Verified step by step guidance

Understand the function of the placenta: The placenta is an organ that develops during pregnancy to facilitate the exchange of nutrients, oxygen, and waste products between the mother and the fetus. It also produces hormones essential for maintaining pregnancy.

Eliminate incorrect options: Review each statement critically. For example, the placenta is not present only during the first month of pregnancy—it remains throughout pregnancy. Additionally, the placenta does not produce sperm and eggs, as these are functions of the reproductive system.

Clarify the structure of the placenta: The placenta is formed from both maternal and fetal tissues, not entirely from maternal tissue. Specifically, it includes the maternal decidua and the fetal chorionic villi.

Identify the correct statement: The placenta's primary role is to allow for the exchange of nutrients and waste products between the mother and fetus, which is essential for fetal development.

Conclude with the correct understanding: The correct statement is that the placenta allows for the exchange of nutrients and waste products between mother and fetus, as this aligns with its biological function.
