Final answer:
Ovulation is the process in which a mature egg is released from the ovary, part of the female menstrual cycle.
Step-by-step explanation:
The release of an egg from the ovary is called ovulation. This process typically occurs once a month as part of the menstrual cycle in sexually mature females, except when a female is pregnant. During ovulation, a mature egg is released from the ovary and is ready for fertilization. This is distinct from menstruation, which is the shedding of the uterine lining, and gestation, which refers to the period of fetal development in the womb. By understanding ovulation, one can better grasp the intricacies of the female reproductive cycle.
