Oviducts

Definition

Oviducts, also known as fallopian tubes, are the tubular structures that connect the ovaries to the uterus. They are crucial for the transport of ova and the site where fertilization typically occurs.

3. Fertilization usually takes place in the ampulla, a widened section of the oviduct.
4. Ectopic pregnancies can occur if a fertilized egg implants in an oviduct instead of traveling to the uterus.
