Step 1: Ovulation.
During ovulation, the ovary releases a mature ovum (egg) into the peritoneal cavity.
Step 2: Structure responsible.
The funnel-shaped part of the fallopian tube, called the infundibulum, is responsible for collecting the ovum.
\[\begin{array}{rl} \bullet & \text{The margins of the infundibulum have finger-like projections called fimbriae.} \\ \bullet & \text{Fimbriae are close to the ovary and help in guiding the ovum into the fallopian tube.} \\ \end{array}\]
Step 3: Conclusion.
Thus, the infundibulum with fimbriae of the fallopian tube collects the ovum after ovulation.
