Female
- Empties at the external urethral orifice
- Ventral wall of vagina
- At the vestibulo vaginal junction
- Only urine passes through it
- Length and diameter is species specific
- Short and wide - mare
- 2 fossa - bitch
- Sub urethral diverticulum - cow and sow
Male
- Empties at tip of penis
- Divided into 3 parts
- Pre-prostatic - bladder neck to seminal hillock
- Prostatic portion - openings of deferant, vesicular and prostatic ducts
- Penile portion - ischial arch to penile tip
- Note the first 2 combined are called the pelvic portion
Blood Supply
Blood Supply comes from the Urethral Artery
