Question 1 of 5

Which of these is not produced by the placenta?

Correct Answer: B

Rationale: The correct answer is B: relaxin. The placenta produces estrogen, progesterone, and lactogen to support pregnancy. Relaxin is primarily produced by the corpus luteum and later by the placenta. However, it is not exclusively produced by the placenta, making it the correct choice. Estrogen is crucial for fetal development and maintaining pregnancy. Progesterone helps in preparing the uterus for implantation and supporting the pregnancy. Lactogen (human placental lactogen) plays a role in regulating maternal metabolism and fetal growth.

Question 2 of 5

Which ligament arises from the pubic symphysis in males?

Correct Answer: C

Rationale: The correct answer is C: Suspensory ligament. This ligament arises from the pubic symphysis in males and supports the male reproductive organs. It helps suspend the penis and testes in the scrotum. The Fundiform ligament (A) supports the penis, the Broad ligament (B) supports the uterus, and the Ejaculatory ligament (D) is not a ligament associated with the pubic symphysis in males.

Question 3 of 5

What is line “F” pointing to?

Correct Answer: A

Rationale: The correct answer is A: Ductus epididymis. Line "F" is pointing to the ductus epididymis, which is a part of the male reproductive system where sperm mature and are stored. The ductus epididymis is located at the top of the testis and is connected to the rete testis. It is responsible for transporting sperm from the testis to the vas deferens. Explanation for incorrect choices: B: Rete testis - The rete testis is a network of tubules located within the testis, not the ductus epididymis. C: Efferent duct - Efferent ducts are small ducts that connect the rete testis to the epididymis, not the ductus epididymis itself. D: Afferent duct - Afferent ducts are responsible for transporting sperm from the rete testis to the epididymis, not within the epid

Question 4 of 5

Which of the following is not a contribution of the reproductive system to the body systems?

Correct Answer: C

Rationale: The correct answer is C: Increasing the rate and depth of breathing during sexual arousal. The reproductive system does not directly contribute to the rate and depth of breathing. The main function of the reproductive system is to produce and deliver gametes for reproduction. It does not have a direct role in regulating respiratory functions. Choices A, B, and D are incorrect because the reproductive system does contribute to maintaining bone health, regulating cholesterol levels in males, and stimulating muscle growth in males. These functions are known contributions of the reproductive system to the body systems.

Question 5 of 5

Uterine tubes are otherwise called as

Correct Answer: C

Rationale: The correct answer is C: Fallopian tubes. These tubes are also known as uterine tubes because they connect the ovaries to the uterus, allowing eggs to travel from the ovaries to the uterus. The other choices are incorrect because: A: Vas deferens is a tube that carries sperm from the epididymis to the urethra in males. B: Epididymis is a coiled tube located on the back of each testicle where sperm mature. D: Vagina is the muscular tube that connects the cervix to the external genitalia in females.
