Placenta as a source of nutrition for the foetus:

The placenta is a specialized organ that develops in the uterus during pregnancy. It serves as a connection between the mother and the developing embryo (foetus) and plays a crucial role in providing nutrition and oxygen to the growing foetus.

The placenta is formed from both maternal and foetal tissues and is attached to the uterine wall. It is through the placenta that the foetus receives nutrients, oxygen, and other essential substances from the mother's bloodstream.

Functions of the placenta:

1. Nutrient and oxygen exchange: The placenta facilitates the exchange of nutrients, oxygen, and other essential substances between the mother's bloodstream and the foetus. The exchange occurs through a network of blood vessels in the placenta, which allow nutrients and oxygen to pass from the mother's bloodstream to the foetus' bloodstream.

2. Waste removal: The placenta also helps in removing waste products such as carbon dioxide and urea from the foetus. These waste products are then eliminated from the mother's body through her own excretory system.

3. Hormone production: The placenta produces hormones such as human chorionic gonadotropin (hCG), estrogen, and progesterone, which help maintain the pregnancy and support the growth and development of the foetus.

In conclusion, the placenta is the primary source of nutrition for the growing foetus during pregnancy. It facilitates the exchange of nutrients, oxygen, and other essential substances between the mother's bloodstream and the foetus' bloodstream, thereby ensuring the healthy growth and development of the foetus.

The embryo gets nourishment inside the mother body through a special tissue called placenta. The embryo grows inside the mother's womb and gets nourishment from mother's blood through the tissue called placenta. The placenta is a temporary organ that develops in the uterus during pregnancy. It attaches the fetus to the uterine wall. It also provides nutrients to the fetus and also allows the fetus to transfer waste product's to the mother's blood.
