Human Reproductive System

4.2  Human Reproductive System

 

Male Reproductive System
 

 

Part Function
Seminal vesicle Secretes nutritional fluid for the sperms
Urethra A channel to discharge sperms and urine from the body
Sperm duct Transports sperms from the testis to the urethra inside the body
Penis Transfers sperms into the vagina of the female during copulation
Scrotum Holds and protects the testes
Testis Produces male gametes (sperms) and male sex hormones
Prostate glands Secrete fluid which contains nutrients and protects sperm cell

 Female Reproductive System

Part Function
Fallopian tube Place where fertilisation between sperm and ovum occurs
Ovary Produces female gamete (ovum) and female sex hormones
Uterus (womb) Place where the embryo develops and grows
Cervix Produces mucus to enable sperms to swim into the uterus
Vagina Receives sperms and as a channel through which a baby is born

 Comparison between the Male and Female Gametes

 

Sperm Ovum
Able to move Not able to move
Produced by testis Produced by ovary

Smallest cell in the male's body Largest cell in the female's body
Carries genetic information
