What does an 'ageing placenta' or 'calcification of the placenta' mean?
However, whether these microbes exist or are clinically important is highly controversial and is the subject of active research. The placenta intermediates the transfer of nutrients between mother and fetus. The perfusion of the intervillous spaces of the placenta with maternal blood allows the transfer of nutrients and oxygen from the mother to the fetus and the transfer of waste products and carbon dioxide back from the fetus to the maternal blood.
Nutrient transfer to the fetus can occur via both active and passive transport. Waste products excreted from the fetus such as ureauric aci and creatinine are transferred to the maternal blood by diffusion across the placenta. IgG antibodies can pass through the human placenta, thereby providing protection to the fetus in utero.
IgMhowever, cannot cross the placenta, which is why some infections acquired during pregnancy can be hazardous for the fetus. Furthermore, the placenta functions as a selective maternal-fetal barrier against transmission of microbes. However, insufficiency in this function may still cause mother-to-child transmission of infectious diseases.
The placenta and fetus may be regarded as a foreign body inside the mother and must be protected from the normal immune response of the mother that would cause it to be rejected. The placenta and fetus are thus treated as sites of immune privilegewith immune tolerance. However, the Placental barrier is not the sole means to evade the immune system, as foreign fetal cells also persist in the maternal circulation, on the other side of the placental barrier.
The placenta also provides a reservoir of blood for the fetus, delivering blood to it in case of hypotension and vice versa, comparable to a capacitor. The placenta often plays an important role in various cultureswith many societies conducting rituals regarding its disposal. In the Western worl the placenta is most often incinerated.
Some cultures bury the placenta for various reasons. The placenta is believed by some communities to have power over the lives of the baby or its parents. The Kwakiutl of British Columbia bury girls' placentas to give the girl skill in digging clams, and expose boys' placentas to ravens to encourage future prophetic visions.

Placental calcification is the medical term for some of the changes that happen to the placenta, as pregnancy progresses. Many researchers regard placental calcification as a normal ageing process, rather than a change related to a disease or ailment. The placenta is usually described as going through four grades, from 0. The placenta is a temporary organ that connects the developing fetus via the umbilical cord to the uterine wall to allow nutrient uptake, thermo-regulation, waste elimination, and gas exchange via the mother's blood supply; to fight against internal infection; and to produce hormones which support pregnancy. Placentas are a defining characteristic of placental mammals, but are also found in MeSH: D
In Turkeythe proper disposal of the placenta and umbilical cord is believed to promote devoutness in the child later in life. In Transylvaniaand Japaninteraction with a disposed placenta is thought to influence the parents' future fertility. Several cultures believe the placenta to be or have been alive, often a relative of the baby.
Nepalese think of the placenta as a friend of the baby; Malaysian Orang Asli regard it as the baby's older sibling. In some cultures, the placenta is eaten, a practice known as placentophagy.

Nov 01, It is widely believed that during the relatively short duration of a normal pregnancy the placenta progressively ages and is, at term, on the verge of a decline into morphological and physiological senescence This belief is based on the apparent convergence of clinical, structural, and functional data, all of which have been taken, rather uncritically, as supporting this concept of the Cited by:

Still, I was so freaked out about the possibility of awful things happening to me that I started taking the placenta pills as a sort of insurance policy. I declined all pain medication stronger than ibuprofen, and I even stopped using deodorant, fearing the rumors were true that aluminum might seep into my breast milk. I was a cheerful and healthy new mother.
Somehow, it seemed like a good idea at the time. But in my case, it was a terrible idea. Shortly after my first dose of two pills, I felt jittery and weird. By the next day, after just eight placenta pills, I was in tabloid-worthy meltdown mode, a frightening phase filled with tears and rage.
After I went cold turkey on the placenta pills, I immediately felt better -exorcised even, of an entity that had willingly left my body but that I had stupidly, and with no medical supervision, scarfed back up. Motherhood returned to being marvelous, save sleep deprivation.
