Question

The thick and spongy uterine wall breaks when:


  1. The egg is not released by ovary

  2. The egg is not fertilized by sperm

  3. Fertilization of egg and sperm occurs

  4. Embryo starts developing in uterus


Solution

The correct option is B

The egg is not fertilized by sperm


In females, the uterus prepares itself to receive a mature egg released from ovary every month.  In case the fertilization of egg and sperm does not occur, the thick and spongy lining of uterus is no more required. It then breaks and is released from vagina as blood and mucous.
