Role of Placenta In Pregnancy

The placenta is the organ software. The placenta is round or oval. The placenta grows along with baby. In the 10th week of pregnancy, placental weight about 12 grams, until the baby is born, weighing up to 700 grams.

In early pregnancy, the placenta grows and sends blood vessels into the uterus. Blood vessels are moving food and oxygen from the pregnant woman’s body for use by infants. Waste products from the baby will go back into the flow of blood through the vessels to be disposed of by the pregnant woman’s body.

The placenta is thought to act as a barrier (barrier) of all substances outside the body. However, in some circumstances, the placenta can not keep the baby against substances that are used by the mother during pregnancy. drugs, other substances (such as nicotine), and various vitamins and minerals can cross the placenta and enter the baby’s body. That’s what causes pregnant women are warned to avoid the use of foreign substances during pregnancy.

The placenta is not just an organ to transport food is simple, but the placenta was also able to select food substances that enter and the other to the fetus. Supply of nutrients to the growing fetus depends on the amount of the mother’s blood flowing through the placenta and the nutrients that load. The efficiency of the placenta in the concentrate, synthesize, and transport of nutrients will determine the food supply to the fetus.

The fetus is experiencing malnutrition in general, due to the disruption of food supply from the mother, for example: placental vascular abnormalities resulting in reduced transport of nutrients through the placenta.

The placenta is very important for pregnancy and will remain important until the birth of the baby. In time, when the uterus shrink after the baby is born, the placenta will detach from the uterus and out by itself.
