Answer 1

Answer:

The placenta connects the developing fetus to the wall of the mother's uterus during pregnancy. It grows in the wall of the uterus and is attached to the fetus within the uterine cavity by the umbilical cord.Together, the ICM and the trophoblast are called the blastocyst. A blastocyst successfully implants in the uterus when, as the ZP exits the fallopian tube, the blastocyst leaves the ZP and binds to the endometrium. ... Furthermore, the endometrium swells as interstitial fluid accumulates in it.Six to 10 days after fertilization, the embryo attaches, or implants, itself into the lining of the uterus. During the next week or so, the embryo receives its nourishment and oxygen from the cells that make up the lining of the uterus. The two layers of cells become more pronounced.

placenta

Explanation:

Implantation is a process in which a developing embryo, moving as a blastocyst through a uterus, makes contact with the uterine wall and remains attached to it until birth.
