This is the connection between the bladder and the external environment.

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
