Fetal Development

Yes. The earliest you would be able to detect a heart beat is 5 weeks.

oxygen and nutrition

Nope - breathing is the action of drawing air into the lungs, and expelling waste gasses. Whilst in the womb, the developing foetus draws all the oxygen it needs from the placenta.

The embryo lasts until about week 10 or 11 and then it is known as a fetus.

The blood is "grown" by the fetus along with the organs and bones. The fetal blood supply is separate from the mother's. The two blood systems interact through the placenta - oxygen and food pass though to the fetal blood from the mother, waste products flow from the fetus to the mother.

It depends, because there are many things that can harm your baby or so the fetus. You shouldn't smoke or drink because it can have dificulties at birth or during their first years. If you smoke too much your baby could come out with asthma just like i did. my mother smoked during pregnancy and i have asthma becaus eof that so you definitely do not want to put your child through that. If you fall you will have achance of loosing your baby depending on how far you are.

Brain damage for you and the baby, even death. Stop being dumb.

Approximately nine months, just like humans!

Because your body and the embryo secreat hormones that make you sick sometimes..

No, if you are under a lot of stress or you can lift on something heavy and tear the placenta from the wall or any trauma to the abdomen can cause you to miscarry. It is more common to miscarry before you see/hear a heartbeat.

The structure responsible for nutrient and gas exchange between the mother and the growing fetus is the placenta. The placenta facilitates the transfer of oxygen, carbon dioxide, nutrients, and waste products through its extensive network of blood vessels, connecting the maternal and fetal circulatory systems. This organ plays a crucial role in supporting fetal development throughout pregnancy.

This is typically about 14 inches (35 centimetres)

During the 1st trimester, all the major body organs form. The heart begins to beat at 4 weeks, and by the end of the 1st trimester fetal heart sounds are able to be heard. During the 2nd trimester, the fetus looks like a baby, the sex of the baby can be determined, and sometime between the 16th-20th weeks the mother will begin to feel the baby's movements. The baby will become more active. Hair, eyebrows, and eyelashes develop. During the 3rd trimester, the baby develops the ability to breathe as surfactant is produced. Finger and toe nails form, and the baby continues to grow and create subcutaneous fat. During this time the baby is also able to open and close it's eyes.

what will happen if the fetus stomach is in the middle instead of the left side?

embryonic

At about 24 weeks, your baby's outer, middle, and inner ear — including the cochlea, the snail-shell-shaped tube in the inner ear where vibrations are converted into the nerve impulses we perceive as sound — are well-developed. By 27 to 30 weeks, your baby's ear is mature enough to start to respond to the sounds that filter through to him or her. The sounds, of course, are muffled — and not just by the physical barrier of amniotic fluid and your own body. In his or her fluid-filled home, a baby's eardrum and middle ear can't do their normal job of amplifying sounds. So even sounds that are quite loud to you won't be for the fetus. A fetus' prolonged and repeated exposure to very loud noise — say, an eight-hour-a-day shift in an industrial workplace, where the sound level is more than 90 or 100 decibels (about the same as standing next to a loud lawnmower or a chain saw) — raises the odds of a baby suffering some hearing loss, especially at higher frequencies. Such prolonged noise exposure can also increase the risk of premature delivery and low-birth-weight babies. Extremely intense sound, 150 or 155 decibels (ever stand right next to a screaming jet engine?), can cause similar problems for the baby. Noise is usually considered as detrimental during the pregnancy. In most European countries, health regulations forbid pregnant women to work in surroundings with a level over 80 dB continuous noise and rapid impulse noise changes of 40 dB.

Oh, the chances of survival are quite high! At 27 weeks pregnant, your baby has an 85% chance of survival if it were to be born that week! You are nine weeks ahead of that! Your baby's lungs are fully developed at this stage so I wouldn't worry.

If you mean eggs from birds or chickens, then the embryo uses gas exchange. there are tiny pores in the egg shell where oxygen can go into a small bubble at the top of the inside of the egg. it gets it's food from the surrounding yolk & egg white.

Fingers and toes begin to develop during the first trimester of pregnancy, specifically around the 8th week. By the end of the first trimester, typically around 12 weeks, these digits are more distinctly formed. This process is part of the overall development of the limbs during early fetal growth.

Human eyes begin to develop about 22 days after fertilization! Between weeks 10-12, the eyelids are formed, and are closed; they remain closed until week 27-28, when the fetus can open and close the eyelids. So, the fetus (unborn baby) can see, though it's pretty dark inside there! When they're born, babies can see light and movement, but they can't focus on anything or follow movement with their eyes.

The placenta being attached to both the mother and the fetus, provide important benefits, such as supplying nutrients to the fetus, eliminating waste, and gas exchange.

Learn? No.

Think? It's called a fetus up to week 38 so in the end it can think but it's not something one will remember. Consciously we don't start to remember until we are around 2.

The baby will likely be fine but your skin might be more sensitive and burn more easily
