Which of the following correctly describes the usual pathway of sperm through the female reproductive tract?

The usual pathway of sperm through the female reproductive tract begins at the vagina, progresses through the cervix, enters the uterus, and finally reaches the fallopian tubes. This pathway is essential for fertilization, as sperm must navigate through these structures to reach an egg that may be present in the fallopian tube.

Starting from the vagina, sperm are deposited during intercourse and then travel through the cervix, which acts as a barrier that can open to allow sperm to enter the uterus. Once in the uterus, sperm can move towards the fallopian tubes, where fertilization typically takes place if an egg is present. This sequence is vital for successful reproduction, as each structure plays a specific role in facilitating the journey of the sperm to meet the egg. The other pathways outlined do not accurately follow the anatomical and physiological processes involved in fertilization, as they suggest incorrect sequences or include structures that sperm do not pass through in the specified order.
