Viability is defined as the ability of fetuses to survive in the extrauterine environment….
Skipping breakfast could lead to extended periods of lower than normal nutrients in the woman's blood, leading to a higher risk of prematurity, or other birth defects in the fetus.
A fetus (or foetus, fњtus) is a developing mammal or other viviparous vertebrate, after the embryonic stage and before birth.
A developing fetus is highly susceptible to anomalies in its growth and metabolism, increasing the risk of birth defects.
The preferred spelling in the United States is fetus, but the variants foetus and fњtus persist in other English-speaking countries and in some medical contexts, as well as in some other languages (e.g., French).
Especially since the 1970s, there has been continuing debate over the "personhood" of the human fetus.
Fetal hemoglobin enhances the fetus' ability to draw oxygen from the placenta.
The word fetus is from the Latin fetus, meaning offspring, bringing forth, hatching of young (Harper 2001).
Maternal factors include maternal weight, body mass index, nutritional state, emotional stress, toxin exposure (including tobacco, alcohol, heroin, and other drugs, which can also harm the fetus in other ways), and uterine blood flow.
Fetal factors include the fetus genome, nutrient production, and hormone output.
Blood from the placenta is carried to the fetus by the umbilical vein.

The ability of a fetus to feel pain is often part of the abortion debate.
The plural is fetuses (foetuses, fњtuses) or, very rarely, foeti.
The fetus of most mammals develops similarly to the Homo sapiens fetus.
The fetus is not as sensitive to damage from environmental exposures as the embryo was, though toxic exposures can often cause physiological abnormalities or minor congenital malformation.
After birth, a human fetus becomes an infant, or a "neonate" in the first month.
