Human Reproduction

Humans reproduce sexually. Sexual reproduction involves the fusing of different cells to form a new life.

From sex cells to life

From sex cells to life

  • Gametes - these are the cells that are given from each partner.
  • The male will supply a sperm cell and the female will supply an egg cell.
Fertilisation of gametes

Fertilisation of gametes

  • Fertilisation - this is what happens when the sperm and egg (the gametes) fuse, or join together.
  • Fertilisation normally happens in the fallopian tubes.
Gestation and birth

Gestation and birth

  • Birth - this is the process whereby the baby is delivered, or born.

  • The female carries the offspring through gestation until they are born.
