3.8 understand how the structure of the male and female reproductive systems are adapted for their functions

Male Reproductive System:


Glands: Produces semen that will provide sperm cells with nutrients.
Sperm Ducts: Sperm passes through sperm duct to be mixed with fluids produced by glands.
Urethra: Tube inside the penis that carries urine or semen. Ring of muscle prevents the two mixing.
Testes: Contained in the scrotum, produces sperm and testosterone.
Penis: Passes urine and semen out.


Female Reproductive System:

Fallopian tube: connects ovary to the uterus, lined with ciliated cells to push released egg into the uterus for fertilisation.
Ovary: produces female gametes (ova) which will mature and develop when FSH is released.
Uterus: muscular bag with a soft lining (endometrium) where a fertilised egg will be implanted to develop into a fetus.
Cervix: a ring of muscle to keep developing fetus in place during pregnancy.
Urethra: tube that passes urine out of the body.
Vagina: muscular tube that leads to the uterus
