Question

Which structure is formed in the wall of the uterus to provide nutrition to the foetus?
A. Amnion
B. Fallopian Tube
C. Umbilical cord
D. Placenta

Answer 1

Hint: The uterus, also called the womb, is an inverted, pear-shaped muscular organ situated between the bladder and the rectum in the female reproductive system. It acts to nourish and hold a fertilised egg until the embryo or offspring is ready for delivery.

Complete Answer:
A crucial linking organ between the maternal foetus and the foetus is the placenta. It facilitates the production of the foetus in utero via the supply of nutrients, the removal of waste products from the foetus and the exchange of gas through the supply of maternal blood. It binds the developing embryo to the mother's cells and delivers it via the mother's blood with nutrients and oxygen and extracts the waste content from the embryo.

The amnion is a membrane which, when first developed, closely covers the embryo. It fills with the amniotic fluid that allows the amnion to extend and become the amniotic sac that is used to provide the developing embryo or foetus with a protective environment.

The Fallopian tubes are tubes that extend from the uterus to the ovaries and are part of the female reproductive system, also called uterine tubes or salpinges (singular salpinx). From the ovaries in female mammals to the uterus, the fertilised egg travels into the Fallopian tubes.

The umbilical cord is a tube that during birth, binds you to your infant. It has three blood vessels. One vein helps to bring food and oxygen to your baby from the placenta. Other two arteries help to bring waste back to the placenta from your baby.

So the correct option is D, placenta.

Note: Women are born without a uterus in some rare cases, which is called Mayer-Rokitansky Küster-Hauser syndrome. There is another very unusual disorder called uterus didelphys, where females are born with two uteruses.
