The correct option is D Cervical canal, vagina
Anatomically, the subdivisions of the uterus include: the uterine fundus, body of the uterus and lower cylindrical portion which opens into the vagina known as the cervix.
The interior cavity of the cervix is called the cervical canal. The cervical canal communicates with the body of the uterus through an opening called internal os while it communicates with vagina through an opening called external os.
Thus, the cervical canal is the cavity of the cervix and along with vagina forms the birth canal. The birth canal is a passageway for childbirth.
Fallopian tubes (oviducts) are female accessory ducts in which the fertilisation occurs.
Urethra is a thin tube that begins from the urinary bladder. In males, it serves as a common passage for both semen and urine.
