What else can I help you with?
What is my maternal grandfather's side of the family called?
Your maternal grandfather's side of the family is referred to as your maternal grandfather's lineage or maternal grandfather's family.
What does family of mother's side is called?
Your mother's family is your maternal family.Family history traced through the mother is called the matrilineal history.
What is the membrane that forms the embryonic side of the placenta?
The placenta is completely formed by 10 weeks, by the joining of the decidua basalis (maternal side) and chorionic villi (fetal side). The chorion and amnion are the placental membranes. The Chorion is the membrane furthest from the embryo, and the amnion in the inner layer that is closest to the embryo.
What human organ brings together maternal and fetal circulation?
placenta
Does endometrium participate in the formation of the placenta?
No, the endometrium does not directly participate in the formation of the placenta. The placenta is formed from the embryonic tissue (trophoblast) and the maternal tissue (decidua) lining the uterus, not from the endometrium.
What is duncan placenta?
Duncan placenta, also known as the Duncan's placenta, is a type of placenta observed in certain mammals, particularly in some species of bats. It is characterized by a more invasive and less efficient connection between the maternal and fetal tissues compared to other placental types, such as the deciduate placenta. This type of placenta has implications for nutrient transfer and maternal-fetal interaction. The term is named after the researcher who studied its characteristics and implications in reproductive biology.
The part of the uterus that will become the maternal portion of the placenta?
The decidua basalis portion of the endometrium
What is a prenatal infection?
A prenatal infection is a maternal infection that is transmitted to the fetus through the placenta.
What is the placenta barrier?
The placenta is an organ that connects the developing fetus to the uterine wall. The placenta supplies the fetus with oxygen and food, and allows fetal waste to be disposed via the maternal kidneys. The placenta develops from the same sperm and egg cells that form the fetus, and functions as a fetomaternal organ with two components, the fetal part (Chorion frondosum), and the maternal part (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.
How does blood pass across the placenta?
Blood does not directly pass between the mother and fetus across the placenta; instead, the placenta facilitates the exchange of nutrients, gases, and waste products through a process called diffusion. Maternal blood circulates in the intervillous space, surrounding the chorionic villi, which contain fetal blood vessels. Oxygen and nutrients diffuse from the maternal blood into the fetal blood, while carbon dioxide and metabolic waste move in the opposite direction. This efficient exchange supports fetal development without mixing maternal and fetal blood directly.
Combination of embryonic and maternal tissue?
The placenta results from the combination of embryonic and maternal tissue. The fetal portion of the placenta develops from the outer layer of the blastocyst, while the maternal portion is derived from the lining of the uterus. Together, these tissues form a vital connection between the developing fetus and the mother to facilitate nutrient exchange and waste removal.
