Question

What occurs during the implantation stage of human reproduction?

Options

• The blastocyst attaches to the uterine wall

• Gametes are formed in the gonads

• The baby is delivered from the uterus

• The embryo develops into a foetus

Answer 1

Implantation is the stage where the developing blastocyst attaches to the uterine wall. This attachment is essential for the embryo to receive nutrients and oxygen from the mother's blood supply, allowing it to continue developing. Implantation occurs after fertilisation and before the gestation period.
