Afterbirth

The placenta is the organ that connects the fetus with the mother's body. It consists of many vessels that ensure the exchange of substances between mother and fetus. The placenta plays an important role in the development of the fetus, providing it with nutrition and protection from harmful factors.

The placenta forms during pregnancy and begins to function at approximately 10-12 weeks. It is formed from the wall of the mother's uterus and attaches to the wall of the placenta. The placenta consists of three main layers: the basal layer, the intermediate layer and the villous layer.

The basal layer consists of cells that form the basis of the placenta. The intermediate layer consists of many blood vessels that connect the placenta to the maternal body. The villous layer consists of small villi that increase the area of ​​the placenta and ensure more efficient metabolism.

The umbilical cord is another important organ connecting the fetus and the mother's body. It is a cord that connects the fetus to the placenta. The umbilical cord consists of two arteries and one vein that carry oxygen and nutrients from the mother to the fetus and remove carbon dioxide and waste products from the fetus to the mother.

The amniotic membranes are the third important organ that connects the fetus with the mother's body. They consist of several layers that protect the fetus from external influences and ensure its normal functioning. The amniotic membranes also contain many blood vessels and nerve endings that provide communication between the fetus and the mother's body.

All these organs play an important role in the life of the fetus and mother. The placenta provides nutrition and protection to the fetus, the umbilical cord provides metabolism between the fetus and the mother, and the membranes provide support and protection to the fetus. All these organs work together to ensure the normal functioning of the fetus and the health of the mother.

The afterbirth is an organ that connects the fetus with the maternal body and provides nutrition and respiration. It consists of three main elements: the placenta, the fetal membranes and the umbilical cord itself, consisting of umbilical vessels. The afterbirth is a complex anatomical structure, therefore we will consider its anatomical structure and physiological function in more detail.

The placenta is a special formation that appears after the 16th week of pregnancy. The placenta consists of chorionic villi, which penetrate the maternal endometrium - the basal layer of the uterine mucosa - and form a complex three-layer organ.
