Fetal Development - implantation is the landmark for the first choking maneuver for a third-trimester pregnant 28-year-old

The process by which the embryo affixes to the uterine endometrial surface, invades the epithelium, and eventually enters the mother's bloodstream to develop into the placenta is known as implantation.

The sperm and egg combine during fertilization to generate a zygote in one of the fallopian tubes. The zygote then passes through the fallopian tube and develops into a morula. A blastocyst develops from the morula once it enters the uterus. The blastocyst subsequently undergoes implantation, where it burrows into the uterine lining.
