C) fornix.
D) external os.
E) fimbra.

Answer 1

The internal os connects the uterine cavity to the cervical canal.

Step-by-step explanation:

The internal os connects the uterine cavity to the cervical canal.

The cervix is the lower end of the uterus that protrudes downward into the vagina. It is about 2.5 cm long and has a small canal that connects the uterine cavity with the lumen of the vagina. This canal allows semen to enter the uterus and facilitates the passage of a baby from the uterus to the vagina during birth.

The internal os is the opening at the inner end of the cervical canal that connects it to the uterine cavity.
