Paper 1, Paper 2
The release of a mature egg from an ovary.
Revise: The Menstrual Cycle and Hormonal RegulationAround day 14 in a typical 28-day cycle, a mature egg is released from an ovary. This is ovulation. The egg enters the oviduct, also called the fallopian tube, and travels towards the uterus.
Distinguish egg maturation from egg release: FSH causes maturation; LH triggers ovulation.
A 28-day cycle with ovulation around day 14 is a typical model, not a fixed timetable for everyone.
Distinguish ovulation, the release of an egg from an ovary, from menstruation, the shedding of the uterus lining.
