Know your body - women

Ovary - You have two ovaries, each about the size of an almond, which produce the eggs, or ova.

Womb, or uterus - This is about the size and shape of a small, upside-down pear. It is made of muscle and grows in size as the baby grows.

Fallopian tube - You have two tubes leading from the ovaries to the womb.

Bladder - This is a bag made of muscle and tissue which holds urine.

Urethra, or water passage - This is a tube which carries urine from the bladder.

Vagina - This is a tube about 8 cm (3 in) long. It leads from the cervix to the vulva, where it opens between the legs. The vagina is very elastic so it can easily stretch around a man’s penis, or when a baby is born.

Anus - This is an opening at the lower end of the bowel which is kept closed by two muscles.

Cervix - This is the neck of the womb. It is normally almost closed, with just a small opening for blood to pass through during the monthly period.

Clitoris - This is a small, sensitive organ which swells and goes hard during sex. When the clitoris is stimulated during sex it can lead to orgasm.
