The Reproductive System Quizlet Questions
Question 1 of 5
Which hormone is produced by the corpus luteum that helps maintain pregnancy?
Correct Answer: C
Rationale: The correct answer is C: Progesterone. The corpus luteum produces progesterone, which is essential for maintaining the uterine lining and supporting early pregnancy. Progesterone helps prevent contractions of the uterus and supports the development of the placenta. Estrogen (A) is important for the initial thickening of the uterine lining but does not play a direct role in maintaining pregnancy. Testosterone (B) is not involved in pregnancy maintenance. Relaxin (D) helps relax the uterine muscles but is not primarily responsible for maintaining pregnancy.
Question 2 of 5
Which hormone is necessary for the growth of endometrial glands, which are important for the sustenance of a growing embryo until its implantation?
Correct Answer: C
Rationale: The correct answer is C: Progesterone. Progesterone is necessary for the growth of endometrial glands as it prepares the endometrium for implantation of the embryo. LH is responsible for ovulation, not endometrial gland growth. Testosterone is a male sex hormone and not directly involved in endometrial gland growth. Inhibin regulates FSH secretion, not endometrial gland growth.
Question 3 of 5
A mature ovarian follicle that is ready upper portion of the urethra just below to be ejected from an ovary is called a the junction with the urinary bladder. ________.
Correct Answer: D
Rationale: The correct answer is D: vesicular (Graafian) follicle. This structure is the final stage of maturation of an ovarian follicle before ovulation. It is characterized by a fluid-filled cavity and a bulging appearance on the surface of the ovary. It releases the mature egg during ovulation. Rationale: 1. Ejaculatory (choice A) relates to the male reproductive system, not the female reproductive system. 2. Primary oocyte (choice B) refers to an immature egg cell, not a mature follicle. 3. Seminal (choice C) is related to semen production in males, not the female ovary. In summary, the vesicular (Graafian) follicle (choice D) is the correct answer as it accurately describes the final stage of maturation of an ovarian follicle before ovulation.
Question 4 of 5
The spongy tissue of the penis fills
Correct Answer: D
Rationale: The spongy tissue of the penis fills with blood during an erection to cause the penis to become rigid. This process is essential for maintaining an erection during sexual activity. Spermatogenesis refers to the production of sperm, not the filling of spongy tissue. Circumcision does not involve the filling of spongy tissue with blood. Ejaculation is the release of semen and does not involve the filling of spongy tissue. Therefore, the correct answer is D as it accurately describes the physiological process of penile erection.
Question 5 of 5
Parturition occurs the fetus is the ________. approximately how many days after a
Correct Answer: D
Rationale: The correct answer is D: chorionic villi. Parturition occurs when the fetus releases cortisol, which stimulates the production of prostaglandins leading to uterine contractions. Chorionic villi are the fetal tissue that produces cortisol, making it the key factor triggering labor. A: Amnion is the innermost membrane around the fetus, not directly involved in labor initiation. B: Placenta plays a role in nutrient exchange but not in triggering labor. C: 180 days is a set time frame and does not relate to the process of parturition.
