Summary
Reproduction in humans involves sexual reproduction, where a male and female mate to pass on characteristics to their offspring.
- Sexual Reproduction — requires a male and female to mate, enabling the survival of humans. Example: Humans inherit traits like earlobe attachment and eyelid type from their parents.
- Fertilisation — the fusion of the male reproductive cell (sperm) and the female reproductive cell (egg). Example: Fertilisation leads to the formation of a fertilised egg that grows into a baby.
- Ovary — part of the female reproductive organ that produces eggs. Example: The ovary releases an egg during the reproductive cycle.
- Testis — part of the male reproductive organ that produces sperm. Example: The testis is responsible for producing sperm necessary for fertilisation.
- Umbilical Cord — connects the developing baby to the mother, providing nutrients. Example: The umbilical cord supplies the baby with nutrients from the mother's blood.
