A. Placenta grade 3 refers to a classification system used to evaluate the maturity and function of the placenta during pregnancy. The placenta is a vital organ that supplies oxygen and nutrients to the developing fetus. The placenta grading system, also known as the Grannum classification, assesses the placenta's maturity based on ultrasound observations. Grade 3 indicates a more mature placenta, which is typically seen in the third trimester (after 28 weeks).
