*Ampulla – The longest region of the oviduct occupying more than half of its total length and also has the largest diameter. This is the site of fertilisation. It is distinguished by its many mucosal folds. The ampulla is joined to the isthmus via the Ampullary-Isthmus junction. This junction is important in the mare as it acts as a regulatory checkpoint allowing only fertilised ova to pass any further along the oviduct and into the uterus.

*Isthmus – The caudal end of the oviduct joined to the uterus. The Isthmus is thicker walled than the ampulla and smaller in diameter. Its folded mucosa forms a [[The Oviduct_-_functional reservoire_-_Anatomy_%26_Physiology|functional reservoire]] for sperm in the female tract.

==Function==
*A connecting tube structure between the uterus and ovary where fertilisation occurs.
*Provide regulation check points for unfertilised oocytes.
*The mucosal glands produce oviduct secretions integral for:
**Supporting unfertilised oocyte
**Supporting spermatozoa in the oviduct
**Development of the early embryo
