What is the function of the fallopian tubes in females?

Correct Answer: C

Rationale: The correct answer is C: Transport eggs from the ovary to the uterus. The fallopian tubes serve as a passageway for eggs released from the ovary to travel to the uterus for potential fertilization. This is a crucial function in the reproductive process. The other choices are incorrect because: A: The fallopian tubes do not transport sperm; they transport eggs. B: The production of eggs occurs in the ovaries, not in the fallopian tubes. D: Estrogen is primarily produced by the ovaries and other endocrine glands, not by the fallopian tubes.

Correct Answer: C

Rationale: The correct answer is C: Seminal vesicles. Seminal vesicles produce seminal fluid, which is a major component of semen. This fluid provides nutrients and protection for sperm, aiding in their motility and survival. The other choices are incorrect because: A: Epididymis - Stores and transports sperm, but does not produce seminal fluid. B: Prostate gland - Produces a milky fluid that helps nourish and protect sperm, but it is not the primary site for seminal fluid production. D: Testes - Produce sperm through spermatogenesis, but do not directly produce seminal fluid.

Correct Answer: B

Rationale: The correct answer is B. The primary function of the vagina is to facilitate sperm entry into the uterus during sexual intercourse for fertilization to occur. The vagina serves as the passageway for sperm to travel from the penis into the uterus where fertilization takes place. The other choices are incorrect for the following reasons: A: Support implantation - Implantation occurs in the uterus, not the vagina. C: Store eggs - Eggs are stored in the ovaries, not the vagina. D: Secrete estrogen - Estrogen is primarily produced by the ovaries, not the vagina.

Correct Answer: A

Rationale: The correct answer is A: LH (Luteinizing Hormone). LH surge triggers ovulation by stimulating the release of eggs from the ovary. It works in conjunction with FSH to facilitate follicle development. Estrogen supports the growth of the uterine lining, while progesterone maintains it post-ovulation. FSH is responsible for follicle development but isn't the primary hormone for egg release.

Correct Answer: B

Rationale: The correct answer is B: Progesterone. Progesterone is responsible for thickening the endometrial lining in preparation for pregnancy by promoting the growth of blood vessels and glands. It also helps maintain the uterine lining to support a fertilized egg. Estrogen (choice A) stimulates the growth of the endometrium but progesterone is crucial for thickening. FSH (choice C) and LH (choice D) are involved in the regulation of the menstrual cycle and ovulation, not specifically in thickening the endometrial lining.
