passes out during birth.

SummaryMale reproductive

system

Testis–produce sperms

Penis – deposits sperms into vagina

Sperm duct – for the sperms to travel to the penis

Female reproductive system

Ovary – produce eggs

Oviduct – carries the egg to the uterus

Uterus – place for embryo development

Vagina – place where sperms are deposited and passage for foetus during birth
