What's the difference b/w vulva and vagina and urethra?

vulva is the external genital organs of the female. vagina recieves the male sexual organ during sexual intercource and it is where the sperms are deposited, while the urethra carries urine from the bladder, in men it delivers both urine and simenal fluid but at different times. (vulva isnt menthioned in details in any of the books i have)
