BIOLOGY
Asked by Jeniffer

Where is the umbilical cord located? Where is the uvula?

Uvula is soft is a small, and soft conical projection of soft palate; it hangs inside throat. Nasal passage ends behind uvula. Umbilical cord is a fetal structure which helps the mammalian baby to attach to placenta. Blood vessels remain embedded in gelatinous mass of the long cord. At pacenta, oxygen and carbon dioxode are exchanged between mother's blood and baby's blood. However, their blood will not ever come in direct contact. There are two arteries and one vein in umbilical cord. The arteries carry deoxygenated blood from fetus to placenta while oxygenated blood come back to fetal heart by the vein. There are no nerves in the cord: allowing that in the ‘after-birth’ the cord can be safely clamped and then removed by cutting.
