Reproduction in human beings

1. Reproduction in human beings Objectives At the end of the lesson, students should be able to: • Draw and identify the parts of the male and female reproductive organs. • State the functions of the male and female reproductive organs.

2. Reproduction in humans • The male reproductive system • The female reproductive system

5. The male reproductive system • There consists of 3 parts – testis, penis and sperm duct. • Testis (Testes) - A man has two testes. - Produces the male sex cells (sperms). • Penis - Organ which deposits sperms into the vagina of the female.

6. Sperm duct - A long tube along which the sperm travel from the testes to the penis.

7. SPERM

10. The female reproductive system • There consists of 4 parts – ovary, oviduct, uterus and vagina. • Ovary - A woman has two ovaries. - Produces the eggs or ova (ovum). • Oviduct - A tube which carries ova released from the ovary to the uterus.

11. Uterus - A pear-shaped structure where the embryo grows and develop. • Vagina - Place where the sperms are deposited. - The passage through which the foetus passes out during birth.

14. Summary Male 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
