The correct spelling for the blood vessel that connects the umbilicus to the fetus is "Vena Umbilicalis." It is pronounced /ˈviː.nə ʌmˈbɪ.lɪ.kəl.ɪs/ in IPA phonetic transcription. The first word, "vena", is pronounced as "VEE-nuh" and refers to a vein. The second word, "umbilicalis", is pronounced as "um-BIL-i-kal-is" and refers to the umbilicus or navel. This blood vessel is crucial for fetal development and is an important component of the umbilical cord, which connects the fetus to the placenta.
The term "Vena Umbilicalis" refers to a blood vessel within the human body that is commonly known as the umbilical vein. It is a major blood vessel that is responsible for carrying oxygenated blood and vital nutrients to the developing fetus during pregnancy. The vena umbilicalis is present in the umbilical cord, which connects the fetus to the placenta.
During fetal development, the vena umbilicalis arises from the placenta and extends towards the fetus, passing through the umbilical cord. This blood vessel carries oxygenated blood that is rich in nutrients from the mother to the fetus, providing essential nourishment for its growth and development.
Upon reaching the fetus, the vena umbilicalis delivers the oxygenated blood primarily to the liver. Inside the liver, the vessel splits into branches, supplying the organ with oxygen and nutrients. A portion of the oxygenated blood bypasses the liver, entering a specialized fetal blood vessel called the ductus venosus, which allows blood to bypass the liver and enter directly into the heart. From the heart, the oxygenated blood is then circulated throughout the fetal body.
After birth, the vena umbilicalis undergoes a series of natural changes. It typically begins to constrict and subsequently close, transforming into a fibrous cord known as the ligamentum teres hepatis or the round ligament of liver. However, remnants of the vena umbilicalis can persist in adults as a non-functional structure.
A vein in the fetus which is connected with the portal vein until birth when it is obliterated, becoming the ligamentum teres of the liver.

The term "Vena Umbilicalis" is of Latin origin. The word "vena" means "vein" in Latin, while "umbilicalis" refers to something related to the umbilicus, which is the medical term for the navel or belly button. Therefore, "Vena Umbilicalis" translates to "umbilical vein" in English. This term is commonly used in anatomy to refer to the vein that connects the placenta to the fetus during pregnancy.
