Why does oviduct open into the body cavity by a wide, funnel-shaped fimbriated ostium?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Oviduct Structure**: The oviduct, also known as the fallopian tube, has a specific structure that includes a wide, funnel-shaped opening called the fimbriated ostium.

2. **Function of the Oviduct**: The primary function of the oviduct is to transport the egg (ovum) from the ovary to the uterus. Each month, an egg is released from the ovary during ovulation.
