Question

Oviduct funnel has its significance of _______.
A. Released ovum from Graafian bodies
B. Makes a necessary change in endometrium for implantation
C. Helps in formation of corpus luteum
D. After ovulation it helps ovum to enter into the fallopian tube

Answer 1

Hint: Oviduct funnel is used to transport the ovaries from the ovaries to the uterus; they are also used for sperm fertilization of the ovum. With these structures, the finger-like projections are linked. The ovary is not connected to the fallopian tube directly.

Complete answer: In the female reproductive tract, the fallopian tubes are primary structures that connect the peritoneal cavity and the uterine cavity. The Fallopian tubes are two tubes that extend from the uterus to the ovaries. There are three sections of the fallopian tube: the isthmus (narrow) that connects to the uterus, the bulb (wider) in the middle, and the infundibulum with fimbriae that transport the ovum. Every month, one of the ovaries releases an egg that goes to one of the fallopian tubes throughout the ovulation phase, where sperm can or may not be fertilized. As ovulation is about to occur, sex hormones trigger the fimbriae (finger-like projections of the fallopian tubes), allowing them to fill with blood and slowly reach the ovary. Each oviduct (fallopian tube) forms like a funnel known as infundibulum in the female reproductive system. It consists of structures called fimbriae, finger-like, which travel on the ovary. The infundibulum guides the ovum through the fallopian tube when the ovum is being released from the ovary, where fertilization occurs.
Hence, the correct answer is option D.

Note: The main purpose of the uterine tubes is to help move the egg from the ovary to the uterus. In order to prevent eggs from moving from the fallopian tubes into the uterus, women who no longer want children can have their tubes attached. This procedure is called a tubectomy. Because of the peristaltic motions of the fallopian tubes, sperm transportation occurs.
