The placenta is a very remarkable organ, and only a few women who've seen it. They know of its existence but only a small part of a collection notice asking or major support networks in the lives of babies in the womb.
The placenta consists of over 200 vessels and subtle veins,shaped like a lump of raw liver. Surface attached to the maternal womb, looked coarse and hollow. Deep red color and is divided into 15-20 bulge cotyledon, which is the villi or finger-shaped protrusions. Surface of the fetus is very soft, with the umbilical cord is usually found in the middle.
When the umbilical cord at the edge of the so-called battledore placenta. The placenta is fully grown, shaped like a flat disc. It weighs about 500 grams, diameter 20 cm (8 inches)thick, the middle 2.5 cm (1 inch). The size and weight adjusted to the size of the fetal placenta. The placenta is usually located at the top of the uterus, but when it is at the bottom, it is called Placenta Previa (Read: Placenta previa).
The placenta has four functions:
1. Function to sends nutrients and oxygen from maternal blood to the fetus.
2. Carrying carbon dioxide and disposal of fetal remains back to the mother's blood.
3. Forming of detention for infections and certain drugs. But the rubella virus and high-dose aspirin can penetrate the defenses of the placenta. Antibodies from the mother's blood can also cross the placenta and provides immunity to certain diseases shortly after childbirth.
4. Secrete hormones, particularly human chorionic gonadotrophin (HCG), progesterone and estrogen (See: The hormones of pregnancy).

Umbilical cord looks shiny and bluish in color, look inside the blood vessels are protected and supported. Large venous umbilical cord blood contains a charge of carrying nutrients and oxygen from the placenta, umbilical cord arteries and two veins that carry blood around that it was too deoxidation and the remnants of etus to the placenta.
All surrounded by a jelly-like material called Wharton jelly.Tali started twisting on its own navel, and at birth was about 40 circles. Are not uncommon when a baby's umbilical cord twist. The umbilical cord will remain rigid, due to blood flow in it. The average length of 50cm, although varying between 7.5 cm to 200cm. Thickness of about 12mm, but it is uneven due to the presence of small bumps called false knots. It may have with him no blood vessels or Wharton jelly blobs rising.
True knots can also occur due to movement of the fetus, but as long as no interest is too strong there will be no effect on the circulation. The umbilical cord is too short to complicate the birth of a baby, on the contrary, if too long to fall "into the genitals precedes the baby's head. A long rope wrapped around the body tend to the baby, but the danger will arise when the windings are too tight.
So head out, the baby's neck is generally checked to ensure that the umbilical cord is not convolute it. If it does, then it will be parsed through the umbilical cord is clamped and cut through its head. Although ultrasound is difficult to detect the umbilical cord, but the position of the placenta is more easily seen and if necessary do a cesarean section.
