 21st week of pregnancy, the fetus is measured from the top of the head to the toes - up to the 20th week, measurements are taken from the top of the head to the rump. It is approx. 27 cm long and weighs 360 grams. Your baby can hear now. Above all, it hears heart and intestinal noises as well as the voice of mom, but also loud noises from outside penetrate to it. The iris also develops in the eye.
The fetus is approximately 28 cm and weighs 430 grams. The proportions of limbs, head and torso are already correct, but there is still a lack of fat. Because of this, the baby is still thin and wrinkled.
The fetus is now approximately 29 cm and weighs 500 grams. The hearing continues to develop and refine.
The fetus is about 30 cm tall and weighs 600 grams. His alveoli are now fully developed.
The fetus is about 35 cm tall and weighs 660 grams. Although the visual apparatus is not yet fully developed, it can now distinguish between light and dark.
The fetus is around 37 cm tall and weighs 750 grams. The eyes are now beginning to open properly for the first time.
The fetus is about 37 cm tall and weighs 900 grams. The eyes can now open and close. In addition, your baby sleeps at regular intervals.
The fetus is now around 38 cm tall and 1 kg. He can smell now because the nostrils are now free.
The fetus is approximately 39 cm and weighs 1.2 kg. His bones are now getting harder by storing calcium.
The fetus is about 40 cm tall and 1.3 kg. The visual apparatus is more and more finely differentiated. The eyes can now be moved in the eye socket. A surface film forms in the lungs, which is necessary for breathing.
The fetus is approximately 41 cm and weighs 1.5 kg. He now moves less because it is slowly getting tight in the stomach. It dreams while sleeping.
The fetus is approximately 42 cm and weighs 1.7 kg. In male fetuses, the testicle has now moved from the abdomen into the scrotum. Some fetuses already have thick hair on their heads.
The fetus is now approximately 44 cm and weighs 1.9 kg. He's probably upside down by now. His skin is smoothing out and is now less reddened.
Week 34 - 40
The fetus is about 45 cm tall and 2.1 kg at week 34. The development of the fetus is now basically complete. It just keeps growing and getting heavier. It will also rotate and sink into the pelvis for the next few weeks of pregnancy. By the 40th week, it is about 51 cm tall and 3.5 kg.
