What is the function of the umbilical cord in a pig?

Does the mother’s blood enter the fetus?

The mother’s blood does not normally mix with the baby’s blood during the pregnancy, unless there has been a procedure (such as amniocentesis or chorionic villus sampling) or vaginal bleeding. During delivery, however, there is a good chance that some of the baby’s blood cells will enter the mother’s bloodstream.

Does the diaphragm function in a fetal pig?

It is responsible for drawing air into the chest cavity. The fetal pig does not use the diaphragm because gas exchange occurs through the umbilical cord. The diaphragm in adult pigs moves up and down changing air pressure in the chest cavity causing air to move into and out of the lungs.

Which internal organ is the largest in the fetal pig?

liver
