Human Reproduction (female reproduction system)

Ovaries

Produce eggs and the hormones oestrogen and progesterone

Fallopian tube

Transports egg to the uterus. Site of fertilisation

Uterus

Holds the developing baby during pregnancy

Endometrium

Allows attachment of the embryo during pregnancy

Cervix

Closes during pregnancy

Vagina

Holds penis during intercourse and acts as the birth canal

Name all the reproductive hormones

Oestrogen

Progesterone

Luteinising hormone

Follicle stimulating hormone

Oestrogen

Oestrogen causes the endometrium to be repaired so that it will be ready to receive an embryo if fertilisation occurs.

Progesterone

Progesterone causes the further repair of the endometrium.

Luteinising hormone

Luteinising hormone causes ovulation to occur on day 14.

LH causes the empty Graafian follicle to seal up and become the corpus luteum.

Follicle stimulating hormone

Causes a number of Graafian follicles in the ovary to develop

Stimulates cells in the follicles to secrete oestrogen

Ovulation

The release of an egg from an ovary once a month

Fertile period

Is the time during a menstrual cycle when an egg may be fertilised
