3 How the Female Reproductive System Works

4 Female Puberty Girls usually begin the process of puberty between the ages of 9 and 13, slightly earlier than boys Girls usually begin the process of puberty between the ages of 9 and 13, slightly earlier than boys At this time the body releases the female sex hormone estrogen that causes physical changes to occur. At this time the body releases the female sex hormone estrogen that causes physical changes to occur.

While girls are often fully developed by age 16, some continue to mature physically through age 18.

5 Female Puberty Changes that occur: Changes that occur: Growth spurt Growth spurt Acne may appear Acne may appear Underarm hair appears Underarm hair appears Perspiration increases Perspiration increases Breasts develop Breasts develop Waistline narrows Waistline narrows Hips widen Uterus and ovaries enlarge Pubic hair appears External genitals enlarge Ovulation occurs Menstruation begins Long bone growth stops

6 Ovary Female reproductive organs that produce eggs and the female sex hormone estrogen and progesterone Female reproductive organs that produce eggs and the female sex hormone estrogen and progesterone Each ovary is about the size of the top joint of a thumb and contains 1-2 million eggs Each ovary is about the size of the top joint of a thumb and contains 1-2 million eggs

7 Estrogen Female sex hormone that causes sex hormones to mature into adult shape and size Female sex hormone that causes sex hormones to mature into adult shape and size Causes secondary sex characteristics to develop, bones to strengthen, regulate the menstrual cycle, and prepare the body for pregnancy Causes secondary sex characteristics to develop, bones to strengthen, regulate the menstrual cycle, and prepare the body for pregnancy

8 Eggs Sex cells that are produced in the ovaries Sex cells that are produced in the ovaries Eggs start to develop before the female is born Eggs start to develop before the female is born By the time the female is born, only 700,000 eggs remain from the 1-2 million that were present in the female while in the womb By the time the female is born, only 700,000 eggs remain from the 1-2 million that were present in the female while in the womb 400,000 eggs will remain by the time a girl reaches puberty 400,000 eggs will remain by the time a girl reaches puberty About 400 eggs will mature in a womens life About 400 eggs will mature in a womens life Each egg is about.135mm or the size of a very sharp pencil Each egg is about.135mm or the size of a very sharp pencil

9 Vagina Reproductive organ that connects the outside of the womens body to the uterus Reproductive organ that connects the outside of the womens body to the uterus Secretes acid type liquid at certain times of the month that can kill sperm Secretes acid type liquid at certain times of the month that can kill sperm Elastic like skin that can stretch as needed Elastic like skin that can stretch as needed Allows menstrual fluid to exit the body and is part of the birth canal Allows menstrual fluid to exit the body and is part of the birth canal

10 Urethra The long narrow tube that carries urine from the bladder out of the body The long narrow tube that carries urine from the bladder out of the body

11 Fallopian Tubes Transports the egg from the ovary to the uterus Transports the egg from the ovary to the uterus The end of the fallopian tube contains fimbria that help to pull the ripened egg out of the ovary and down the tube The end of the fallopian tube contains fimbria that help to pull the ripened egg out of the ovary and down the tube This organ is about 4-5 inches long and is lined with cilia that help to sweep the egg down the tube This organ is about 4-5 inches long and is lined with cilia that help to sweep the egg down the tube

12 Uterus A pear shaped, muscular cavity about the size of a fist A pear shaped, muscular cavity about the size of a fist It is found at the top of the vagina It is found at the top of the vagina The uterus is the organ where a fertilized egg is implanted so a baby may develop The uterus is the organ where a fertilized egg is implanted so a baby may develop The uterus is known as the womb The uterus is known as the womb

13 Cervix Where the uterus meets the vagina Where the uterus meets the vagina At times it gives off substances that kill the sperm and at other times helps the sperm to live easier At times it gives off substances that kill the sperm and at other times helps the sperm to live easier

14 Ovulation The releasing of the egg from the ovary The releasing of the egg from the ovary Each month in the left or right ovary, an egg ripens and is swept into the fallopian tube where it is capable of being fertilized Each month in the left or right ovary, an egg ripens and is swept into the fallopian tube where it is capable of being fertilized It takes about 72 hours for the egg to travel the tube, most sperm have the same lifespan It takes about 72 hours for the egg to travel the tube, most sperm have the same lifespan The egg will only live a few hours in the uterus if not fertilized The egg will only live a few hours in the uterus if not fertilized

15 Bladder A triangular sac that stores urine before it is excreted out of the body A triangular sac that stores urine before it is excreted out of the body

16 Menstrual Cycle A monthly series of hormone controlled changes that prepare the body for pregnancy A monthly series of hormone controlled changes that prepare the body for pregnancy If the egg is not fertilized, menstruation occurs If the egg is not fertilized, menstruation occurs The lining of the uterus is shed, about 2-4oz. over 3-7 days The lining of the uterus is shed, about 2-4oz. over 3-7 days If fertilization occurs, bleeding stops and a mucus plug is formed If fertilization occurs, bleeding stops and a mucus plug is formed
