A process where a long thin tube is used to withdraw fetal cells from the fetal side of the placenta is?
It is episitomy
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.
Briefly describe how are amniocentesis and chorionic villi sampling are used in genetic screening?
Amniocentesis involves taking a sample of the amniotic fluid and checking the fluid for fetal tissue, metabolites, and other markers that would indicate that there is a problem with fetal development. Fetal genetic testing can be performed on the fetal cells in the amniotic fluid. Chorionic villi sampling essentially involves collecting a specific part of the placenta for genetic analysis. Since the placenta is the same genotype as the fetus it is possible to make a genetic diagnosis of the fetus based on analyzing the placenta. Chorionic villi sampling is less invasive and therefore less likely to cause fetal distress.
Fetal blood that passes through the ductus venosus is relatively High in oxygen and nutrients?
The ductus venosus shunts most of the left umbilical vein blood flow directly to the inferior vena cava. This allows relatively highly oxygenated blood from the placenta to bypass the liver and get to the fetal brain.
What supplies food and oxygen for the developing embryo?
The developing embryo is nourished by the yolk sack until implantation. Upon implantation the placenta begins to develop, the placenta acts as the fetal lung , it transports oxygen to the fetus and carbon dioxide away from the fetus via the umbilical cord. The placenta also provides stored carbs for the developing fetus.
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
What is circumvallate placenta?
Its a placentation abnormality .Placenta got a fetal site .Fetal site which has a central depression is circumvallate 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).
What is the fetal equivalent of lungs and liver?
Placenta
What side of the placenta that is smooth and shiny?
Fetal surface.
What carries fetal blood to the placenta?
umbilical arteries
A process where a long thin tube is used to withdraw fetal cells from the fetal side of the placenta is?
It is episitomy
Where in a mother does a fetal pig form?
As in most mammals, the fetal pig will form within the placenta in the uterus of the mother.
What age does the heart of the fetal develops?
6 week
What human organ brings together maternal and fetal circulation?
placenta
What is A process where a long thin tube is used to withdraw fetal cells from the fetal side of the placenta is?
It is called chorionic villi sampling.
