What is placenta,? mention its role?

Question

Answer

A disc like special tissue developed between the utherus wall (called urine wall) and the embryo (or foetus) is called placenta...... The foetus is connected to the mother's body through the umbilical cord. It is through the placenta that all the requirements of the developing foetus like nutrition, respiration and excretion etc. are met from the mother's body. In the other words, the exchange of nutrients, oxygen and waste products b/w the embryo and the mother takes place through placenta.....

Answer

Placenta is disk like tissue which located between the embryo and uterus wall and the exchange for nutrients food between mother and embryo take place through placenta.

Placenta is the disc shaped tissue which developed between the uterus and embryo when embryo is implanted in the uterus. The main role of placenta is to provide nutition and oxygen to the embryo and remove the waste products from it.

Answer

The placenta is an organ found only in mammals during development of foetus. It is made up of cells derived from both mother and foetus.Placenta allows the exchange of materials between mother and foetus.It allows the transfer of nutrients and oxygen from mother to foetus.Waste products excreted by the foetus like urea, uric acid and even carbon dioxide are diffused to maternal blood stream by the placenta.Antibodies pass through the placenta that provides immunity to the foetus.Placenta secretes several hormones that are essential for foetal development.

Answer

What is Placenta?
The placenta is a vital organ that develops in the uterus during pregnancy. It forms a connection between the mother and the developing fetus, playing a crucial role in supporting fetal growth and development.
Role of the Placenta
The placenta serves multiple essential functions:

Nutrient Transfer: It facilitates the transfer of essential nutrients and oxygen from the mother’s bloodstream to the fetus, which is critical for growth and development.
Waste Elimination: The placenta helps in removing waste products such as carbon dioxide and urea from the fetal blood, ensuring a clean environment for the fetus.
Hormone Production: It produces hormones like human chorionic gonadotropin (hCG), progesterone, and estrogen, which are vital for maintaining pregnancy and preparing the mother’s body for childbirth.
Immune Protection: The placenta acts as a barrier to certain infections and provides some degree of immune protection to the fetus, transferring maternal antibodies.
Gas Exchange: It allows the exchange of oxygen and carbon dioxide between the mother and fetus, effectively acting as the lungs for the developing baby.

Conclusion
In summary, the placenta is an extraordinary organ that plays a multifaceted role in ensuring the health and well-being of both the mother and the fetus throughout pregnancy. Its functions are crucial for successful fetal development and the overall outcome of pregnancy.
