Which hormone is associated with increased basal metabolism and placenta growth during pregnancy?

  1. FSH

  2. Estrogen

  3. GH

  4. Progesterone

The correct answer is: Progesterone

The hormone that is associated with increased basal metabolism and placenta growth during pregnancy is estrogen. This hormone plays a crucial role in various physiological changes that prepare a woman's body for pregnancy and support fetal development. During pregnancy, estrogen levels rise significantly, leading to metabolic changes that enhance energy availability and maternal tissue growth. One of estrogen's primary functions includes stimulating the growth of the placenta, which is essential for providing nutrients and oxygen to the developing fetus. Additionally, estrogen helps regulate other hormones and prepares the mother’s body for childbirth. In summary, estrogen is integral to the metabolic adjustments that occur during pregnancy and plays a vital role in the growth and development of the placenta, ensuring a healthy environment for the fetus.
