Question

What changes are observed in the uterus if fertilization does not occur?

Answer 1

Fertilization:

1. Fertilization is the process of a haploid egg cell and sperm cell fusing to generate a diploid zygote that develops into an embryo.
2. The process of fertilization takes place in the fallopian tube that connects the ovary to the uterus.

Changes observed in the uterus if fertilization does not occur:

1. The lining of the uterus (endometrium) becomes thick, vascular, and spongy once a month in preparation for providing space and nutrition for a fertilized embryo.
2. The endometrial lining of the uterus will break down if the egg is not fertilized.
3. Menstruation is the process by which the unfertilized egg and ruptured endometrium are ejected from the body in the form of blood and mucus through the vagina.
