What is the placenta?

The placenta is an organ that develops during pregnancy in many animals, including humans. They are usually born in descendants, and therefore sometimes called birth. The function of the organ is to connect the mother's body to the fetus and allow a relatively safe interface between the two bodies. In humans, it is usually in the shape of a disk, reaches a length of about 9 inches (22 centimeters) and slightly less than the thumb in thickness and weighs approximately 1 pound (453 grams). In other animals, the size and exact shape of the organ may differ, but the function is almost the same.

One of the most important functions of this temporary organ is the transmission of nutrients and oxygen to the fetus. It is also responsible for deprivation of the waste produced by the fruit. It connects to the fetus through the umbilical cord and to the mother through the uterine wall, where it is firmly anchored. Nutrients, waste and gases are exchanged through the organ, but blood is never transmitted. Blood has never changed, so the fetus has added protection from some problems that are transmitted by the exchange of fluids. Some viruses as well as toxins from smoking or alcola, can cross the placental barrier, and therefore it is still important for mothers to delay dangerous activities and seek help when sick

In addition to the interconnection of the mother and the fetus, the human placenta serves several other features. It produces hormones, including estrogen, progesterone and beta of human chorionic gonadotrophin. The chemicals excreted by the organ can also help prevent the mother's body from attacking fetus and placenta, as if it were an attacker.

Unfortunately, this important organ is also a source of several problems in pregnancy. Some disorders are caused by placenta placing and may lead to bleeding. Others are the result of an early body separation, which can also cause bleeding. Problems can also be caused by placenta infection. All these problems are very serious and any pain, bleeding or other unusual symptoms should be immediately examined to prevent fetal damage orAbout mothers.

Placenta is a source of many rituals and traditions in human cultures. Some companies bury the placenta and others eat, but there are many other ways of ritually liquidating the body. It is known that many animals eat placenta, which are assumed that they contain valuable nutrients for the mother. Western medicine traditionally recommends burning the placenta after birth, but some people decide to communicate with the placenta rather than destroy it, often chose to eat or donate it for scientific research.
