Placenta maturity level 1 at 32 weeks of pregnancy is normal. With the increase of pregnancy cycle, the placenta also gradually mature, according to the overall condition of the placenta can be divided into 4 levels: 1, level 0: generally refers to the placenta of 12-28 weeks of pregnancy, in immature state; 2, level 1: generally refers to the placenta of 30-32 weeks of pregnancy, at this time the placenta has been basically mature, can provide sufficient nutrition for the fetus. From this time, the fetus grows significantly faster and the placental maturation speed will be accelerated; 3.Grade 2: generally refers to the placenta after 36 weeks of pregnancy, the placenta is more mature; 4.Grade 3: generally refers to the placenta after 38 weeks of pregnancy, the placenta is mature and tends to age at this time. Due to calcification and fibrin deposition, the ability of the placenta to transport oxygen and nutrients is reduced, which will affect the growth and development of the fetus and make the fetus prone to intrauterine hypoxia. The maturity of the placenta is one of the criteria to measure whether the fetus is developing. Pregnant women at 32 weeks of pregnancy have entered the late stage of pregnancy, they should maintain a good living condition, adhere to appropriate exercise every day, increase nutrition, pay attention to fetal movement in real time, and have regular maternity checkups to ensure the healthy development of the fetus.
