How the Female Reproductive System Works

Ovaries Are the female reproductive organs that produce eggs Reproductive System 5th Grade Ovaries Are the female reproductive organs that produce eggs Eggs (ova) – sex cells that are produced by the ovaries and can be fertilized by sperm All of the eggs a female will ever have, are in her 2 ovaries when she is born Make the hormones estrogen and progesterone Regulate the monthly release of an egg and prepare the body for pregnancy

Vagina and Urethra Vagina Urethra 5th Grade Reproductive System 5th Grade Vagina and Urethra Vagina Female reproductive organ that connects the outside of the body to the uterus Receives sperm during reproduction Urethra Located above and separate from the vagina – carries urine from the bladder to the outside of the body

Fallopian Tubes and Uterus Reproductive System 5th Grade Fallopian Tubes and Uterus Fallopian tubes the female reproductive organs that transport an egg from the ovary to the uterus Uterus female reproductive organ that provides a place to support a developing human muscular cavity the size of a fist

5th Grade

How the Menstrual Cycle Works

Reproductive System 5th Grade Menstrual cycle A monthly series of hormone-controlled changes that prepare the uterine lining for a pregnancy Ovulation – the release of an egg from a follicle in the ovary High levels of estrogen and progesterone thicken and maintain the uterine lining If pregnancy does not occur – estrogen and progesterone levels quickly fall Menstruation – breakdown and discharge of the uterine lining out of the vagina Usually lasts between 3 and 7 days

Menstrual Cycle can vary Reproductive System 5th Grade Menstrual Cycle can vary Average cycle is 28 days Can vary from one individual to another and from month to month Ovulation usually occurs on the 14th day Environmental factors can influence the timing of a cycle Stress Exercise Weight gain or loss Diet Travel Illness
