Reproductive System Anatomy Quizlet Questions
Question 1 of 5
Failure of the ductus arteriosus to close is a common developmental defect. Which of the following would likely be present in a 12-month-old infant with patent ductus arteriosus?
Correct Answer: A
Rationale: The correct answer is A: Below-normal arterial PO2. In a 12-month-old infant with patent ductus arteriosus, there would likely be a left-to-right shunt causing increased blood flow to the lungs, leading to decreased systemic blood flow. This can result in decreased systemic oxygenation and below-normal arterial PO2 levels. Choices B, C, and D are incorrect because patent ductus arteriosus does not directly affect arterial PCO2, arterial blood pressure, or pulmonary arterial pressure in a way that would lead to those specific outcomes at this age.
Question 2 of 5
Where are sperm produced within a male's testis?
Correct Answer: A
Rationale: The correct answer is A: Seminiferous tubules. Sperm production occurs in the seminiferous tubules of the testis through a process called spermatogenesis. This is where germ cells develop into mature spermatozoa. The other choices are incorrect: B: Ejaculatory duct is where sperm and seminal fluid mix before ejaculation, C: Interstitial cells produce testosterone, and D: Rete testis is a network of tubules where sperm travel after being produced in the seminiferous tubules.
Question 3 of 5
The process by which a secondary oocyte is ejected from the ovary is called ________.
Correct Answer: D
Rationale: The correct answer is D: ovulation. This process involves the release of a mature egg (secondary oocyte) from the ovarian follicle. During ovulation, the egg is released into the fallopian tube, where it can potentially be fertilized by sperm. A: emission - Incorrect. This term typically refers to the discharge of semen from the male reproductive system. B: menses - Incorrect. Menses refers to the shedding of the uterine lining during menstruation, not the release of an egg from the ovary. C: fertilization - Incorrect. Fertilization is the process of the sperm uniting with the egg, which occurs in the fallopian tube after ovulation.
Question 4 of 5
Human chorionic gonadotropin (hCG) produces fluid that activates sperm.
Correct Answer: D
Rationale: The correct answer is D: corpus luteum. Human chorionic gonadotropin (hCG) is produced by the developing placenta during pregnancy. This hormone helps maintain the corpus luteum, which in turn produces progesterone to support the pregnancy. The fluid produced by the corpus luteum helps activate sperm for fertilization. Choices A, B, and C are incorrect as they are not directly involved in the production of hCG or the activation of sperm.
Question 5 of 5
The hormone that promotes a small protrudes into the vagina is the number of primary follicles within the ________. ovary to grow and mature each month
Correct Answer: D
Rationale: The correct answer is D: hymen. The hormone that promotes the growth and maturation of primary follicles in the ovary each month is follicle-stimulating hormone (FSH), not luteinizing hormone (LH) as mentioned in choice C. Choices A and B are anatomical structures not related to follicular development. The hymen is a thin membrane at the vaginal opening and has no direct role in promoting follicle growth. However, it is the most related choice as it is the only one that is a part of the female reproductive system.
