During sexual reproduction in humans, male gametes, known as (1) _______________ , are produced in the (2) _______________ . During ejaculation, these gametes are released and must swim through the cervix and uterus into the (3) _______________ .

The female gamete, or (4) _______________ , is released from the (5) _______________ during a process called (6) _______________ .

If a male gamete successfully meets the female gamete, they fuse in a process called (7) _______________ . This fusion of haploid nuclei results in a single diploid cell called a (8) _______________ .

This diploid cell begins to divide by (9) _______________ to form a multicellular embryo, which eventually embeds itself into the lining of the uterus in a process called (10) _______________ .
