Reproductive System Exam Quizlet
1. Inevitable abortion occurs when:
- A. The ovum dies in utero and the decidua capsularis remains intact.
- B. The cervix is open, and the products of conception are about to be expelled.
- C. The products of conception are expelled before the 20th week of gestation.
- D. The fetus dies and is expelled in the first trimester.
Correct answer: B
Rationale: Inevitable abortion occurs when the cervix is open, and the products of conception are about to be expelled. This is a critical point in the process of spontaneous abortion, indicating that expulsion of the products of conception is imminent. Choice A is incorrect as it describes a missed abortion where the ovum dies but the decidua capsularis remains intact. Choice C is incorrect as it describes an incomplete abortion where the products of conception are expelled before the completion of 20 weeks of gestation. Choice D is incorrect as it describes a missed abortion where the fetus dies and is expelled in the first trimester.
2. Which hormone is released from the testes?
- A. Progesterone
- B. Vasopressin
- C. Testosterone
- D. None of the above
Correct answer: C
Rationale: The correct answer is testosterone. Testosterone is the primary male sex hormone produced in the testes. Progesterone is a female sex hormone primarily produced in the ovaries, not in the testes. Vasopressin is a hormone released by the pituitary gland to regulate water balance in the body, not produced by the testes. Therefore, choices A, B, and D are incorrect.
3. What is an organelle that helps the sperm to penetrate the ovum?
- A. Acrosome
- B. Zona pellucida
- C. Megalis
- D. None of the above
Correct answer: A
Rationale: The correct answer is Acrosome. The acrosome is an organelle located at the head of a sperm cell and contains enzymes that aid in the penetration of the ovum during fertilization. The Zona pellucida is a glycoprotein membrane surrounding the ovum, not an organelle. Megalis is not a relevant organelle in this context. Therefore, the correct choice is A, Acrosome.
4. What does reproductive health refer to?
- A. Healthy baby
- B. Frequent coitus
- C. Healthy reproductive organs and functions
- D. Longer lifetime
Correct answer: C
Rationale: Reproductive health refers to the overall well-being of the reproductive system, including both the organs and their functions. It encompasses the ability to have a satisfying and safe sex life, the capability to reproduce, and the absence of reproductive problems. Choice A is incorrect because reproductive health is not solely about having a healthy baby but also includes the health of the individual. Choice B is incorrect as it focuses only on sexual activity frequency rather than the holistic well-being of the reproductive system. Choice D is incorrect because a longer lifetime does not specifically relate to reproductive health.
5. During the menstrual cycle, which hormone maintains the corpus luteum?
- A. Luteinizing hormone
- B. Follicle-stimulating hormone
- C. Progesterone
- D. Relaxin
Correct answer: A
Rationale: During the menstrual cycle, luteinizing hormone maintains the corpus luteum. The correct answer is A. Luteinizing hormone stimulates the corpus luteum to produce progesterone. Choice B, Follicle-stimulating hormone, is involved in stimulating the growth of follicles in the ovaries. Choice C, Progesterone, is produced by the corpus luteum and plays a role in preparing the endometrium for implantation. Choice D, Relaxin, is involved in processes such as softening the cervix and ligaments during pregnancy, but it is not responsible for maintaining the corpus luteum.
