The placenta  serves as a conduit for the return of waste products back to the mother for disposal.

What is the placenta?

An organ that grows in the uterus during pregnancy is the placenta. A developing newborn receives oxygen and nutrients from this structure. It also cleans the baby's blood of waste materials. The baby's umbilical cord grows from the placenta, which is attached to the uterus' wall throughout pregnancy. Typically, the organ is affixed to the uterus's front, rear, side, or top. Rarely, the placenta may connect in the uterine cavity below. This situation is known as a low-lying placenta.

The placenta has the following functions:

  • gives nutrition and oxygen to child.
  • takes carbon dioxide and toxic waste away from  child.
  • produces hormones that aid in the growth of child.
  • provides your baby with  immunity.
  • protects child
