The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it.
The placenta in mammals is divided into two types, namely the yolk sac placenta and chorioallantoic placenta. The placenta is disk-shaped and measures up to 22 cm in length. The placenta is also rich in blood vessels. The placenta is formed by chorion and the uterine tissue.
Placenta is a disc like structure that forms a connection between the embryo and the uterine wall. It is consists of numerous villi that increases the surface area for absorption. It is an organ of exchange that provides oxygen and nutrients to fetus and removes waste produced by fetus.
