1. The Reproductive System

2. LET’S GET COMFORTABLE WITH THE VOCAB!!
SPERM!
PENIS!
OVARY!
UTERUS!
Egg!
TESTES!
VAGINA!

3. What is REPRODUCTION…? How DNA gets passed from parent to offspring
All living things do it- somehow.
What are the 2 types of reproduction?

4. 2 Types of Reproduction:
Sexual- requires 2 organisms; has more genetic variation, but takes longer
Asexual- requires no partner; is much quicker, but very little genetic variation

5. Main Functions Develops male/female physical characteristics
Produce sex cells
Assist in fertilization
Produce offspring

6. Male Reproductive System
Has both internal and external organs

7. Male Reproductive System
Penis – external male organ through which urine and semen flow out the body
Scrotum – protective sac surrounding testes
Testes – male sex gland, produces testosterone sperm
Sperm – male reproductive cell, made in testes
Urethra – duct where semen and urine travel through
urethra
testes

9. Female Reproductive System
Has only internal reproductive organs

10. Female Organs
Ovaries – female sex glands, produces estrogen, produce egg cells
Egg – female reproductive cell
Oviduct – tube that connects ovary to uterus; where fertilization occurs (a.k.a. Fallopian tube)
Uterus – hollow organ with muscular walls, site where fertilized egg develops into an embryo
Vagina – tube connecting uterus to outside of body
releases

12. The Menstrual Cycle
Every month, the adult female body prepares for a potential pregnancy
If no pregnancy happens, the cycle repeats itself every 4 weeks
The menstrual cycle starts during puberty and ends at menopause

14. How is a new offspring created?
When a sperm fertilizes an egg, a zygote is created, which becomes an embryo
How many chromosomes are in the sperm? The egg? The zygote?
