The deferent duct joins with the ........ and forms.........:

Correct Answer: C

Rationale: The correct answer is C: the ejaculatory duct. The deferent duct, also known as the vas deferens, joins with the seminal vesicle duct to form the ejaculatory duct. This is where sperm from the testes and fluid from the seminal vesicles combine before entering the urethra during ejaculation. The other choices are incorrect because the seminal vesicle duct does not directly join with the deferent duct, the urethra is not formed by the deferent duct, and the epididymal duct is not involved in the formation of the ejaculatory duct.

Correct Answer: D

Rationale: The correct answer is D because the ovary is indeed the female gonad responsible for producing eggs and releasing female sex hormones like estrogen and progesterone. This is its primary function, making it the most accurate choice. Choice A is incorrect as the ovary's main role is reproductive rather than mixed. Choice B is incorrect as the ovary secretes both female sex hormones and eggs, not just hormones. Choice C is incorrect as ovules are part of the female reproductive system but not the main function of the ovary.

Correct Answer: C

Rationale: The correct answer is C because the Fallopian tubes are indeed located between the ovary and the uterus. This is essential for the transportation of the released ovum from the ovary to the uterus for possible fertilization. Choice A is incorrect as the Fallopian tubes are not solely muscular-membranous ducts; they have ciliated epithelial cells aiding in the movement of the ovum. Choice B is too broad, as the Fallopian tubes are just one part of the female reproductive system. Choice D is incorrect because the Fallopian tubes do not capture the ovule; rather, they provide a pathway for its transport.

Correct Answer: A

Rationale: The correct answer is A: uterine artery. The uterine artery provides blood supply to the Fallopian tubes. It arises from the internal iliac artery and gives off branches that vascularize the tubes. The ovarian artery primarily supplies blood to the ovaries, not the Fallopian tubes. The external iliac artery supplies the lower extremities, not the reproductive organs. The abdominal aorta is a main artery that gives rise to multiple branches supplying various organs, but it does not directly supply the Fallopian tubes.

Correct Answer: D

Rationale: The correct answer is D: 280 days. The pregnancy period, also known as gestation, typically lasts around 280 days from the first day of the last menstrual period to the birth of the baby. This duration is calculated based on the average length of a full-term pregnancy, which is approximately 40 weeks. It is important to note that individual pregnancies may vary slightly in duration, but the standard reference is 280 days. Explanation of other choices: A: 120 days - This is too short for a full-term pregnancy. B: Nine weeks - This is only around 63 days, which is far less than the average gestation period. C: 280 weeks - This is equivalent to around 1960 days, which is much longer than a typical pregnancy duration.
