Answer #1

The usual site of fertilization is the

Answer: C) Oviduct

Explanation:

- The ampulla of the oviduct (fallopian tube) is the most common site for fertilization. Fertilization is the process of fusion of male gamete (sperm) and female gamete (oocyte) to form zygote.

- The fimbriae of the oviduct collects the released oocyte during ovulation from the ovary. The oocyte is transported along the oviduct due to the ciliary movement of the lining of oviduct as well as the smooth muscle contraction of oviduct. Once the oocyte reaches the ampulla of the oviduct, it meets the sperm and fertilization takes place.

- The zygote formed during fertilization in the ampulla of oviduct divides and once the blastocyst stage of the embryo is formed, it is implanted into the uterine endometrium around day 6th post fertilization.
