Briefly describe the events leading to the implantation of the blastocyst in the uterus, including how it is nourished
What will be an ideal response
The blastocyst floats freely in the uterine cavity for two to three days, during which time it is nourished by uterine secretions. Six to seven days after ovulation, implantation begins. The trophoblast determines the readiness of the endometrium for implantation. If the mucosa is prepared for implantation, the blastocyst becomes embedded high in the uterus.
