In which anatomical structure does the embryo normally implant during early pregnancy?
Solution
Correct Answer: Option B
- The embryo normally implants in the uterus during early pregnancy.
- After fertilization, which typically occurs in the fallopian tube, the zygote begins to divide and develop as it travels toward the uterus.
- Upon reaching the uterus, the embryo embeds itself into the endometrial lining, which is specially prepared to support pregnancy by becoming thickened and rich in blood vessels.
- This implantation in the uterus is crucial because it provides the necessary environment for the embryo's growth, including nutrients and oxygen through the maternal blood supply.
- Implantation outside the uterus, such as in the fallopian tube or ovary, leads to an ectopic pregnancy, which is a medical emergency.
- The vagina is not involved in implantation; it serves as the passageway for sperm entry and for childbirth.
Therefore, the correct site of embryo implantation is the uterus.
