Solution
Post-pubertal females:
Post-pubertal females are those who have attained the age of puberty/sexual maturity and show cyclic changes in their uterine wall every month, a phenomenon called the menstrual cycle.
Such females contain fluid-filled cavities that contain the dominant egg/ovum inside their ovaries. These cavities are called follicles.
One such mature fluid-filled cavity is called the Graafian follicle.
On maturation, the Graafian follicle bursts and releases a fully mature dominant egg inside the fallopian tube/oviduct towards the uterus.
Inside the uterus, the egg remains for about 48 hours.
During this time, in the absence of fertilization with a sperm, the egg eventually dies. Following this, a new cycle of egg maturation starts and follows the same cyclic events.
