What is a function of placenta ?

Question

Answer

The placenta serves as an interface between the mother and the developing fetus and has three main jobs: Attach the fetus to the uterine wall. Provide nutrients to the fetus. Allow the fetus to transfer waste products to the mother's blood.

Answer

Here is your 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
__
The placenta acts to provide oxygen and nutrients to the fetus, whilst removing carbon dioxide and other waste products. It metabolises a number of substances and can release metabolic products into maternal and/or fetal circulations

Answer

Functions of the Placenta
The placenta is a vital organ that forms during pregnancy, providing essential support for fetal development. Here are its primary functions:
Nutrient Transfer
- The placenta facilitates the transfer of nutrients from the mother’s bloodstream to the fetus.
- Essential substances such as glucose, amino acids, and fatty acids are delivered to support fetal growth.
Gas Exchange
- This organ allows for the exchange of oxygen and carbon dioxide between the mother and fetus.
- Oxygen is supplied to the fetus while carbon dioxide produced by the fetus is removed, ensuring proper respiratory function.
Waste Elimination
- The placenta aids in the removal of metabolic wastes from the fetus.
- Waste products like urea and creatinine are transferred back to the mother’s circulation for excretion.
Hormone Production
- The placenta produces hormones critical for maintaining pregnancy, such as human chorionic gonadotropin (hCG), progesterone, and estrogen.
- These hormones play roles in supporting fetal development and preparing the mother’s body for childbirth.
Immune Protection
- Acting as a barrier, the placenta protects the fetus from certain infections.
- It also allows the transfer of antibodies from the mother to the fetus, providing some immunity.
Fluid Regulation
- The placenta helps regulate the amount of amniotic fluid, which is crucial for cushioning the fetus and allowing for movement.
- It maintains the right environment for fetal development.
The placenta is, therefore, an essential organ that supports the fetus in multiple ways, ensuring a healthy pregnancy.
