What is the normal appearance of the placenta at term?

The normal appearance of the placenta at term is characterized as a flat circular disc, typically measuring around 2 to 3 cm in thickness. This thickness allows for optimal nutrient and gas exchange between the mother and fetus, supporting the developing baby's needs. At this stage, the placenta is well-developed, and its disc shape enables a larger surface area for these vital functions.

The thickness range of 2 to 3 cm is considered healthy, as it reflects the placenta's fully functioning state at term, where it supplies adequate blood flow and nutrients while removing waste products from the fetal circulation. This well-defined structure is essential for a successful pregnancy outcome, ensuring the fetus receives everything it requires for proper growth and development. Other thickness or shapes noted in the options like 1 to 2 cm, bulbous, or irregular configurations do not align with the established norms for a healthy term placenta.
