What is the function of 'placenta'?

Question

Answer

The placenta is an organ which is responsible for now rising and protecting a fetus dwing pregnancy.

Two function of placenta are:

1 It allows gas exchange so that the fetus gets enough of oxygen and also helps it to get sufficient nuterition.

2 Placenta removes the waste from the fetus for processing by the mother's body, also helps in filteration of microbes that cold was infection.

Answer

1)Placenta allows the exchange of materials between mother and foetus.

2)It allows the transfer of nutrients and oxygen from mother to foetus.

3)Waste products excreted by the foetus like urea, uric acid and even carbon dioxide are diffused to maternal blood stream by the placenta.

4)Antibodies pass through the placenta that provides immunity to the foetus.

5)Placenta secretes several hormones that are essential for foetal development.

Answer

The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it.

Answer

The Function of the Placenta

The placenta is an essential organ that develops in the uterus during pregnancy. It plays a crucial role in supporting the growth and development of the fetus. The placenta serves as a vital link between the mother and the baby, facilitating the exchange of nutrients, oxygen, and waste products.

Nutrient and Oxygen Exchange
One of the primary functions of the placenta is to provide the developing fetus with essential nutrients and oxygen. The placenta has a rich network of blood vessels that allow the transfer of these substances from the mother's bloodstream to the fetus. Through a process called diffusion, oxygen and nutrients such as glucose are transported from the mother's blood to the fetal blood. This ensures that the baby receives the necessary nourishment for growth and development.

Waste Removal
In addition to nutrient and oxygen exchange, the placenta also plays a crucial role in removing waste products from the fetal bloodstream. As the fetus grows and metabolizes nutrients, waste products like carbon dioxide and urea accumulate. The placenta acts as a filter, allowing these waste products to pass from the fetal blood into the mother's bloodstream. The mother's body then eliminates these waste products through the kidneys and lungs.

Hormone Production
The placenta is responsible for producing several hormones that are essential for maintaining a healthy pregnancy. One of the most crucial hormones produced by the placenta is human chorionic gonadotropin (hCG). HCG helps to sustain the uterine lining, preventing menstruation and ensuring the pregnancy remains viable. The placenta also produces hormones such as progesterone and estrogen, which help regulate the maternal body's changes during pregnancy.

Immune Protection
The placenta acts as a barrier, protecting the developing fetus from potentially harmful substances. It prevents the passage of certain pathogens and toxins from the mother to the fetus, safeguarding the baby's health. However, it is important to note that some substances, such as alcohol and certain drugs, can still cross the placental barrier and harm the developing fetus.

Conclusion
In conclusion, the placenta is a vital organ that performs numerous functions to support the growth and development of the fetus during pregnancy. It facilitates the exchange of nutrients and oxygen while removing waste products from the fetal bloodstream. Additionally, the placenta produces hormones necessary for maintaining a healthy pregnancy and provides immune protection for the developing baby. The placenta plays a critical role in ensuring the well-being of both the mother and the fetus throughout pregnancy.
