Which hormone is responsible for the development of the female reproductive system during puberty?

Correct Answer: A

Rationale: Estrogen is the correct answer because it is the primary hormone responsible for the development of the female reproductive system during puberty. Estrogen triggers the development of secondary sexual characteristics, regulates the menstrual cycle, and promotes the growth of the uterus and breasts. Testosterone is the male sex hormone and is not responsible for female reproductive system development. Progesterone's main role is in preparing the uterus for pregnancy and maintaining pregnancy, not in the initial development of the female reproductive system. FSH (Follicle-Stimulating Hormone) plays a role in regulating the menstrual cycle and stimulating the ovaries, but it is not the primary hormone responsible for the development of the female reproductive system during puberty.

Correct Answer: D

Rationale: The correct answer is D: LH (Luteinizing Hormone). LH surge triggers the release of the egg during ovulation. It stimulates the follicle to rupture and release the mature egg. FSH stimulates follicle development, estrogen prepares the body for ovulation, and progesterone maintains the uterine lining post-ovulation. LH is the hormone directly responsible for the release of the egg, making it the correct choice.

Correct Answer: C

Rationale: The correct answer is C: Epididymis. The epididymis is responsible for storing and maturing sperm. Sperm are produced in the testes and then travel to the epididymis for storage and maturation. The other choices, A: Seminal vesicles, B: Prostate gland, and D: Vas deferens, are not directly involved in storing and maturing sperm. Seminal vesicles and prostate gland produce fluids that nourish and protect sperm, while vas deferens is responsible for transporting sperm from the epididymis to the urethra during ejaculation.

Correct Answer: B

Rationale: The correct answer is B: Maintain the endometrium. Progesterone plays a crucial role in pregnancy by maintaining the endometrium, which is essential for the implantation and nourishment of the fertilized egg. Progesterone helps to thicken the endometrial lining, ensuring a suitable environment for implantation and supporting the developing fetus. Promoting ovulation (A) is primarily controlled by estrogen. Stimulating labor (C) is mainly regulated by oxytocin. Supporting lactation (D) is primarily influenced by the hormone prolactin. Therefore, the primary role of progesterone in pregnancy is to maintain the endometrium for the successful development of the pregnancy.

Correct Answer: B

Rationale: The correct answer is B: Uterus. After fertilization, the fertilized egg travels from the fallopian tube to the uterus for implantation. The uterus provides a suitable environment for the development of the embryo. The other choices are incorrect because: A: Ovary - Ovaries produce eggs but do not have a direct role in the implantation of the fertilized egg. C: Fallopian tube - While fertilization occurs in the fallopian tube, implantation takes place in the uterus. D: Cervix - The cervix is the lower part of the uterus that connects to the vagina and plays a role in facilitating sperm entry into the uterus, not in implantation.
