The diagram shows the different
parts of the female reproductive system. Which of the following statements
is incorrect? (A) Structure C is responsible for
secreting most of the sex hormones in the female reproductive system. (B) Structure E is responsible for
secreting most of the sex hormones in the female reproductive system. (C) Structure A has a lining whose
thickness changes over the course of the menstrual cycle.
The female reproductive system is
composed of many parts, some of which are labeled in the diagram. Let’s discuss the function of each
of these parts to determine which statement is incorrect.
Label E points to the ovary. This is the female gonad. There is one on each side of the
female reproductive system. The ovaries are where eggs and
female sex hormones, such as estrogen and progesterone, are produced.
Label C indicates the fallopian
tube. The fallopian tube is attached to
each ovary. Once an egg is released by the
ovary during ovulation, it passes through the fallopian tube, where fertilization
with a sperm cell can occur. The fertilized egg cell, or zygote,
can continue through the fallopian tube to the uterus. The uterus is indicated by both
labels A and B.
During the time in the fallopian
tube, the zygote can develop into an embryo and implant in the uterine lining to
create a pregnancy. This uterine lining thickens during
the course of the menstrual cycle to create an environment that’s appropriate for
embryo implantation. If an embryo doesn’t implant, then
the uterine lining sheds during menstruation.
Finally, label D indicates the
cervix. This is a length of tissue that
connects the vagina to the uterus.
Now that we’ve gone over the
provided diagram, we can answer our question. Remember, we are looking for an
incorrect statement regarding the female reproductive system. And this is given by answer choice
(A). Structure C is responsible for
secreting most of the sex hormones in the female reproductive system.
