The implantation of a zygote occurs in which part of the female body?

The female reproductive system comprises a pair of ovaries, a pair of fallopian tubes (oviducts), a uterus, and a vagina.

Once the embryo hatches out of the blastocyst, it embeds itself in the inner wall (endometrium) of the uterus which is highly vascular. This process is known as implantation.

Thus, the implantation of a zygote occurs in the uterus of the female reproductive tract.
