Oviducts of the Female Dog

The oviducts (Either of a pair of tubes conducting the egg from the ovary to the uterus), also known as fallopian tubes, are very thin tubes of approximately 5 to 8 cm in length which are found in the ovarian bursa (A small fluid-filled sac located between movable parts of the body especially at joints) and which surround the ovaries. These oviducts are responsible for capturing the mature ovules when they become detached from the ovaries, preventing them from falling freely into the abdomen. In their internal part, the oviducts are covered by cilia (A hairlike projection from the surface of a cell; provides locomotion in free-swimming unicellular organisms) which with one rhythmic movement push the uterine horns towards the ovules and fluids produced by ovaries.
