Female and Male Reproductive System Flashcards
what is the ovary?
where egg cells are formed by meiosis (in the follicle) - produces hormones oestrogen and progesterone
what is the oviduct?
egg cells travel down this to the uterus - lined with cilia which move the cell and is the site of fertilisation
what is the uterus (womb)?
a lining forms in the uterus, where the embryo will implant. the foetus develops in the uterus, which has a thicker muscular wall - this contracts during labour
what is the cervix?
narrow opening to the uterus - this dilates during labour, to allow the baby to be born
what is the vagina?
muscular tube that leads from the cervix to the outside of the woman’s body. a man’s penis goes into the woman’s vagina during sexual intercourse and the baby passes through the vagina when it is born
what are the testes?
where sperm cells are formed by meiosis - produces the hormone testosterone
what is the sperm duct?
maturing sperm are transported along this tube
what are the seminal vesicles and the prostate gland?
they release liquids into the sperm duct, which mixes with the sperm cells to form semen - the liquid provides nutrients to the sperm
what is the penis?
transports urine and semen out of the body. contains tissue which fills with blood to become erect; this helps to pass the semen out of the body and into the female’s vagina during sexual intercourse
what is the urethra?
tube inside the penis which can transport either urine or semen
