Phases of the Menstrual Cycle

Menstrual Cycle

It is the body's way of ensuring that the reproductive system works efficiently

Menstruation Phase

This is the phase where the lining of the uterus sheds, leading to bleeding through the vagina

Menstruation Phase

This happens if the egg is not fertilized

3-7 days

Typically, how long does the menstruation phase last?

Menstruation Phase

Phase where hormones drop, signaling the body to shed the uterine lining

Menstrual Flow

It is made up of blood, uterine lining, and other fluids

Menstruation

It is the way of resetting for a new cycle

Menstruation

It shows that the reproductive system is working and preparing for potential energy

Follicular Phase

This phase starts on the first day if menstruation and continues until ovulation

Follicular Phase

Phase where a hormone is released to stimulate the ovaries to produce follicles

Pituitary Gland

This gland in the brain releases the hormone in the follicular phase

Follicle-Stimulating Hormone

This is the hormone released in the follicular phase

Follicles

These are small sacs that contain immature eggs

Follicular Phase

Phase where one follicle becomes dominant and the egg inside it matures

Follicular Phase

Phase where estrogen levels increase, causing the uterine lining to thicken in preparation for a fertilized egg

Follicular Phase

This phase is like preparing a fertile ground where an egg can implant if fertilized

Ovulation Phase

This phase occurs midway through cycle

14th day

In the 28-day menstrual cycle, which day does the ovulation cycle begin?

Ovulation Phase

Phase where a surge of luteinizing hormone triggers the release of a mature egg from the ovary

Ovulation Phase

This is the phase where the egg travels through the fallopian tube, where it can be fertilized by sperm

Ovulation Phase

Most fertile phase of the cycle

Ovulation

It is the key phase for reproduction

Corpus Luteum

After ovulation, the follicle transforms into the --, which releases a hormone

Progesterone

What hormone does the corpus luteum produce?

Luteal Phase

Phase where the follicle transforms into the corpus luteum

Progesterone

This hormone maintains the thickened uterine lining to prepare for a fertilized egg

Luteal Phase

Phase where progesterone maintains the uterine lining to prepare for a fertilized egg

Uterine Lining

If the egg is fertilized, the egg is implanted in the — and the body begins pregnancy

Corpus Luteum

If the egg is not fertilized, the -- breaks down, progesterone levels drop, and the uterine lining sheds, starting a new cycle

Luteal Phase

Phase that ensures the body is ready for pregnancy or menstrual cycle

Luteal Phase

Phase where the fertilized egg is implanted on the uterine lining and begins pregnancy

Luteal Phase

Phase where the egg is unfertilized that causes the corpus luteum to break down, progesterone levels drop, and uterine lining sheds to start a new cycle

Menstruation

Its key hormones are low estrogen and progesterone

Menstruation

Its main event is the shedding of the uterine lining

Follicular Phase

Its key hormones are FSH and rising estrogen

Follicular Phas

Its main events are the maturing of an egg and the thickenig of the uterine lining

Follicular phase

It lasts day 1 to ovulation

Ovulation

Its key hormones are LH and high estrogen

Ovulation

Its main event is the release of the mature egg

Luteal Phase

Its key hormones are progesterone and some estrogen

Luteal Phase

Its main events are the formation of the corpus luteum and the preparation for pregnancy
