After the zygotic human stage, is the embryonic human (up to gestational week 18 and organ development), then fetal human (beyond 18 weeks gestation)—each a proper stage and station of human development lacking no “born-ness.”
Fetuses are indeed human beings, not just clusters of cells. Scientific advancements illustrate their development, showcasing unique DNA and essential life processes that affirm their humanity long before birth. Do fetuses have human DNA from conception? Fetuses have human DNA from conception.
A human life may be considered a human person at fertilization. On the other hand, others attribute personhood once the physical appearance of a fetus resembles the mature human form at about week 9 of gestation during embryogenesis.
Embryologist Scott Gilbert states: There is no consensus among biologists as to when personhood begins. Different biologists have proposed that personhood begins at such events as fertilization, gastrulation, the acquisition of an EEG pattern, and birth.
The average fetal heart rate is between 110 and 160 beats per minute. It can vary by 5 to 25 beats per minute. The fetal heart rate may change as your baby responds to conditions in your uterus. An abnormal fetal heart rate may mean that your baby is not getting enough oxygen or that there are other problems.

Is a fetus conscious?
It reacts to touch, smell, and sound, and shows facial expressions responding to external stimuli. However, these reactions are probably preprogrammed and have a subcortical nonconscious origin. Furthermore, the fetus is almost continuously asleep and unconscious partially due to endogenous sedation.
In humans, fetal DNA has been detected in maternal blood as early as four weeks and five days after conception and both fetal cells and DNA are consistently detected from seven weeks.
Other religious views are that ensoulment happens at the moment of conception; or when the child takes the first breath after being born; at the formation of the nervous system and brain; at the first detectable sign of brain activity; or when the fetus is able to survive independently of the uterus (viability).
All human individuals—whether they have an XX, an XY, or an atypical sex chromosome combination—begin development from the same starting point. During early development the gonads of the fetus remain undifferentiated; that is, all fetal genitalia are the same and are phenotypically female.
For instance, we can regard the fetus which is 20 weeks or more as a person. Alternatively, we can refer to a fetus of 12 weeks or more as human being.
A zygote is capable of splitting to give rise to identical twins. Since the zygote cannot be identical with either human being it will become, it cannot already be a human being. Parallel concerns can be raised about chimeras in which two embryos fuse.
Early Christian writings (the Didache in particular) explicitly condemn abortion and were written around the same time as the gospels. It is true that it is not explicitly mentioned in the Bible, but to say that Christianity has never opposed or had nuanced opinions on abortion until modern times is false.
Fetuses are asleep almost all the time until third trimester , when they're awake 2-3 hours per day. It's unrelated to mom's sleep, although people think it is because they notice their movement more when laying down and trying to sleep.
With each anxious moment, each peaceful breath, and each surge of joy, your baby is experiencing these emotions alongside you. The truth is that your nervous system—the master controller of your stress response, emotions, and physical sensations—is directly wired to your baby's developing brain and body.
At 26 to 30 weeks, a fetus is rapidly developing its brain controls and some body functions. The fetus has eyelids which open and close and has a rapidly developing respiratory system. At 30 to 32 weeks, a fetus has increased central nervous system control over body functions and rhythmic breathing movements.
During fetal development, the heart begins to form quite clearly and beats around 22 days after conception, usually before the mother realizes she is pregnant.
(FEE-tus) An unborn offspring that develops and grows inside the uterus (womb) of humans and other mammals. In humans, the fetal period begins at 9 weeks after fertilization of an egg by a sperm and ends at the time of birth.
The baby/fetus occupies the space of the uterus (womb) which, anatomically, is considered external to the mother's body. The mother eats and breathes for the baby/fetus via a large capillary bed that interfaces with the placenta leading to the umbilicus. Mother and baby/fetus have different genetic codes.
The structure that is most analogous to the uterus in women is the epididymis in men. The epididymis is an organ made up of a highly coiled tube that stores the sperm produced by the testes. Sperm undergo maturation in the early sections (the head and body) of the epididymis and are stored in the tail section.
Babies can't cry out loud of course until they're born. In the womb, babies are totally immersed in amniotic fluid, so there is no air in the lungs and air is needed to produce sounds. Once they are born they can fully expand their lungs, taking in air and letting out those first few wonderful cries.
Yes, babies can feel belly rubs, with touch sensitivity beginning around the 7th week of pregnancy. Fetuses actively respond to maternal belly rubs with distinct movements of their arms, heads, and mouths.
