3.8 describe the structure and explain the function of the male and female reproductive systems

Male reproductive system
Testis- produce sperm cells, they are stored in the epididymus
Vas deference- carries sperm to the penis
The prostate- adds fluid to the sperm, creating semen (as does the seminal vesicles)
The urethra- carries sperm to the end of, and out of the penis.

Female reproductive system
Ovaries- produce eggs
Oviducts- carry the eggs to the uterus, is the site of fertilisation
Uterus- develops the fertilised egg on the placenta
Cervix- entrance to uterus

    the ovaries do not produce eggs- the eggs are stored there since birth- each woman has a certain number of eggs. if you say the ovaries produce eggs you will not get the mark.
