Explanation:

The egg or ovum is released at the ovary. It is then captured by the fimbriae which are made up of ciliated and finger-like projections. From the fimbriae it moves through the infundibulum, which is a funnel-shaped opening. It progresses through the ampulla which is the widest section of the fallopian tube and where fertilization usually occurs. From there on through the body of the oviduct and through the isthmus which is a narrow opening connecting the fallopian tube to the uterine cavity.

From the uterine cavity it passes through the internal os (which connects the uterine cavity to the cervical canal), the cervical canal and through the external os to the vagina. From the vagina to the vaginal orifice or vestibule and out of the body.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
