Q

what is the endometrium lining

A

functions as the lining for the uterus. During the phase of the menstrual cycle, the endometrium thickens in preparation to accept a fertilized ovum. If an ovum was not fertilized, then the thickened lining is expelled during menstruation

25
Why do teens have a higher risk of birthing low weight babies

41
is gestational diabetes curable
it resolves when the baby is born

what is the umbilical cord
the connection between the fetus and the placenta that passes oxygen and nutrients from the mother to the child and returns waste products back to the mother
58
what is the placenta
an organ attached to the endometrium lining that filters and transfers nutrients and oxygen to the fetus
59
what is amniotic fluid
