Week 8: Development of Internal Organs of Fetus

Week 8: Development of Internal Organs of Fetus

Are you aware of the developments that a baby undergoes during the 8th week of pregnancy? Take a quick look at the developments that are expected during this week.

Development of Internal Organs

This is an important week as most of the internal organs like the heart, brain, liver, lungs, kidneys and guts have developed in their basic forms even though they have not taken their final shape as yet. The next eight days are crucial for the development of the eyes and the inner ear, which is responsible for balance and hearing. You can just about see the outer ears taking shape although they are not fully grown as yet.

Development of Facial Features 

The eyes are covered by a temporary skin, which will ultimately open up to create the eyelids. The tip of the nose is visible now as the nostrils have formed. The tongue has appeared and the two sides of the jaw are coming together to shape the mouth. Once the upper and lower jaws begin to fuse, the fetus will be able to open his mouth and suck or chew. But hold on right there. Your baby is not ready for toffees as yet.

Development of Legs and Arms

The baby's leg and arm bones are becoming harder and growing longer and the shoulder, hip, knee and elbow joints are forming this week. Even the fingers and toes are more obviously apparent right through the webs of skin.

Other Features of the Baby this Week

The heartbeat has regularized and the pumping capacity has increased. You can see a network of blood vessels running through this little body through the transparent paper-thin skin. The face is fairly visible though the head seems disproportionately large in comparison to the body, which looks like a fish. Your baby is just one inch or 2.5cm long. And even though this tiny creature moves around a lot, you will not be able to feel her as yet.

Prenatal Visits

You can expect a long conversation with your doctor while visiting for the first time. Your healthcare provider is now busy filling up the paper works and also seeking a lot of information about your health and family history. The ultrasound scans shall reveal heartbeat of your little one and you shall also come to know if you are carrying twins, triplets or a single child. The different paper works involved shall also include registration of your baby by the government officials. This shall help your baby get her birth certificate. You, by the way must be excited to be half way through your first trimester at this week.

Other Developments in the Baby

This week of pregnancy signifies plenty of things. The embryo is at the end of embryonic stage and is preparing to begin a fetal stage. This is the time when she shall lose the tail. The fetus is almost the size of a bean now. With growth and development your baby shall find it difficult to fit into the available room. The gonads are developing into either the ovaries or the testicles.

Body Changes and Pregnancy Symptoms

Your body has gone through so many changes now and you can expect changes to happen outside your body as well. Your uterus is growing in size to accommodate your growing baby. Your breasts too shall get even more sensitive and start preparing for lactation. You may find the area surrounding your breasts turning dark because of increased blood supply. However, you must be informed that this might not happen with everyone.

Hormonal changes result in darkening of the nipples and skin around your breasts. Your nipples may also turn bigger in size with development of Montgomery tubercles. You may also notice discharge of yellowish thick substance called colostrum from your nipples. Again this is not the case with all women. Some may notice it in the later stages of pregnancy and some may not even experience this symptom. Pain or cramps in abdomen may also result from growth of your uterus.

Do not forget to take your prenatal supplements, which constitute a very important part of prenatal care.
