Fetal Development

Inbreeding results in higher numbers of genetic defects.

Either through the umbilical cord (in the case of a pregnant woman) or by passive smoking.
Nicotine gets into the mothers blood stream which then flows into the baby's blood stream.

A vaginal ultrasound can tell how far along you are. Also a blood test for HCG quants will tell also. Consult your doctor or clinic. It doesn't matter whether or not you have a vaginal ultrasound or one on the abdomen ultrasound is a very good way of seeing how far along you are in pregnancy and making sure that the fetus is developing accordingly if they see any problems in the development they will want to run more tests hope this helps you , Good Luck and God Bless!!!

yes hemophilia can be detected before birth

Everything the fetus needs is provided by the placenta.

Drinking small amounts of alcohol have been proven to NOTbe harmful to an unborn baby....Just don't get trashed...

The embryo starts out the size of a couple cells (microscopic) by the end of the first trimester may be nearly 2 1/2 inches long from crown to rump (CR measurement) and weighs about 1/2 ounce.

The earliest a doctor can get a baby's heartbeat on a Doppler inside the womb is 9 weeks... any earlier and it might not be able to be heard! Hope this helps... on the flip side you should take into account your size. If you are smaller it might happen sooner and if you are larger than it may happen a little later.

It is called lanugo, the skin is also coated with a white greasy like substance called vernix and protects the fetus from the effects of being in the amniotic sac ( bag of water)

No. The heart beat in your neck is yours. In fact it isn't really possible to feel the babies heart beat at all. You can hear it with a monitor and even a stethescope, after the 3rd trimester begins(usually). You will also feel a heart been below your belly button, that ones yours too. A babies heart beat is very fast, approx 120-160 beats per minute. To determine your heart rate, put your first and second finger (pointer and middle) together, over the inside of your wrist, closest to the thumb. Look at the second hand of a watch or clock and count the beats for 6 seconds. Then multiply the number of beats by 10. This will equal your approx. heart rate. This isn't very accurate but it gives you an idea of the difference between your heart rate and your babies.

It's possible, though not likely. 85% of women can see the heartbeat flicker on the u/s at 5-6 weeks, although some women with a higher body mass index cannot. Do not give up hope until your HcG levels have been measured by the doc. Good luck.

A fetus does have amniotic fluid in the mouth, and the lungs. It enters through the nostrils. There is no air in the womb, the baby is surrounded only by amniotic fluid. The baby, once born, has to cough (or cry) out the amniotic fluid before it can breathe the air.

It is an ultrasound scan where the gel is rubbed onto your belly when you are pregnant to monitor the progress and growth of a foetus. they use ultrasound waves to bounce of the foetus and create the picture you see on the screen

Your baby is approximately 6 inches long and weighs 8 1/2 ounces! Check out this website for a picture and a week-by-week update of what your baby looks like!

well since i been doing research on fetuses, my girlfriend is pregnant i believe that a 7 month old fetus can survive preterm birth because of development, so does the 8 month old fetus, but i believe the 8 month old fetus can't survive because it was almost born, i guess. Personally, I haven't heard of this, and can't find it in any of the medical textbooks I have.

An 8 month fetus has more chance of survival than a 7 month old fetus because it is more developed. The weeks just before full term birth, the baby is working on lung development. Neither than 7 month old nor the 8 month old has full lung capacity development... and actually the 7 month old hasn't even started much on this one.

It really depends on any other complications that arise. If the 8 month fetus has more complications, say because of genetics or trauma besides the pre-term delivery, it would have a lesser chance of survival compared to a 7 month fetus that has little or no complications, either genetics or trauma. Both fetus are at risk for pre-mature illnesses and the normal complications that stem from being delivered early.

In either case, medical technology has advanced quite far in these times. Both fetus have a chance for survival with various treatments, medications, machines, and procedures, depending on the needs of the preemie and the stage of development, as well as post-partum circumstances that arise. It is still true, however, that the further along you can carry the baby, the better chance of survival it has because it has been able to be more developed. This is why, if you are too early, and you have true labor pains, the doctor will give you medication to stop the labor and thus give the baby more time to develop in utero.

At 31 weeks the top of the uterus is approximately mid-way between the belly button and the bottom of the breast bone. How big you look depends on a lot of things, how good your abdominal muscles are, how tall you are, how slim or big you are/were etc. I have looked after several women who hardly appear to be pregnant at all, and a couple of young girls who have concealed their pregnancies even from their families until they have delivered full-term babies.

6 inches crown to rump 10 inches if streched head to toe

Yes, I went in for an ultrasound on 09/24/09 and they told me I was 6 weeks and 4 days along. the baby's heart rate was 138bpm and I could hear it with the abdominal ultrasound and the transvaginal.

However, every pregnancy is different. Godd luck!

18-22 days 18-22 days

== You can see the hearbeat at your FIRST ultrasound appointment.....it won't look like much, just a bright, very fast flutter on the screen, but alas that is your "little one"! My wife and I saw our baby's heart beat with a transvaginal probe a little less than 4 weeks after conception, which is considered 5-6 weeks gestation.

it is possible if scientists ever found a way and our body got used to it

(ex. your has to get use to a kidney sometimes your body rejects it )

A normal pregnancy lasts 41 weeks from fertilization to term. Therefore; gestation days would calculate to 287.

9 months well a fully completed baby would take 9 months but however some babies are born prematurly early.

Answer Depends on what is meant by 'complete'. Human gestation normally lasts 9 months, but lots of people would say it is human before it is born. For example, is a fetus not completely human at 8.5 months or a week before the due date? Also after it is bornthe baby is totally dependent on the mother - and some people would say that it is not complete until it is able to think for itself and live on its own. Of course that would mean that those who are mentally handicapped are not completely human - and that's Nazi thinking. So - gestation is usually 9 months but the expression completely human is open to argument.

yess my babies heartbeat was 176 at my first ultrasound. It slows down the farther along you get until its ready to beat on its own without your help after you have the baby.

oh yes you definitely can. at this point the babys movement should become more tense
