Solution
- 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.
