As the foetus develops in womb placenta plays an important role give two functions of placenta?

The placenta plays a vital role in supporting the development of the fetus during pregnancy. Here are two important functions of the placenta:

1. Nutrient Exchange: The placenta acts as a barrier between the maternal and fetal circulatory systems, allowing the exchange of essential nutrients and waste products. Oxygen and nutrients from the mother's blood diffuse across the placenta and into the fetal bloodstream, while carbon dioxide and waste products from the fetus diffuse back into the maternal circulation.

2. Hormone Production: The placenta produces various hormones that are crucial for maintaining pregnancy and preparing the body for childbirth. These hormones include:

- Human chorionic gonadotropin (hCG): hCG is responsible for maintaining the corpus luteum, a small gland that forms on the ovary during ovulation and produces progesterone. Progesterone is essential for maintaining the uterine lining and supporting early pregnancy.

- Estrogen: Estrogen contributes to the growth and development of the uterus, breasts, and other reproductive organs in preparation for childbirth.

- Progesterone: Progesterone relaxes the uterine muscles and prevents premature contractions. It also helps to maintain the uterine lining and support the growth of the fetus.
