Placenta
Placenta refers to the temporary vascular organ found in mammals, which attaches the fetus to the uterus of the mother during pregnancy. The placenta is exclusive to mammals.
- The umbilical cord connects the fetus to the placenta, facilitating the transfer of materials.
- The placenta is usually attached at the top, bottom, side, front or back of the uterus.
- In extreme cases, the placenta gets attached to the lower part of the uterus resulting in a condition known as placenta previa.
