What does embryo do before implantation?
Just prior to ovulation, the endometrium begins to thicken and to expand in response to the release of estrogen from the ovaries. As the embryo moves through the fallopian tubes, the endometrium proliferates, changes in shape, becomes receptive to implantation, and produces a hospitable environment for the embryo.
What is the first part of an embryo to develop?
Just four weeks after conception, the neural tube along your baby’s back is closing. The baby’s brain and spinal cord will develop from the neural tube. The heart and other organs also are starting to form and the heart begins to beat. Structures necessary to the formation of the eyes and ears develop.
What are the products of conception known as prior to implantation?

Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining — a process called implantation.
