What else can I help you with?
What is the name for the protective structures that form around an embryo?
Placenta.
What are two associated structures in the placenta?
umbilical cord and fetus
What structures ultimately forms the placenta?
Chorionic villi & Decidua Basalis
The allantois membrane and which of these form the placenta?
The allantois membrane and the chorion form the placenta in mammals. The chorion is the outermost fetal membrane that encases the embryo and later fuses with the maternal tissue to form the placenta.
What two tissues does placenta form?
trophoblasts/chorionic villi and the uterus form the placenta
When does the amniotic sack and placenta form?
The amniotic sac and placenta begin to form shortly after conception. The amniotic sac develops from the outer membranes surrounding the embryo, starting around the second week of pregnancy, while the placenta begins to form from the trophoblast cells that surround the developing embryo around the same time. By the end of the first trimester, both structures are well-established, providing essential support and protection for the growing fetus.
What two structures are part of the after birth?
The two structures that are part of the afterbirth are the placenta and the umbilical cord. The placenta facilitates nutrient and gas exchange between the mother and the fetus during pregnancy, while the umbilical cord connects the fetus to the placenta, providing a lifeline for nutrients and waste removal. After childbirth, these structures are expelled from the body, marking the end of the delivery process.
What are the two structures that produce human chorionic gonadotropin?
placenta and germ cell
The allantois membrane and what form the placenta?
chorion
What is the plural form of placenta?
placentae or placentas
What three structures protect and nourish the developing embryo?
Placenta, amniotic fluid and umbilical cord.
What causes umbilical cord to attach on side of placenta?
The umbilical cord connects to the Placenta once it is in form to attach
