Luteal phase D. Ovulation \_\_\_\_\_\_10. The male reproductive system includes all of the following **EXCEPT**\... A. testes B. follicles C. vas deferens D. prostate gland **Part II -- Modified True or False** Directions: Write TRUE if the statement is correct. If it is FALSE, change the [underlined] word to make the statement correct. \_\_\_\_\_\_\_\_\_\_\_\_\_11. The corpus luteum produces [estrogen], which helps maintain the uterine lining during the luteal phase of the ovarian cycle. \_\_\_\_\_\_\_\_\_\_\_\_\_12. The sperm cell consists of three main parts: the head, the [cytoplasm], and the tail. \_\_\_\_\_\_\_\_\_\_\_\_\_13. [Luteinizing] hormone triggers ovulation in females and stimulates the production of testosterone in males. \_\_\_\_\_\_\_\_\_\_\_\_\_14. [Menstrual] phase begins on the 15th day and lasts until the end of the cycle. \_\_\_\_\_\_\_\_\_\_\_\_\_15. Follicular phase also begins on the first day of menstruation, but it lasts until the [10th] day of the ovarian cycle. \_\_\_\_\_\_\_\_\_\_\_\_\_16. The process of an egg and sperm joining together is called [reproduction]. \_\_\_\_\_\_\_\_\_\_\_\_\_17. The scrotum is located [outside] the body to keep the sperm alive. \_\_\_\_\_\_\_\_\_\_\_\_\_18. Both urine and sperm exit through the [urethra] in the penis. \_\_\_\_\_\_\_\_\_\_\_\_\_19. The upper reproductive parts of females are uterus, oviducts, and [vulva]. \_\_\_\_\_\_\_\_\_\_\_\_\_20. If the egg is not fertilized, it starts to break down in the uterus then leaves through [vagina]. **Part III -- Sequence** Directions: Analyze the statements below and arrange the stages of the ovarian cycle in chronological order. Use letters, with **A** as the first day of follicular stage and **J** as the menstrual phase. \_\_\_\_\_\_\_\_21. The primary follicles mature into secondary follicles, with increasing levels of estrogen. \_\_\_\_\_\_\_\_22. The ruptured follicle transforms into the corpus luteum, which secretes progesterone. \_\_\_\_\_\_\_\_23. The uterine lining sheds, and menstruation begins. \_\_\_\_\_\_\_\_24. The mature follicle ruptures, and the egg is released during ovulation. \_\_\_\_\_\_\_\_25. If fertilization does not occur, the corpus luteum degenerates, leading to a drop in progesterone. \_\_\_\_\_\_\_\_26. The dominant follicle emerges and estrogen levels continue to rise. \_\_\_\_\_\_\_\_27. The follicular phase begins, with the maturation of existing follicles into primary follicles. \_\_\_\_\_\_\_\_28. The menstrual phase occurs, marking the start of a new cycle. \_\_\_\_\_\_\_\_29. Progesterone levels rise as the corpus luteum supports the uterine lining for potential implantation. \_\_\_\_\_\_\_\_30. A surge in luteinizing hormone (LH) triggers ovulation.
