Identify the incorrect statement regarding female reproductive system?
| 1. | The first meiotic division of a primary oocyte forms two secondary oocytes that remain in this stage unless fertilization occurs. |
| 2. | Uterine tube, fallopian tube, and oviduct are terms used to refer to the same organ. |

Select the correct sequence for the transport of sperm cells in the male reproductive system:
| 1. | Testis → Epididymis → Vasa efferentia → Vas deferens → Ejaculatory duct → Inguinal canal → Urethra → Urethral meatus |
| 2. | Testis → Epididymis → Vasa efferentia → Rete testis → Inguinal canal → Urethra |
| 3. | Seminiferous tubules → Rete testis → Vasa efferentia → Epididymus → Vas deferens → Ejaculatory duct → Urethra → Urethral meatus |
| 4. | Seminiferous tubules → Vasa efferentia → Epididymis → Inguinal canal → Urethra |
