|
Function of the cervix |
Ring of muscle
Separating the vagina from the uterus |
|
|
Function of the funnel of the oviduct |
Directs and ovum (egg) from the ovary into the oviduct |
|
|
Function of the oviduct |
Carries an ovum to the uterus with propulsion provided by tiny cilia in the wall
Site of fertilisation |
|
|
Function of the ovary |
Contains follicles in which ova (eggs) are produced |
|
|
Function of the urethra (female) |
Carries urine from the bladder |
|
|
Function of the uterus |
Where the fetus develops |
|
|
Function of the vagina |
Receives the male penis during sexual intercourse
Sperm are deposited here |
|
|
Function of the epididymis |
Mass of tubes in which sperm are stored |
|
|
Function of the penis |
Can become firm To insert into the vagina during sexual intercourse In order to transfer sperm |
|
|
Function of the prostate gland |
Adds fluid and nutrients to sperm to form semen |
|
|
Function of the scrotum |
A sac that holds the testes outside the body, Keeping them cooler than body body temperature |

|
Fertilisation is the.... |
Fusion of the nuclei from a male gamete (sperm) and a female gamete (ovum) |
|
|
Female Gametes- Egg cell |
Surrounded by jelly coat -protects the egg -prevents more than one sperm entering and fertilising egg Contains large amount of cytoplasm, rich in fats and proteins -fat acts as energy stores -proteins available for growth |
|
|
Male gametes- Sperm cell |
Tip of cell carries an acrosome -which secretes enzymes capable of digesting a path into the egg cell through the jelly coat so fertilisation can take place Flagellum (tail) moves and propels sperm forward Cytoplasm of mid-piece of sperm contains many mitochondria -they carry out respiration, providing energy for tail movement |
|
|
Comparing male and female gametes |
Sperm smaller than eggs Sperm produced in much larger numbers |
