Acting as an excretory organ


Acting as an endocrine organ

Functions of the placenta

Monozygotic twins must have the same blood type and dizygotic twins may have the same blood type, but don't have to

These statements are true since blood type is an inherited trait

Second stage of labor

Time from maximal cervical dilation until the baby exits through the vagina

Placenta previa

Blastocyst implants too close to the cervical opening

Abruptio placentae

Blastocyst implants in the upper portion of the uterus and can cause a life threatening situation
