Sentences with phrase «placental cells»
Placental cells are cells that are found in the placenta, which is an organ that forms during pregnancy inside a woman's uterus to support the growth and development of the growing baby. These cells help provide essential nutrients and oxygen from the mother's blood to the baby, and also remove waste products from the baby's blood. Full definition
