RECAP THE CONCEPTS

Male reproductive system

• The male reproductive system consists of the penis and testes (testicles).

• Tiny sperm cells are produced inside the testes.

• Sperm cells travel out of the testes through the sperm ducts.

Female reproductive system

• The female reproductive system consists of the ovaries, fallopian tubes, womb and vagina.

• Ovaries release one egg cell every 28 days (approximately).

• The eggs travel down the fallopian tubes to the womb. 

Heredity

• Heredity is the passing on of characteristics from parents to young.
  

• The nucleus in our cells contain hereditary information that determines our characteristics (traits), e.g. colour of our eyes or skin.
