The deferent duct (vas deferens):

Correct Answer: C

Rationale: Step-by-step rationale for Choice C (Continues the epididymal duct) being the correct answer: 1. The deferent duct, also known as the vas deferens, is a continuation of the epididymal duct. 2. Sperm mature and are stored in the epididymis before passing into the vas deferens. 3. The vas deferens carries sperm from the epididymis to the ejaculatory duct during ejaculation. Summary: - Choice A is incorrect because the deferent duct does not join with the seminal vesicle duct to form the ejaculatory duct. - Choice B is incorrect as the vas deferens does not continue the rete testis. - Choice D is incorrect as the vas deferens is an intratesticular spermatic duct, not extratesticular.

Correct Answer: B

Rationale: The correct statement is B: it displays the glandular parenchyma on the inside. The ovary contains specialized tissue called parenchyma, which consists of follicles that house the ova (eggs). This glandular tissue is responsible for producing hormones like estrogen and progesterone. Rationale: - A is incorrect because the ovary is actually covered by a specialized epithelial layer called the germinal epithelium, not a simple epithelium. - C is incorrect because while the ovary does contain follicles at various stages of development, this alone does not encompass the entire function or structure of the ovary. - D is incorrect because the ovary is connected to the Fallopian tube via the infundibulopelvic ligament, not directly by ligaments.

Correct Answer: B

Rationale: The correct answer is B: uterus. The Fallopian tube connects the ovaries to the uterus, allowing eggs to travel from the ovaries to the uterus for fertilization. The vagina (A) is not directly connected to the Fallopian tube but serves as the birth canal. The ovary (C) is where eggs are produced and released into the Fallopian tube, not directly linked to it. The vulva (D) is the external part of the female genitalia and is not connected to the Fallopian tube.

Correct Answer: C

Rationale: The correct answer is C: the uterus. The uterine artery vascularizes the uterus, providing the main blood supply to this reproductive organ. This artery plays a crucial role in supplying oxygen and nutrients to the uterus, supporting the growth and development of the endometrium and the fetus during pregnancy. Choice A, the vagina, is incorrect because the vaginal artery, not the uterine artery, supplies blood to the vagina. Choice B, the Fallopian tubes, is incorrect as they are primarily vascularized by the tubal branches of the ovarian arteries. Choice D, the vulva, is also incorrect as the blood supply to the vulva comes from multiple sources including the internal pudendal artery and the external pudendal artery, not the uterine artery.

Correct Answer: A

Rationale: The correct answer is A because the primary function of the human male reproductive system is to produce gametes (sperm) in the testes. Sperm are essential for fertilization and reproduction. Choice B is incorrect as the fluid that protects the fetus is produced by the female reproductive system. Choice C is incorrect as embryo development support is provided by the female reproductive system. Choice D is incorrect as the placenta, which provides nutrient materials, is a structure formed by the female reproductive system during pregnancy.
