What is the fetal equivalent of lungs and liver?
Placenta
How does the placenta acts as the lungs for the foetus?
the blood from the mother runs alongside the blood from the foetus ;the mother's blood carries food and oxygen to the baby .The oxygen reachs the lungs and carbon dioxide +waste exits through the umbilical cord . Although they run beside each other they never mix.
Why is the placenta like a lung?
The placenta and lungs both facilitate the exchange of gases - the placenta allows oxygen and nutrients to pass from the mother's blood to the fetus, while removing waste products, similar to how the lungs exchange oxygen and carbon dioxide with the blood. They both play a crucial role in maintaining the health and development of the respective organisms.
Do identical or non-identical twins share a placenta?
do identical or non identical twins share the same placenta
When the lungs do not function in a fetal pig what takes over their function?
The placenta. Deoxygenated blood flows to the placenta where the carbon dioxide is removed and oxygen added. Oxygen rich blood returns to the fetus. Blood is carried to and from the fetus by the umbilical cord.
Are twins sharing same placenta identical?
no they do not.
What is it called when the placenta is birthed before the fetus?
This condition is called Placenta Previa. With placenta previa, the placenta grows on the lower part of the uterus partially or totally covering the opening of the cervix. The placenta should form at the top of the uterus, above the baby. With a normal pregnancy, the baby would be born first, then the placenta. With placenta previa, the placenta would be delivered first. Women with placenta previa require a c-section because as soon as the umbilical cord comes into contact with oxygen, the baby will automatically breathe with his lungs. Delivering the placenta first puts the baby at risk of suffocation in the womb.
Do twins share the same placenta?
No, twins can either share the same placenta (monochorionic) or have separate placentas (dichorionic), depending on whether they are identical or fraternal twins.
How does oxygen travel from the air to the foetus?
Through the mother's lungs into her bloodstream, then across the placenta and through the umbilical cord to the fetus.
Do twins share a placenta during pregnancy?
Yes, twins can share a placenta during pregnancy. This occurs when identical twins develop from a single fertilized egg and share the same placenta.
Do fraternal twins share a placenta?
Yes, fraternal twins can share a placenta if they are from the same fertilized egg that split into two embryos.
Are twins in the same placenta genetically identical"?
No, twins in the same placenta are not genetically identical. While identical twins share the same DNA, they may have slight genetic differences due to mutations that occur after fertilization.
