Answer 1

Answer:

1.Fertilization takes place in the fallopian tubes, which connect the ovaries to the uterus. Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube.

2.The male accessory ducts (vasa efferentia, epididymis, vas deferens, and rete testis) serve to store spermatozoa and to transport them outside urethra during ejaculation. Male accessory glands are seminal vesicles, prostate glands, and bulbourethral glands which contribute seminal plasma to semen.
