NEET BIOLOGY

Detailed explanation-1: -The egg takes several days to travel down the fallopian tube into the uterus. After it is in the uterus, a fertilized egg usually attaches to (implants in) the lining of the uterus (endometrium).

Detailed explanation-2: -Implantation begins with apposition of the blastocyst at the uterine epithelium, generally about 2-4 days after the morula enters the uterine cavity. The implantation site in the human uterus is usually in the upper and posterior wall in the midsagittal plane.

Detailed explanation-3: -When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat). The zygote goes through a process of becoming an embryo and developing into a fetus.

Detailed explanation-4: -After conception, a fertilized egg travels through your fallopian tubes to your uterus. The fertilized egg (called an embryo) implants (attaches) into the wall of your uterus. This triggers the placenta to form. Your placenta begins producing and releasing human chorionic gonadotropin (hCG) into your blood and pee.
