The placenta is a critical organ that develops in the maternal uterus during pregnancy to support the fetus. It connects to the fetus via the umbilical cord in order to allow nutrient transport, waste excretion and gas exchange between mother and fetus. [2] The morphological features of the placenta differ among species, but the function is ...
Maternal placentophagy is defined as "a mother’s ingestion of her own placenta postpartum, in any form, at any time". [1] Of the more than 4000 species of placental mammals, most, including herbivores, regularly engage in maternal placentophagy, thought to be an instinct to hide any trace of childbirth from predators in the wild.
The placenta may adapt to maternal malnutrition in an effort to support fetal development and protect against adverse nutritional exposures. In pregnant mice, undernutrition and high fat diets have been shown to alter both placental size and structure, including the expression of key transport systems. [28]

The following have been identified as risk factors for placenta previa: Previous placenta previa (recurrence rate 4–8%), [13] caesarean delivery, [14] myomectomy [10] or endometrium damage caused by D&C. [13] Women who are younger than 20 are at higher risk and women older than 35 are at increasing risk as they get older.
[36] [34] During pregnancy the placenta concentrates B 12, so that newborn infants have a higher serum concentration than their mothers. [33] What the mother-to-be consumes during the pregnancy is more important than her liver tissue stores, as it is recently absorbed vitamin content that more effectively reaches the placenta.
Eating fish while pregnant may reduce the likelihood that a child is diagnosed with an autism spectrum disorder by 20%, a new study found. Taking fish oil supplements did not produce the same result.
