Step-by-step explanation:
The roots metr/o and hyster/o both pertain to the uterus. They are often used in medical terminology to refer to various conditions, procedures, or aspects of the uterus. The internal female reproductive structure, the uterus, is a pouch-like, muscular organ in which the embryo or fetus develops until birth, and it is crucial to the reproductive process.
The cervix, the lower part of the uterus, plays a significant role during fertilization and childbirth. It produces mucus that aids the movement of sperm through the reproductive tract during ovulation and dilates during childbirth to allow passage of the baby. Fertilization typically occurs in the fallopian tube, specifically in the distal section closest to the ovary, after sperm have entered through the vagina.
