Fetal Development

the wall of the uterus where oxygen, nutrients, and waste exchange takes place between the mother and fetus

Fetuses need oxygen because (like us) they are made up of cells that use aerobic metabolism. Aerobic metabolism is a system used by cells to make cellular energy out of glucose (sugar) and Oxygen. Fetuses, which start out as one unique cell, need oxygen because they have the same machinery.

If for some reason they didn't get enough oxygen they (like us) would start producing acid and 1/16th of the energy they were producing before and the cells would die.

Put a gun to your head and pull the trigger. That will effectively "exterminate" the fetus growing inside of you. I hope this answer helps...

a developing fetus receives nourishment from the placenta, which is burrowed into the uterus

Embryos are genotypically a boy or a girl at the time of conception. The chromosomes they inherit make them either XX(girl) or XY(boy). Because a female is XX, she will always contribute an X chromosome, but because a male has both, X and Y (XY), the male could either contribute an X chromosome or a Y chromosome.

The safest way is to go to a clinic and have the procedure performed by a professional. However, that is serious decision. Prior to making that decision, please consider all of the short and long term consequences for your decision. There's much more to an abortion than just the termination aspect. There are mental, emotional, spiritual, and physical pains that you will experience. Additionally, the pains can sometimes be long term and permanent. I am not suggesting that you don't, however, I am suggesting that you consider all the consequences, and ask yourself, if you are strong enough to deal with and handle the long term realities of abortion--especially the facts that are not shared with a lot of women. Please research thoroughly, consider all of your options, and then make your decision. There are a lot more terrible things out there than being pregnant--children bring so much joy in this world. They are innocent, happy, and peaceful--and we experience all of this once we see them. Ask me how do I know. The fetus I considered aborting is now 27 years old and she is the best thing that could have ever happened to me. When the doctors diagnosed me with a terminal disease, it was her support, love and care that helped to to heal and I am still alive to share this with you today. Whatever decision you make, I will pray for you and always know, no matter what you do, GOD STILL LOVES YOU. Whatever decision you make, accept the consequences and continue on with your life. Do not get stuck--but get star struck and move into your destiny. GOD HAS A PERFECT DESTINY FOR YOU. You are sooo very Precious

The yolk sac eventually becomes part of the embryos midgut and is not part of the amnioyic sac. They are separate structures. It is possible to have an empty amniotic sac called a blighted ovum but it is not possible to have a yolk sac but no amniotic sac.

at 10 1/2 weeks a babies heartbeat should be between 140 and 150

Not all pregnancies are the same, i should know, I'm having my 6th one. From what i was told with my pregnancies, was that for boys, the normal beat would be between 130/139 and for girls 140/150. If it's much over or much under, only your ob doctor can tell you if it's ok or not. I'm 30 weeks now and my doctor told me the beat was 152, i was worried because my other daughter didn't have it that high and on top of that, he told me i was having a boy. My ob says that as long as the heart beat stays between 120 to 160, it should be fine. Again, it all depends on your doctor. This early in the pregnancy, i definitely would suggest to get a pro's opinion.

ACOG expanded their guidelines to include heartbeats from 110-160 as a normal range during pregnancy.

Although, as you get closer to term, more important factors contribute to good fetal heart tones (FHTs) than just heart rate including variability, absence of decels, presence of accels, and a reactive strip.

Apparently, in infancy, it is very hard to tell

No, with a Doppler stethoscope it can be heard at approx. 8-10 weeks in a thin woman.An ultrasound machine can see the fetal heart at 6-8 weeks depending on the qualiity of the machine. The fetal heart is way to small to feel early in the pregnancy, in fact, it cannot even be felt at full term.

Chewing tobacco when pregnant is no different that smoking it is a harmful chemical that may cause birth defects. Just because you chew it doesn't mean the fetus will not be exposed to it. Also its gross so theres that too.

At twelve weeks the emryo is then called a fetus because of the process of organogenesis, which is the process of organ formation. The brian has developed by this point but will not develop further until much later in the pregnancy. The heart has usually started to beat by this point as well. at 10 weeks

You probably won't feel your baby kick until around week 16 and 22, even though the baby has been moving since week 7 or 8. You may have already witnessed these movements during an ultrasound. This is often felt as a fluttering feeling or a grasshopper walking across your belly during the first movements.

This is often felt as a fluttering feeling or a grasshopper walking across your belly during the first movements.

At first, you will not notice many kicks, and this is okay. One day you may notice the baby is quite active and feel no movement at all the next day. It is nothing to worry about until you have movement on a regular basis and should keep track. If you notice a lack of movement, you should contact your doctor soon (don't panic this doesn't mean you are having a miscarriage, just room for concern and you doctor may want to induce you early to protect the health of you and your baby).

There are many antibodies passed to the fetus. Any and all that she was exposed to would be passively passed to the fetus. These are passive in that the newborn will have to make his own later in life but will keep him from harm for about 6 months.

For the first 8 weeks the developing human is called an embryo after that it is called a fetus.

At the ultrasound there will be no heartbeat or movement. If you are further along in your pergnancy and normally feel the baby move, you won't be able to feel him/her move anymore. If you are at the beginning of pregnancy, you will bleed heavily probably with some pain

I have to say if you have not m/c it is likely that the 8 week u/s just did not detect a hb. Plainly said, growth happens at an alarming rate during the first trimester and its possible that you just didn't see that heart rate at your 8wk because it wasn't ready yet. You also need to take in account the possibility of error in fetal age if you didn't know your exact ovulation or LMP.

They can do, it is around the borderline. The baby will spend a very long time in the neonatal intensive care unit and usually will have to have support with breathing since the lungs are not fully developed.

Without the mother having any circulation or life support, it wouldn't last very long. They baby would begin to suffocate. After 4 minutes, neurological damage would begin. In about 10 to 15 minutes, there would be fetal death.

Eclampsia

a baby will be either a boy or a girl long before it becomes a fetus. A woman's egg carries an X chromosome (women are XX). However, since men are XY, a single sperm cell will carry either an X or Y chromosome. Depending on which sperm cell enters into the egg will result in either the a boy baby or a girl baby.

The uterus, although the egg is fertilized in the fallopian tube
