olga_2 [115]

Answer AND Explanation:

MALES

Testes: they are oval shaped structures that produce the male gametes and sex hormone called testosterone.

Seminiferous tubules: tubules where spermatogenesis occurs.

Vas deferens: are tubules which lead to the epididymis.

Epididymis: is along, coiled tube for storage of sperms. it contraction and relaxation pushes sperms out and allows ejaculation through the urethra.

Scrotum: contains the testes outside the body.

FEMALES

Ovary: these are oval-shaped structures that produce female gametes and sex hormones.

Oviduct: these are hollow structures with an expanded funnel-shaped opening which accepts the released ovum and directs it to the fallopian tube. Fertilization takes place in the oviduct  forming zygote.

Uterus: has an inner layer called endometrium which becomes folded and  vascularised to allow implantation. The endometrium nourishes the embryo..

Cervix: is a muscular ring between the uterus and the vagina. It secretes a plug of mucus, which prevents entry of pathogens and air

The vagina is a muscular copulatory canal into which penis enters. Vagina also allows passage of foetus during parturition.
