Question

In human beings, the implantation of fertilised egg takes place in which part of female reproductive system?

• A. Oviduct
• B. Cervix
• C. Uterus
• D. Vagina

Hint:

Fertilisation → Oviduct. Implantation → Uterus.

Answer 1

The Correct Option is C

Concept: Implantation is the process by which a fertilised egg (zygote) attaches itself to the wall of the female reproductive organ to begin development into an embryo. Explanation:

• Fertilisation occurs in the oviduct (fallopian tube).
• The fertilised egg divides repeatedly to form a multicellular structure called a blastocyst.
• This structure travels to the uterus.
• It gets embedded in the thick, vascular lining of the uterus (endometrium).

Why Other Options Are Incorrect:

• (A) Oviduct → Site of fertilisation, not implantation.
• (B) Cervix → Lower part of uterus, not implantation site.
• (D) Vagina → Passage for birth and intercourse.

Conclusion: Implantation of the fertilised egg takes place in the uterus, where it attaches to the uterine lining and develops into an embryo.
