The two oval-shaped organs that produce, store, and release human eggs are called __________________.

Correct Answer: B

Rationale: The correct answer is B: ovaries. Ovaries are the organs responsible for producing, storing, and releasing human eggs. They are oval-shaped and play a crucial role in the female reproductive system. The other choices are incorrect because: A: clitoris is a small, sensitive organ located near the entrance of the vagina, not involved in egg production. C: Fallopian tubes are responsible for transporting eggs from the ovaries to the uterus, not for producing or storing eggs. D: Vagina is the muscular tube connecting the uterus to the outside of the body, not involved in egg production.

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: A

Rationale: The correct answer is A: head. The spermatozoon is composed of three main parts: head, mid piece or neck, and flagellum. The head contains the nucleus which carries genetic material. The mid piece or neck contains mitochondria for energy production. The flagellum is responsible for sperm motility. In this question, the head is the most essential part of the spermatozoon as it contains the genetic material required for fertilization. The other choices (B: mid piece or neck, C: flagellum, D: body) are incorrect as they are important for sperm function but do not carry the genetic material necessary for fertilization.

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.
