Question

What is placeta? Explain its structure and function in brief.

Answer 1

Placenta:-

• The embryo gets nutrition from the mother's blood with the help of a special tissue called placenta

• This is a disc which is embedded in the uterine wall.
• It contains villi on the embryo's side of the tissue.
• On the mother's side are blood spaces, which surround the villi.
• This provides a large surface area for glucose and oxygen to pass from the mother to the embryo.
• The developing embryo will also generate waste substances which can be removed by transferring  them into the mother's blood through the placenta.
