The Reproductive System
By Jen and Allison
Purpose and Function
- To create new life

- Functions:

Female Reproductive Parts and Functions
Produce, store, and release egg cell
Make sex hormones
Male Reproductive System and Functions
Path of Sperm and Egg Cells
Sperm Cell Path
Egg Cell Path
Vas Deferens
Seminal Vesicle
Prostate Gland
Fallopian Tube
Different Processes of Human Reproduction
- Sexual Reproduction
- Intrauterine Insemination (IUI)
- In Vitro Fertilization
- Donor Eggs
Working With Other Body Systems
- Circulatory System
- Endocrine System
- Blood carries nutrients to developing embryo in uterus
- Sex hormones released into blood
1. Make sperm cells and egg cells
2. Move and protect egg and sperm
3. Nurture developing embryo
4. Produce hormones
Healthy Life Choices
No dirt or bacteria infecting organs
Keep away bacteria
See if anything is wrong
Keep system healthy and functioning
Avoid diseases
Unhealthy Life Choices
Hormones cannot be produced
Hormone levels are changed
Abnormal growth
Related Illnesses
- Sexually transmitted diseases
- Infertility
- Delayed sexual development
Can't produce healthy egg or sperm cells.
Caused by genetics, chemicals or medication, and health.
Prevented by diet and exercise.
Bacteria or virus given to you by someone else.
Caused by sexual intercourse.
Prevented by not having sexual intercourse.
Reproductive system doesn't grow or change.
Caused by genetics, poor diet, chemicals.
Prevented by staying healthy.
Fun Facts
- If you lost your reproductive organs, you can still live.
- The largest cell in the female is the egg cell.
- About 500 million sperm cells mature every day in a male.
- The life span of an egg is 12-24 hours. The life span of a sperm cell is 2-3 days.
Through sexual intercourse
Through donated sperm
Through lab procedure
Through surrogate female
- Ovary
- Fallopian Tube
- Uterus
- Cervix
Connect uterus to ovary
Carries egg cell
Nurture developing fetus
Connects uterus to vagina
Protects uterus
Where the penis is inserted during sexual intercourse
Pathway for birth
Pathway for egg released
- Good hygiene
- Change underwear daily
- Visit doctor regularly
- Abstinence (no sexual intercourse)
- Balanced diet & Good sleep
- Smoking
- Poor diet
- produce and store sperm cells
-produce testosterone
- stores sperm
- moves semen
- carries semen and urine out
- protects urethra
-inserted into the vagina during sexual intercourse
- makes fluid to mix with sperm
Vas Deferens
Seminal vesicle and Prostate Gland
Male Reproductive System
- A male who has reached puberty produces millions of sperm cells everyday

- Males are born with all the cells that become sperm cells, but they don't actually become sperm cells until puberty, when the testosterone that is being released changes them from small cells to sperm cells.

Sperm cell looks like a tad pole
head - has all the genes
tail - helps it to move through the system
- The major function of the sperm is to fertilize a female egg cell during sexual intercourse. This is how reproduction occurs.
Female Reproductive System
Sperm Cells
Egg Cells
-When a female is born, she is born with thousands of inactive egg cells in her ovaries
- At the end of puberty, once a month the ovaries release one egg at a time. Then it travels through the fallopian tubes and to the uterus.
- The major function of the egg cell is to get fertilized by a sperm cell. If it does not, it exits out the female body.
- If it does get fertilized by a sperm, it becomes a zygote, which eventually divides until it becomes a baby embryo
