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.
A process where a long thin tube is used to withdraw fetal cells from the fetal side of the placenta is?
The process you are describing is known as chorionic villus sampling (CVS). It is a prenatal test that involves taking a small tissue sample from the placenta to test for genetic disorders in the fetus.
What is the average weight of the placenta?
The average weight of a placenta is between 1-2 pounds. Variations in weight can occur due to factors such as gestational age, maternal health, and fetal size.
What is area of gas exchange in fetus?
this is the function of the placenta, the mothers blood flows through capillaries that run very close to capillaries filled with the fetus' blood and the gases diffuse across due to the higher oxygen affinity of fetal haemoglobin.
What is the site of fetal development?
Fetal development primarily occurs within the uterus, specifically within the amniotic sac and placenta. The amniotic sac contains amniotic fluid that surrounds and protects the fetus, while the placenta provides oxygen and nutrients to the fetus and removes waste products.
The extraembryonic membrane that forms the fetal portion of the placenta is the?
The chorion.
What is a metabolically active organ that develops as an interweaving of fetal and maternal blood vessels embedded in the uterine wall?
placenta
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.
What is circumvallate placenta?
Its a placentation abnormality .Placenta got a fetal site .Fetal site which has a central depression is circumvallate placenta
What structure of the mother does the fetal pig develop?
The fetal pig develops within the uterus of the mother, where it is nourished and protected by the placenta. The umbilical cord connects the fetus to the placenta, allowing for the exchange of nutrients and waste between the mother and the developing piglet.
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).
Why does the mass of the placenta increase as the foetus develop?
The mass of the placenta increases as the fetus develops to support the growing fetus' nutritional and oxygen needs. This increase in mass is essential for the placenta to effectively exchange nutrients, waste, and gas with the mother's bloodstream to support the fetal growth and development.
How nutrients oxygen and waste are exchanged between the fetus and the mother?
Nutrients, oxygen, and waste are exchanged between the fetus and the mother through the placenta, a temporary organ that develops during pregnancy. The mother's blood containing nutrients and oxygen passes through the placenta, where it comes into close contact with the fetal blood vessels. Through diffusion and active transport processes, nutrients and oxygen are transferred from the mother's blood to the fetal blood, while waste products such as carbon dioxide are transferred from the fetal blood to the mother's blood for elimination.
What is the fetal equivalent of lungs and liver?
Placenta
In the mammalian fetus where does fetal blood exchenge carbon dioxide for oxygen?
In the mammalian fetus, the exchange of carbon dioxide for oxygen occurs in the placenta. The placenta is a temporary organ that develops during pregnancy to allow for the transfer of gases, nutrients, and wastes between the maternal and fetal bloodstreams. Oxygen from the mother's blood diffuses into the fetal blood, while carbon dioxide from the fetus diffuses into the mother's blood for elimination.
What side of the placenta that is smooth and shiny?
Fetal surface.
What is the site of fetal development in female?
Fetal development in females occurs in the uterus, where the fertilized egg implants, grows, and develops into a fetus. The uterus provides a protected environment for the fetus to receive nutrients and oxygen through the placenta, allowing it to grow and mature until birth.
