35
Q

The internal genitalia include a
three-part system of ducts:

A

the uterine tubes, the uterus, and the vagina.

36
Q

The ovaries produce

A

egg cells and release them for
fertilization

37
Q

The ripe egg travels along the fallopian tube to the uterus, the____________ in which it develops into an embryo and
then fetus.

A

Muscular sac

38
