|---|---|

| sperm formation | spermatogenesis |
| sperm leaves the testes through the | efferent ductules |
| it takes sperm 20 days to move through this structure, here they gain the ability to swim and fertilize an egg | duct of the epididymis |
| from the duct of the epididymis the sperm travel here (three more structures) | vas deferens, ejaculatory duct, urethra |
| accessory glands which lie on the posterior surface of the urinary bladder and secrete about 60% of the volume of semen | seminal vessels |
| encircles the prostratic urethra, contains substances that enhance sperm motility | prostate gland |
| pea-sized glands inferior to the prostate gland, produce a mucus which cleanses the urethra before ejaculation | bulbourethral glands |
| two components of male external genitalia | penis and scrotum |
| primary sex organ of the male | testes |
| primary sex organ of the female | ovaries |
| lateral region of the uterine tubes | infundibulum |
| intermediate region of the uterine tube | ampulla |
| medial region of the uterine tube | isthmus |
| usual site of the fertilization of the egg | uterine tubes (fallopian tubes) |
| female reproductive organ which prepares to support a developing embryo | uterus |
| outer layer of the uterine wall | perimetrium |
| middle muscle layer of the uterine wall | myometrium |
| inner layer of the uterine wall where the fertilized egg implants | endometrium |
| receives the penis during sexual intercourse | birth canal |
| the female external genitalia | vulva |
| modified sweat glands used to nourish infants | mammary glands |
