What happens to an egg cell during ovulation?

All women are born with millions of immature egg cells in their ovaries. Ovulation happens when an ovary releases a mature egg through the fallopian tube. This process of getting an egg to mature will take approximately a month. Normally, only one of the pairs of ovaries will release a matured egg ready to be fertilized. Usually, it will take 12-24 hours before the matured ovum dies when not fertilized. But when they are fertilized, they cling to the walls of the uterus.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
