It is expected that students will:
C14 Analyse the functional inter-relationships of the structures of the male reproductive system
C14.1 identify and give functions for each of the following:– testes (seminiferous tubules and interstitial cells)– scrotum– epididymis– ductus (vas) deferens– prostate gland– Cowper’s glands– seminal vesicles– penis– urethra
C14.2 describe the path of sperm from the seminiferous tubules to the urethral openingC14.3 list the components seminal fluid (as contributed by the Cowper’s glands, prostate
gland, and seminal vesicles), and describe the functions of each componentC14.4 identify the tail (flagellum), midpiece, head, and acrosome of a mature sperm and
state their functionsC14.5 describe the functions of testosteroneC14.6 describe the homeostatic regulation of testosterone levels by the hypothalamus,
anterior pituitary, and testes

C15 Analyse the functional inter-relationships of the structures of the female reproductive system
C15.1 identify and give functions for each of the following:– ovaries (follicles and corpus luteum)– oviducts (fallopian tubes)– uterus– endometrium– cervix– vagina– clitoris
C15.2 describe the functions of estrogenC15.3 describe the sequence of events in the ovarian cycle, with reference to the
follicular phase, ovulation, and the luteal phaseC15.4 describe the sequence of events in the uterine cycle, with reference to
menstruation, the proliferative phase, and the secretory phaseC15.5 describe the control of the ovarian and uterine cycles by hormones including
gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen, and progesterone
C15.6 describe the hormonal changes that occur as a result of implantation, including– production of human chorionic gonadotropin (HCG) to maintain the
corpus luteum– increased production of progesterone by the corpus luteum
C15.7 describe a positive feedback mechanism involving oxytocin
