Question: Explain how the uterus and placenta provide necessary conditions for proper growth and development of the embryo after implantation?
The correct answer is :
● The lining of the uterus thickens and is richly supplied with blood to
nourish the growing embryo.
● The embryo gets nutrition from the mother’s blood with the help of
placenta. It 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.
● The child is born as a result of rhythmic contractions of the muscles in the
uterus.
