vagina in dogs

A fibromuscular tubular tract leading from the uterus to the exterior of the body in female placental mammals and marsupials, or to the cloaca in female birds, monotremes, and some reptiles[WP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the vagina is

A fibromuscular tubular tract leading from the uterus to the exterior of the body in female placental mammals and marsupials, or to the cloaca in female birds, monotremes, and some reptiles[WP]. The atlas records it as a organ at the organ scale in the dog.

Where the vagina is

It sits within the reproductive system. Positioned deliberately as part of this species body plan.

What the vagina connects to

The atlas records 23 typed relationships for it, across 6 kinds of connection. part of internal female genitalia, organ and oviduct, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the vagina. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as distal oviductal region, distal portion of oviduct and vaginae. Searching any of those names reaches this page.
